The 300 PRC is being pushed by many to compete with the 300 Norma. Fat chance, especially with the Norma having Lapua and Peterson brass.
I would agree with the success of the Creed , but there's Lapua brass for it selling like hot cakes. And it's not exactly sending heavy bullets at high velocity.
I'm not positive but I believe prime is using Hornady brass for this ammo.
I'm not sure about the Tempe sensitivity, just got started with RE 33. Velocity is there in spades !I may try some 230 Bergers in my Nosler, I tried the 230 SMKs with rl33 but they would not stabilize in my 10 twist so I gave up for now. I have not really seen a need for 230s after watching what the 215s do to game. How do you feel about the temp sensitivity of RL33 with your load?
One thing the 300 prc will have going for it is bullet selection. If they can get enough of them out there surely one of the good brass manufactures will make either 6.5 or 300 prc brass and it can be necked down or up from there.
Some of the worst brass I've ever used is hornady. I really wish they would get there crap together with regards to their brass. I've never met a fellow benchrest shooter that used hornady brass if they could help it. Only good thing about it is that its cheap
