[QUOTE="Swiftkill, post: 1695445, member: 104167"] 2950 is about max for a 180 from a 24" bbl, 3000 with a 26" bbl. 3100 with 215's ? That's cooking...literally. Where did you see that load info??? You should be more than happy with 3000 fps. (I'd be surprised to see that). Really, I think a 29" bbl is too long for that cartridge. I like 26" 27" may be max (without the brake). You can't turn a 3000 win mag into a RUM. Hodgdon lists 2950 as max with 61,000 psi with a 208 gr bullet and 24" bbl. AND that is a 81 gr Compressed load which means in your case you may nnot even be able to get that much powder in your case. You wont atuomatically get 30 fps per inch for the full 5 inches. There are diminishing returns. Back off and go for accuracy at a safe pressure. IMR IMR 8133 .308" 3.420" 74.5 2,680 47,500 PSI [B]81.0C 2,950 61,300 [/B] [/QUOTE]
