New Custom Made Barrels by Match Grade Machine

Custom barrels made by the best of the custom TC barrel manufacturers!

Buy in stock Contender and Encore barrels  for immediate shipment or have them custom build your barrel in 4-6 weeks!

Custom craftsmanship applied to streamlined CNC manufacturing processes.

No one else offers the wide range of options, steel picatinny rails, and barrel fluting that MGM does.

Order your barrel directly from Match Grade Machine, made however you want with their standard chamber or for $80 additional,  chambered by Mike Bellm to his specs for best accuracy with the full range of bullet weights and types.

Which chamber to choose?  It is a tough call since their  chamber work and mine are so, so close to the same.

MGM's .357 Maximum chamber has an excellent .358" diameter cylindrical throat, stepped down to .357"  far, far superior to factory forcing cone chambers, and very similar to my throating.   MGM's chamber is perfect for the vast majority of hunters and target shooters!

For the more meticulous shooters and those who like to experiment with the widest variety of bullet types.... .358" jacketed, .357" jacketed, and cast lead bullets, just ask them to hand the barrel to me to chamber for $80 more, billed separately by me.  I take the time to dial in bores, do all throating separately for the best co-axial alignment of the throat with the bore,  and cut a few tenths of a thousandth tighter throat.

MGM's chamber or mine?

Either will give hunting accuracy better than a big percentage of "varmint rifles!"

Custom .35 cal. Hunting Bullets

Hawk 180 gr. made to Mike Bellm's specs for optimum performance on game at both handgun and rifle velocities.  .357 Magnum revolver bullets have jackets too thin, jackets too brittle, and lead to hard to hold together on deer at velocities over about 1500 fps.

  • Hawk bullets are made with soft, pure copper jackets and soft lead that hold together, balling up into a perfect mushroom that penetrates instead of fragmenting before reaching vitals.
  • High ballistic coefficient for long range shots.
  • Ample soft lead exposed for expansion at long range while holding together at full speed on close shots.
  • Flat nose for use in .357 Magnum and .35 Remington tubular magazines.
  • Ideal for .357 Magnum, .357 Maximum,  .357 Herrett, .357 Bain & Davis, and similar rounds.
  • Crimp groove located 3/16" from the base for optimum case capacity.

$84 per hundred plus $7  shipping for up to 500 bullets.  Send check or money order to my new address:

.357 Remington Maximum beats many of the traditional factory loaded "deer cartridges" such as .30/30 Winchester and .35 Remington.

.357 Remington Maximum is one potent game harvesting machine with more energy potential than factory .30/30 Winchester and .35 Remington, roughly equal to factory .300 Savage, and not far behind .308 Winchester energy levels, but with much less powder, less muzzle blast, and less recoil!

Perfect for those states with straight wall case limits and/or overall cartridge case length limits where in most cases the .45 cal. rounds border on simply dumb when the .357 Maximum is so much more accurate and easier to shoot accurately with its moderate recoil.

.357 Maximum is a perfect starter gun for kids to learn and grow on.  It is easy to load moderately for closer range shots and lighter recoil.  Its moderate recoil makes it perfect for smallish folks such as the ladies and folks with disabilities who simply can not stand the recoil of the various .45's.

.357 Maximum when loaded down in a rifle length barrel is almost like shooting an air rifle.  But stoke it up and hear that little dog bark like a big dog!

Hornady XTP 158 gr. and especially their 180 gr. bullets have proven to be the best of the revolver type bullets for all applications..... handgun and rifle. Other brands and types of lead core bullets tend to blow up and not penetrate into vital organs when driven at rifle velocities close in.

Optimum overall rifle performance is 2300 to 2400 fps with 180 gr. bullets and 1800 (+) fps from 10" barrels at the short end of barrel lengths.
For full power loads like 30 gr. of AA-1680 give top velocities and energies for shots upwards of 250 yards or more.

Not quite as fast but a staple item is 296/110 with 23 gr. being a good functional maximum charge with 180 gr. bullets.

In between is Lil Gun with 27 gr.

IMPORTANT NOTE:  THROAT LENGTHS IN CUSTOM BARRELS VARY.  THROATS SHORTER THAN MINE WILL INCREASE PRESSURES.  AS ALWAYS, START ABOUT 10% LOW AND WORK UP!

Loads published in the major reloading manuals are pitifully understated, going to only go to about 40,000 psi.  SAAMI maximum is 48,000, and in the closed breech guns pressures can be run at the same levels as 5.56 NATO, about 54,000 psi.

My standard rule for maximum pressure that I have gone by for over 35 years is to take pressures to the point where a slight crater (ridge) begins to appear around the firing pin indent, then back off to just below that point.

Use only MAGNUM Rifle primers in .357 Maximum loads.
