When I was a poor college student I handloaded for 7.7 Jap. My intention was to get an accurate and very low recoiling rifle due to financial limitations keeping me from a larger collection of guns. But the accuracy went down as the powder charge diminished, I went with a smaller grain bullet too, also I did not know about the dangers of reduced loads to the point of possible bursting guns at that time. When I used military surplus ammo with their large grain weighted bullets the accuracy was very good. It has been explained to me since that these military guns used a rifling twist favorable to heavier bullets.
I have a 30-06 that I have tried lead cast 199 grain bullets in using Reloader 7 powder. Reduced recoil, but severe rainbow trajectory at 100 yards, and mediocre groups, a waste of my time. I also have a Mauser 98 in 8 mm that really kicks with all military loads used, I have to use a slip on butt pad or I will get bruised up on my shoulder.
Would I be better off going with lighter cast bullets, even though they are really hard to find. Or just how small a jacketed bullet and powder load combination can I use for the above cartridges before the accuracy goes down the tube? For example...could I use a 110 gr or 130 gr bullet and still get decent accuracy out of my CZ 550 30-06 sporting rifle?
I do have several small bores that don't kick hard, like the .223 and .17 magnum rimfire, etc. But I would like to use my Mauser 98 more without having a recoil flinch develop, and my CZ 550 too.
Thanks
