Question bullet

[Nikkisdad]

I have come across several hundred of these bullets that i believe are Lyman # 457483. My question is are these GC designed or can they be loaded say with 2400/25gns, they average 390 grains. Would like to shoot them up for a plinking load - thanks guy's.

Thank you, I thought so. Can they be safely shot without the GC?

[runfiverun]

they can but 8-900 fps would be the window they would most likely work in.

How do you know what round the OP is talking about reloading...You must have psychic powers ! :?

45-70 guy's 1-18 twist rate using smokeless.

It really would not make any difference what cartridge he is shooting, because any cartridge of that caliber would do just fine at 8- 900 fps.

Been shooting that bullet in the 45-70 for 47+ years. Runfiverun is essentially correct. With 2400 powder you will find using a GC is best. W/o a GC try 8 - 10 gr Unique. Tilting the barrel up to position the powder uniformly will help.
