Devistating on jackrabbitsġ0) Firearm tested in Remington 700, 24in barrel Notes: Shot a bit over one inch at 100 yards, 10 shot groups. Notes\Comments: This is the first run, second wasn't as tight (2834,43,17) Notes\Comments: Blasting ammo, progressive powder dropįirearm tested in: AR-15 Pencil bbl 1:9 Retro upper Powder charge weight: 26.0 slightly compressedįirearm tested in: AR-15 HBAR 1:9 Generic A2 20" Powder charge weight: 25.0 to 25.2 grains Once safety has been established you will likely find that this is an accurate load in your rifle.īullet weight and type: 69 grain MatchKing This load is warm, don't load 25.0 grains in your rifle without testing lighter charges first. Notes\Comments: Reloder 15 is just about optimum for bullets in the 69 grain weight range. Intended use: training, plinking, varmint killin', and Highpower competition Powder charge weight: 27.0 to 27.4 grainsįirearm tested in: AR based across the course rifle, Lilja 7 twist 3 groove barrel 24 inches long Cartridge headspace is set 0.0015 to 0.002 inches, or about 1.7XX from the case head to the 0.330 inch diameter datum on the shoulder.īullet weight and type: 52 grain MatchKing Cases are generally sized with a 0.245 inside diameter bushing through three loads, then 0.244 after that. In my experience 26.8 grains produces too little pressure to seal the case well, resulting in excess soot on the case shoulders. More gunpowder to 27.4 grains is safe, but spills before the bullet is seated as it fills the case to the top of the neck. Notes\Comments: Reloder 15 is slow for this combination of bullet weight and case capacity, hence the 27.0 grains fills a Winchester case to the bottom of the neck. Intended use: training, plinking, varmint killin', and reduced course Highpower competition
