Thanks for your replies. I inherited some of these 320gr bullets from a family member. They are Cast Performance 320gr WLNGC. I only use N110 powder (as my reloading needs are very basic and I usually load the same round) and would like to find a nice load with that. Getting some other powder is not out of the question, but hopefully not neccessary.
Regarding the length, the crimp groove on these bullets is about .43" from the top, putting the oal at a little better than 1.7". This will easily fit in my raging bull.
I've been told that with the right charge, you can launch one of these bullets to over 1400fps. I am not expecting that N110 will do that, but would like to see what it can do.
Thanks for your input!
