6.5 Creedmoor +Peak Poll

[Ben Lamb]

Honestly, most modern guns can deal with excess pressure just fine. There are only really 2 ways to blow up guns/actions reliably:

1. Occlude the barrel somehow. Mud, 20 ga in a 12 ga, etc.
2. Use a radically wrong powder. Usually this is pistol powder in a rifle cartridge. H110 instead of H1000 and you are pulling the trigger on a pipe bomb....

It's not just the gun blowing up. It's the wear and tear on an action and bbl through excessive pressure, shorterning the life of the firearm and/or creating excessive headspace issues over time. You're also looking at other issues like pierced primers, increased potential for case-head separation, etc. The rush to increase velocity in existing cartridges just seems like a marketing-driven desire to get more of your money more than aything else.

The PRC family, as a comparison, was designed for the rifles they're going in - longer throats, chambered specifically for the cartridge. Those guns will all have shorter barrel life, but because they using brass cartridges, you'll likely see the problems faster if you handload/reload (loose primer pockets, incipient casehead sep, etc).

Agreed. 200-300 fps isn't gonna do anything from a success perspective. Gotta keep the gun nuts drugged up tho.

Always nice to have options but between the ammo I've currently got on hand and the fact that my Manbun and ELD-X's have killed everything I have pointed them at to date, I don't see me playing in the +Peak realm for a bit. I have really enjoyed carrying around a sub 6# shooter the last few years! (and that's with a VX-3HD 4.5-14x40mm on board and 5 rounds ready to roll)

Let's just reintroduce a 6th 30 cal pistol round and tell them it's the antidote to everything they dislike about their recoil heavy 9's.

For some perspective - bolt thrust is less from a 6.5 creed peak plus than a "hot rodded" 6.5 prc - so i wouldnt worry about blowing your gun up, or excessive wear on the action. The important math here is also showing that you can't do this Peak plus business with a fat case (pressure x area = force/thrust). Probably why 7 bc is standard dia like 308/.30-06 and not fat case like a magnum.

Of course assuming thats assuming the action between both has the same geometry. Notable exceptions might be things like rem model 7s and howa superlites though - that are scaled down. @Big Fin - what does howa say?

Barrel wear will be faster - also the case with the 6.5 prc. I dont think ill ever need it or that its really a big "gamechanger" - but nearly every recent improvement in bullet/ammo tech has been relatively small and fall into the same category.
