Hello and welcome to our Ruger Mini conversion page. This page is long but filled with a lot of information about our accuracy conversions. Back when we started, we made it our goal to achieve the most accurate Mini conversions on the planet, bar none. We will be up front with you. We are not cheap! If you want a cheap conversion remember you get what you pay for. Do you want a Smith that does a few Mini’s a year with a prefabricated barrel, then installs the barrel and hopes it delivers the accuracy? Or do you want a company that makes the Mini their business and guarantees accuracy?! Cheap is not always better when it comes to accuracy. We know what the Mini’s weaknesses are through trial and error; you can't cut corners when it comes to accuracy! The Mini is well built and is worth every penny you spend with us to upgrade the rifle to match grade accuracy. We will review some comparisons between the popular AR 15 system and the Mini 14® system below.

The Mini 14® rifle system is a close copy of the Grand's receiver, bolt, and trigger group system. I don't have to tell you that it ends there, but they are still very similar. The Mini is a very tough, well-built system as it is. It will take all the abuse you can dish out and still be depended on to function when you need it. Here is a quote from General George Patton:"The M1 is the best battle weapon ever developed." The outcome of WW II proves this rifle to be battle worthy. That is also why even to this very day our troops in Iraq & Afghanistan prefer the dependability of the M14 which is the M1's predecessor over the AR 15! But you say to yourself, why put $600 plus into a rifle I only paid $500 for. Well below are some good reasons. Not to mention, have you priced a new M14 lately? Yes, it does shoot a 308 Winchester compared to a 223 Remington. But it also weighs more, cost more and doesn't come with an accuracy guarantee unless you pay extra. Don't feel stuck with the 223 caliber either, we do offer other calibers to suit your needs.

• Mini 14 - No hot gases are dumped into the bolt. So the bolt is not overcome by excessive heat! Also there is no carbon to build up and lock up the bolt!
• AR15 - Hot gases are dumped into the bolt to say the least and carbon will build up if not regularly cleaned causing a malfunction and or cease to operate condition.
• Mini 14 - All steel receiver and case hardened to a thickness of at least .020"
• AR15 - 75% aluminum alloy with the critical parts steel
• Mini 14 - Open bolt design is a close copy of the M14. The open bolt is very forgiving when it comes to dirt, dust or sand. The rifle clean or dirty just keeps ticking and ticking.
• AR 15- Closed bolt design. Just ask our troops about the plastic baggies they need to use to keep the sand from jamming up there rifles.
• Mini 14 - Self-cleaning gas system no buffer tube to collect moisture or dirt and lock up the buffer system.
• AR 15- Must be field stripped to clean trigger compartment, Buffer system, Bolt & carrier and gas tube system.
• Mini 14 - compact, versatile, and doesn't take up much space.
• AR15 - Large bulky
• Mini 14 - Field strips in seconds. Pop the trigger guard and the rifle practically dismantles itself.
• AR 15- Definitely slower to disassemble.
• Mini 14 - Now here the AR has an advantage over the Mini. Out of the box ACCURACY!
• AR 15 - Out of the box ACCURACY!
• Mini 14 - But here we can help! We can turn your Mini 14 into a rifle that will shoot right next to an AR15 after one of our conversions is completed. Now that we have discussed the pros and cons of the rifles you would have to say the Mini definitely has some advantages and we can take care of the disadvantages!

Built to bring .30-30 ballistics to the AR platform, the .300 Ham'r is on-target as a modern-day hunting cartridge.

What Makes the .300 Ham'r Such A Potent .30 Caliber:

• The parent case is .223 Remingtion necked up to accpet a .30-caliber bullet.
• Designed to Handle bulletweights from 110 to 150 rgains.
• Has an COL of 2.260 inches, so it functions in an AR-15 magazine.
• Capable of pushing a 150-grain bullet 2,240 fps at the muzzle.

In 2018, Bill Wilson of Wilson Combat announced the .300 Ham’r to match or better .30-30 Winchester performance in an AR magazine-length round. Thus, the cartridge was hatched to compete with the 6.5 Grendel, 6.8 SPC, 7.62×39 and .300 Blackout, with an eye toward killing wild pigs, thus the nod to “ham” in the name.Wilson himself says, “The project originally started way back in 2005, when J.D. Jones sent me one of his .300 Whisper uppers and a set of dies. Being an avid hunter, my primary interest was terminal performance, and the .300 Whisper just didn’t get the job done for me. So, at that point, I moved on to the 6.8 SPC and did a lot of work with it, and I killed a lot of hogs and deer.”

Then, in 2008, Remington came out with the .30 Rem. AR, and Wilson started getting the terminal performance on game that he was after. However, that caliber has its share of issues, such as a proprietary upper receiver, bolt carrier group and magazine. Also, shortly after Remington brought this cartridge to market, it quit supporting it. Wilson was also familiar with the 7.62×40, originally the brainchild of Kurt Buchert. Wilson Combat brought that round to market as the 7.62x40WT, a well-balanced cartridge that accepted virtually every .30-caliber bullet in the 110- to 135-grain weight range. However, to achieve this with the long-pointed bullets, the case length had to be limited to 1.565 inches, which wouldn’t allow the 7.62x40WT, in a rifle utilizing a 5.56/.223 bolt, to equal the legendary and time-proven .30-30 Winchester in terminal performance.

Wilson then selected bullets he wanted to use and reverse-engineered the case length to fit within the AR magwell, determining he could get .040-inch more case length than the 7.62×40 and .260-inch more than the .300 Blackout. Ron Reiber of Hodgdon Powder Company then recommended Hodgdon’s new CFEBLK powder, which improved accuracy and velocity with less pressure. A 1:15 twist rate for the barrels finished the equation.

General Comments

The .300 Ham’r has noticeable velocity and energy advantages over factory .300 Blackout rounds at the muzzle. With a 16.25-inch barrel, the .300 Ham’r sends a Sierra 110-grain hollowpoint to 2,600 fps with 1,651 ft-lbs. of energy, compared to the Hornady Black 110-grain V-Max at 2,395 fps MV and 1,401 ft-lbs. of energy. Likewise, the .300 Ham’r beats the 7.62×39 in a 16.25-inch barrel. The Ham’r shoots a Hornady 150-grain SST to a muzzle velocity of 2,240 fps with 1,671 ft-lbs. of energy. The factory 7.62×39 in the same barrel length and bullet weight (Winchester 150-grain Razorback XT) develops 2,056 fps and 1,408 ft-lbs. Out of a compact .30-30 lever-action with a 16-inch barrel, the shooter can expect to push a 150-grain bullet to about 2,250 fps.Wilson Combat supports the handloader with Lee and RCBS reloading dies, a Wilson Combat headspace/bullet seating gage, “WC 300 Ham’r” headstamped cases, and .308-caliber bullets. Wilson Combat has also introduced five AR-pattern rifles for the new chambering: Bill Wilson Ranch Rifle package, Tactical Hunter Model, Ultralight Ranger Model, Lightweight Hunter Model and the Ranger Model.

223 Remington Ackley Improved

223 Remington Ackley Improved is one of Ackley's most popular creations. Parent brass is readily available and reported velocity gains average 100-140 FPS depending on bullet weight.

Experience what shooters around the world are calling the ultimate varmint hunting platform when you transform your standard AR into a 22 Nosler. Approaching 22-250 velocities in a significantly smaller package the 22 Nosler yields 25% more case capacity than the 223 Rem/ 5.56 NATO, resulting in 14% more velocity and 30% more energy at the muzzle. The effortless two-step conversion allows shooters to achieve lightning fast, hard-hitting performance with popular varmint bullets, pushing a 55gr. Nosler Ballistic Tip at supercharged speeds of 3,350 fps and a 77gr. Custom Competition bullet at 2,950 fps.

Long Range Loads

Varmint Ammunition

Case Capacity

The 22 Nosler case holds 34.2gr H2O at overflow, and 31.2gr H2O with a 55gr Ballistic Tip® seated to 2.260" OAL. For comparison, a 223 Remington case holds 27.4gr H2O with a 55gr BT seated at 2.260" OAL. The 22 Nosler has almost 25% more case capacity than the 223 Remington.

Bolt Face

Bolt face dimensions are identical for the 22 Nosler and the 223 Remington / 5.56 NATO at .378".

Barrel Life

With standard use, you should see approximately 2,000 rounds when used in competition and as many as 4,000 rounds when used as a plinking rifle. However, this depends on how well the barrel is treated and cleaned.

∗ 24-inch Barrel ∗
The 6.8mm Remington SPC By Chuck Hawks The inadequacies of the 5.56mm NATO as a service rifle cartridge are well documented and have inspired many suggestions regarding possible replacements (some on this web site). Apparently someone in the U.S. Special Operations Command also realized the need for a more potent round and initiated work on a new cartridge designed to work in the M16 action. The new .270 caliber (6.8mm) cartridge is the result of at least a two year cooperative effort between Special Operations, the Army Marksmanship Unit, and Remington. Various calibers from .22 to .30 were tested before settling on a standard .277" diameter bullet, the same bullet diameter made famous in the .270 Winchester Remington is offering four 6.8mm SPC factory loads, all with 115 grain bullets. These include two target loads, a Core-Lokt Ultra hunting load, and a Metal Case military-type load. No varmint load is included. The four factory loads all have a muzzle velocity (MV) of 2800 fps and a muzzle energy (ME) of 2002 ft. lbs. from a 24" test barrel. At 100 yards the metal case bullet (BC .325) has a remaining velocity of 2523 fps and energy of 1625 ft. lbs. At 200 yards the velocity is 2262 fps and the energy 1307 ft. lbs. And at 300 yards the velocity is 2017 fps and the remaining energy 1039 ft. lbs. These figures are taken from Remington's 2004 catalog. The trajectory of the metal case bullet looks like this: +1.2" at 50 yards, +2.7" at 100 yards, + 2.8" at 150 yards, +1.4" at 200 yards, -3" at 267 yards, and -6.6" at 300 yards. The maximum point blank range (+/- 3") is thus 267 yards. These figures are computed for a rifle with a telescopic sight mounted 1.5" over the bore. This, just like the Army claimed, is similar to the trajectory of the .308 with a 150 grain bullet. The lighter weight .277" varmint and hunting bullets will presumably be the most popular choices in the 6.8mm SPC, and the latter are not thick on the ground. Suggested examples include the 90 grain Speer HP varmint bullet, 100 grain Barnes X-Bullet, 115 grain Sierra HPBT, 115 grain Remington Core-Lokt Ultra, and 120 grain Barnes X-Bullet. Fast to medium burning rifle powders such as RL-7, IMR 4198, IMR 3031, IMR 4895, H4198, H322, H335, and Benchmark are indicated in the 6.8mm SPC. The MAP of the 6.8mm SPC appears to be about 55,000 PSI. Here is some reloading data from the Hodgdon Powder Company: Starting Load - 90 grain Speer HP bullet, 26.0 grains of H4198 powder, MV 2810 fps, 47,700 PSI. Maximum Load - 90 grain Speer HP bullet, 28.6 grains of H4198 powder, MV 3012 fps, 54,000 PSI. Starting Load - 100 grain Barnes X-Bullet, 27.0 grains of H322 powder, MV 2502 fps, 37,700 PSI. Maximum Load - 100 grain Barnes X-Bullet, 30.0 grains of H322 powder, MV 2803 fps, 52,300 PSI. Starting Load - 115 grain Sierra HPBT bullet, 26.0 grains of H322 powder, MV 2421 fps, 43,500 PSI. Maximum Load - 115 grain Sierra HPBT bullet, 28.2 grains of H322 powder, MV 2608 fps, 53,300 PSI. These loads were chronographed in a 24" test barrel using Remington cases and Remington 9 1/2 primers. Note: A full length article about the 6.8mm SPC can be found on the Rifle Cartridge Page.
