[QUOTE="highdrum, post: 2969985, member: 13732"] I don't think 568 will be a good choice in this case, I could be wrong. 568 per grain is a fair bit slower than N570. It's like a very low energy Retumbo, similar case fill but quite a bit slower. 568 was pretty anemic in my testing in a few overbore cartridges. The 338 long prc is not that overbore, more in line with a 300 wsm or 7 saum in case capacity to bore size. I think N555, RL23 N560, rl16 will likely be best, stabal65 may even be a good choice since you can pack a ton into it. I have 100pcs 300prc brass necked up to 338 and I do plan to build one eventually, I just need to find a 10tw blank, and get a reamer coming with 100k freebore for 250 Bergers. [/QUOTE]
