Hi Everyone,
New to the forum, so I am certain that I am asking something that has been asked b/4, however need some assistance.
Like many things the start up costs are the highest. I have a RCBS JR3 press with dies from RCBS, Lee, Hornady and one or two others that I have picked up from various places. My question is powder. I currently have IMR 4064 for use with the following calibers. .222, .243, 7.62x54R, 8mm mauser, .35 Whelen and 45-70 for rifles and some Unique for .40 SW .357 .44mag & 7.62 x 25. I purchased the Lyman reloading manual which came highly recomended in some other posts. I intend to use the .222 and the .243 for ground hogs so I am more interested in accuracy. The .243, .35 whelen and the 45-70 are all H&R single shots. The .222 is an older Remington 788. The 7.62x54R is a 91/30 Mosin Nagant and the 8mm Mauser is a Yugo M48.
There have been some posts about the .35 Whelen not working with factory ammo so I haven't purchased any...just the brass etc to "roll my own" Same with the 45-70 but I want loads adequate for black bear. My last question is how can primers affect the load, especially if they are just large rifle primers etc. I do not understand why or how there could be a significant difference from one manufacturer to another.
Thanks in advance for your assistance.
