- [ ] Crimp.
Hi Chaps,
I am hand loading for a 16 inch barrelled Rossi 92 in .44 Magnum. This is purely for target shooting. I have worked up pretty good load for 200 and 240 grain lead bullets. These are round nose flat points, .430 in diameter at velocities of 1000 to 1100 fps. These give me a 5 inch group at 50 yards. I am happy with this, so far, because the sights are Rossi out of the box and my eyesight, even with varifocal glasses, is still 58 years old.
Purely for the fun of it, I have loaded some magnum loads. 240 grain truncated cone FMJ, 215 and 255 grain gas checked lead semi wadcutter and 240 grain copper washed round nose. All are going at around 1500/1600 FPS The first two are ok, but the copper wash are all over the place. 10 inch groups. All rounds stabilise, no key holing. Previously I asked this forum for advice on 300 grain bullets that were key holing and the general advice to up the velocity from Special to Magnum levels worked well.
I put minimal crimp on the case mouth. Just enough to secure the bullet. Could this effect the copper wash accuracy.
