Utilizing 307 load data for 308 cases?
I was figuring out what components i needed to buy and I realized I load more often for my 308 than I do for my 30-30, as I went through my stuff and noticed I have a bunch of bullets for my 30-30 I have 200 winchester 150 grain power points and 200 sierra 150 grain pro hunters. I know the 307 win is basically a rimmed 308 win and the data is very similar, but i also noticed the 307 win uses the same style bullets as a 30-30. What I'm getting at here is Im wanting to use 307 win load data with these extra 30-30 bullets in my 308. Now my question is are there any stipulations that would keep me from doing this? I already planned on using H4895 powder since I already use it for reduced loads in my 308 and I figure it would help lower the possibility of under charging my loads. My other question is should I use 307 win COL's or 308 win COL's?? thanks in advance
