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.

I think it's cool and makes a lot of sense to introduce in the 6.5 creedmoor case. There are two primary things I see as possible down sides:
1. Exposure to higher odds of piercing primers - i believe the harder case heads/primer pockets will mitigate some of this but not all? It's a question ive posed to others and haven't gotten 100% answers on.
2. Bolt thrust seems to be a non issue if everything is clean and dry and the case grips the chamber walls. What about when things are soaking wet? Pretty easy to get excessive bolt thrust with sub 60k PSI loads in brass cases when ammo is wet, what does that look like at 80k PSI?

6.5 creed is pretty ho-hum on velocity with heavy for caliber bullets, espeically out of shorter barrels. This gives the guys who have a short/suppressed creedmoor a little more juice if they want it without requiring a full committment to more expensive, higher recoiling, and shorter barrel life chamberings like a PRC.

I guess new rounds and pushing the pressure limits can be interesting. But, really , after the trigger is squeezed… will the deer be any deader that if shot with a .270 Win ?

I think that the biggest plus and the selling point of the peak+ is the migration to shorter barrels and suppressors.
So the peak cases give you the same performance in an 16"-18" as a gun with a 22"-24" barrel with regular ammo.

As for wear and tear who cares if it's in you hunting rifle? I guess if it's you only gun it make a difference but my. Short barreled hunting rifle is not a gun I'm putting hundreds of rounds through each year. So i think 20 to 30 rounds a year isn't going to really make a big difference.

Lowest tier Savage 6.5 + 143 eld-x was sub MOA, first factory ammo I tested. It is easy to overcomplicate. Some really enjoy the tiny adjustments of handholding - I’ll never understand why, but whatever floats your boat.

Glock 7.62x25 Tokarev, anyone?

Wonder what the price will be when it hits the shelves? Creedmoor is an accurate round and very popular in the past 20 years. Found the 2 reasons to market this plus peak. .308 rounds out of a 300 weatherby beats the 308 by 500 fps but cost more than double the price and the old 308 will do the job fine. Keep your shots at reasonable distances.

I see this NOT as an everyday everything round. But as a round when you could use some extra horsepower. For example taking an elk size critter at 500 yards. I reload my own and am quite content with standard creed ballistics for most of my uses, but see this as an excellent potential option when I might wish to stretch the standard creed capabilities, as in a potential 500 yard shot at a big bull. I do not care to shoot past that yardage at live animals. I prefer to stalk closer and have been quite successful at that.
