I have been reloading for 20 years , but new to the 450 Bushmaster...........
What powder and bullets are people using?
Also I read about resizing 458 bullets down to 452.
Bullet resizing is new to me.....what equipment do I need?
Also should I buy a 452 die or does the bullet spring a little.....should I buy a 451 die?
Does the jacket lose its bond to the core when resizng jacketed bullets?
Thanks for any info:
