![]() 310" round ball, and one grain of Red Dot. I am NOT recommending this for anyone, as they are not "published" loads. ![]() If a 220 lead bullet can stabilize, you could possibly work up some effective loads by looking at the blk.įOR ENTERTAINMENT AND EDUCATIONAL PURPOSES ONLY I don't know how this would work, but the heavier your bullet is, the more effectively you can pursue low velocities. It's going to be hard to reach subsonic, but even so, without a suppressor, you must add up the normal muzzle blast and supersonic sound and just consider the overall noise level. Of bullseye scattered around that case erratically igniting as the charge builds isn't something I would want, and if a wide spread of velocities occur, it should be dumped. Yes, it is simply my opinion, but five grains. Essentially, if you use a bulkier charge of a moderately slow pistol powder, you will wind up with a load that functions a lot like a pistol round. A heavy bullet is the only way to do bit. 2400 isn't going to give you the low noise and velocity that you want, the charge will still be burning as it leaves the barrel. If you want my OPINION, using anything slower than unique isn't a great idea. I will be working down in 0.2 grain increments from loads listed above and want to stop well before the “stuck bullet” scenario I will be testing them over a chronographĪnd would like to know what would be the slowest velocity I could get without sticking a bullet in the barrel? I plan to use LaserCast 170 grain RNFPbb because they have a history with gmdr and I have collected some data on my own with these bullets.īut I'm open for suggestions to other bullets too. I would like to further reduce several of these loads a little more – so they are definitely sub-sonic Powder /Charge weight / Avg velocity / SD / ES / Group sizeīullseye / 5.6gr / 1128fps / 3fps / 8fps / 1.3 inchesĢ400 / 8.0gr / 1069 fps /15fps / 42fps/ 0.9 inches I have shot the following loads based on data from this website: I’m looking to make up some 30-30 Gallery loads to shoot out of my Marlin 30-30 w/ Microgroove 20” barrel at 25 yards
