Subsonic 7.62x39 stabilizing11/11/2023 ![]() ![]() Cases which are so modified must never be used with full powered loads! Always identify cases which are so modified by filing a deep groove across the rim and labeling them clearly to prevent their inadvertent use. Repeated loading of rimless cases with very mild loads results in the primer blast shoving the shoulder back, unless flash holes are enlarged with a No. These plinkers are more accurate than you can hold. Theses make accurate 50 yard small game loads which let you operate the action manually and save your precious cases. In the 7.62x39 case, use no more than 4 grains of the fast burning powders mentioned or 5 grains of the shotgun powders. I have also had fine results with 8 to 9 grains of medium rate burning pistol or shotgun powders, such as Unique, PB, Herco, or SR-4756 in any case of. These include, but are not limited to Bullseye, WW231, SR-7625, Green Dot, Red Dot or 700-X. 303 British, 7.62 NATO, 7.62x54R Russian and 30-06, I use 6-7 grains of almost any fast burning powder. For gas-check bullets loaded without the gas- checks, for cases like the. Gas checks are pressed onto bullet bases by hand prior to running into the lubricator-sizer. Bullets which are visually perfect are weighed and sorted into groups of +/- 0.5 grain for use in 200 yard matches. Bullets with minor visual defects are tumble-lubed in Lee Liquid Alox without sizing, and are used for plain base plinkers. I visually inspect each run of bullets and throw those with gross defects into the scrap box for remelting. ![]() This makes more sense to me than casting different bullets.īullet preparation is easy. Most of my rifle shooting is done with these two basic designs.īullets I intend for plain based loads are blunted using a flat-nosed top punch in my lubricator, providing a 1/8" flat which makes them more effective on small game and clearly distinguishes them from my heavier gas-checked loads. I started doing this in 1963 with the Lyman #311291. I substitute my usual gas-checked bullets, but without the gas-check. I use Mattern's plain-based "100 yard target load" to use up my minor visual defect culls for offhand and rapid-fire 100 yard practice. The "100 Yard Target and Small Game" Load I recommend it highly, particularly if you own a. 32 H&R Magnum which is ideal for this purpose. LBT makes a 130 grain flat-nosed gas-check bullet for the. 30 caliber cast small game bullet of the proper 125-130 grain weight. The 110-115 grain bullets intended for the. For bores smaller than 7mm, consult published data. 30 calibers, and 150-190 grains in the 8mm. They can be used as basic load data in most modern military rifles of 7mm or larger, with a standard weight cast bullet for the caliber, such as 140-170 grains in the 7x57, 150-180 grains in the. None of these loads are maximum when used in full-sized rifle cases such as the 30-40 Krag. 150 grain plain based "100-yard target/small game", 1050-1250 f.p.s., 7 grains of Bullseye or equivalent.ģ. 125 grain plain based "small game/gallery" 900-1000 f.p.s., 5 grains of Bullseye or equivalent.Ģ. I worked up equivalent charges to obtain the desired velocity ranges with modern powders, which provide a sound basis for loading cast bullets in any post-1898 military rifle from 7mm to 8mm:ġ. Four load classifications from Mattern (1932) cover all uses for the cast bullet military rifle. If a particular load will not work well without a filler, the powder is not suitable for those conditions of loading. This was once common practice, but it raises chamber pressure and under certain conditions contributes to chamber ringing. ![]() Nothing is more frustrating than a military rifle that shoots a foot high at 100 yards with surplus ammo when the sight is as low as it will go! Do not use inert fillers (Dacron or kapok) to take up excess empty space in the case. Cast bullets can make shooting that surplus rifle easy and economical.Īnd basic data works for many different guns.Ĭast bullet loads usually give a more useful zero at practical field ranges with military battle sights than do full power loads. ![]()
