[QUOTE="DJ Fergus, post: 1735956, member: 93895"] I know that no one wants to deal with the lapua bolt face but I've been very happy with my 300 Norma. I had a 300 win mag and nothing wrong with it but when I decided to step up, I wanted a significant step up in 30 cal. But I also understand that if a fellow already has a standard magnum bolt face on hand, the 300 Norma is not as easy as going to 300 prc or 30 nosler. I think the 300 prc is a great design and will be easier to load for than most saami chambered 300 win mags. I believe there is over optimism among the general potential buyers of the prc about significant velocity gain of the prc over the 300 win mag with the same powders & bullets loaded in both cartridges. Some gain, yes but it's hard for me to see 200fps gain over the win mag with same bullets & same powders. I would guess possible up to 100 fps gain on average if that much with all things being equal, barrel length, same bullets, same powders. This of course is all relative, and I won't debate an argument between the prc and win mag. The PRC is clearly a better designed case in factory form compared to the win mag but the win mag can be coaxed into hanging close with the prc. [/QUOTE]
