Ok I have a short barreled 243win I'm working on it's for my mom, she's fairly small so the rifle is a youth model. It's barrel length is 19" or so. What bullet and what powder would you recommend? I was thinking maybe h4350 or rl16 would be to slow of a burn for the shorter barrel was wondering if a faster powder would be a little better. It will be used for deer hunting not any long range either. What would you recommend for powder and bullets?
