If the round starts faster, it ends up faster, no matter the bbl. length. You may get a lot more muzzle blast & flash though. I like the faster 185gr-200gr bullets in my OM. They still make 900fps from the shorter tube w/o the blast & recoil the smaller pistols can deliver.
I feel the NBT is at it's best when impact vel. is @ 2700fps or less. If yuo are sure your shots are going to be over 300, you should be ok. I would probably move to the NAB in your WSM. My last antelope was shot @ about 120yds using a 7mmDakota. I use the 160gr NP, planned for 400yd shot & just...
I can't think of a better replacement for anyones shotout .270 than a .280ai, go for it. I would use at elast a 23"bbl. if you are on the tall side, go 25" for a bit extra perf.
You should be fine w/ the NAB. I have found they retain about the same weight as the NP & expand a bit more but penetrate a bit less. I took my last antelope w/ a 160grNP @ 3250fps from my 7mmDakota. The range was a bit over 100yds & the round was thru the shoulder. Bang, flop & you could eat up...
Welcome to the .338-06 club! I built mine several years & several dozen animals ago. I love this round for general NA hunting & it's performed wonderfully in Africa for me too. The 210grNP seems just about made for this round. You can push it along @ 2750fps w/o bending anything & it kills very...
Guys, FWIW, if I had a perfectly good .280, which I do, I wouldn't bother rechambering to .280AI. You probably have a 22" bbl. so your perf. gain will be minimal, plus the extra cost of dies & the rechambering just doesn't pencil out. Now if you have a shot out .270 or such & want to rebarrel...
Maybe not ms, the R&D has already been done on the bonding process. I would think they could bring them in under the Swift. Drop the CTPG & save some money there.
Your 2 1/2" groups may just be you. H4831sc has been good for me w/ 140gr bullets, but you may want to try Imr4831 or RL19 or H4350. Every rifle is diff. I also like IMR7828 under the 140gr-160gr bullets. It's very uniform. I agree w/ the guys on the NBT, never been big on a bullet that explodes...
The problem w/ changing the NP design is R&D, plus adding a BT or PT will make it longer & change the basic flight qualities, which I find plenty accurate for 400yd shooting. It would be very simple to just apply the bonding process to the nose section of the std. NP. Simple, very effective &...
WHy would it be "damned expensive"? They lready have a bonding process, I would think it would be cheaper to manuf. than a Failsafe or PG. It would just add another step to the NP process & make a better bullet, IMO, than the PG. Come on Nosler guy!
Thanks for sharing. I am also a fan of the 160grNP/.280 combo. Mine is a M70, but I have a couple #1S, really like those rifles. I've been thinking of giving the 140gr NAB a try, but my .280 shoots the 160grNP so well I haven't wanted to switch. :grin:
Yeah Rogue, that's kind of my idea. I love the Partition, but could see the desirability & marketablity of a BonedPartition, The Bondition??????? Just the ticket for those realy fast movers up close.
Does Nosler ever intend to make a super partition by bonding the front lead core? Don't get me wrong, I love the original design, in fact it is all I currently hunt with (except my .404 for obvious reasons). Since you are making a bonded bullet anyway, why not a bonded partition? Super...
I think guys that hunt w/ match bullets are just rolling the dice. They may work great for 90% of your shots, after all, dead is dead right? The problem for me is that 10% of extreme failure, and when they fail they fail big.

Well you could dissect a round & weigh the charge, make sure it isn't an over load. I use a med. burner, starter load, for my .260AI & seat the bullet hard into the lands, no problems. I've fireformed w/o bullets before for my .404 jeffery also w/o problems (just to see if I could).
