Why The .300 Ham'r Nails It For Hunting Mini 14 / 30 Cartridge & Chamber Line Up The .300 HAM’R (top) uses a stubbier bullet and a much longer case to generate a significant increase in case volume over the .300 BLK (bottom)

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:

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.

22 Nosler 224 Valkyrie

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.

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.

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.
