7mm prc, how short is too short?

[IrkedCitizen]

Is that with factory ammo?

Looks like factory Federal 175gr eldx

Great velocity with factory ammo and 18 inch barrel.

Yes

if I wanted a 600 yard rifle for elk, is a 16 inch barrel too short ? I’m interested in cutting down my barrel from 22 inches and am currently running a banish backcountry can. I want to cut once and be done with it and not regret going not going shorter to start with.

You'd be at about 2800 ish with 16 inch with Federal from what I've chronographed

Any idea what energy retention would be ? I don’t hand load, and don’t have the bandwidth to hand load rn. I currently shoot factory hornady. But am interested in getting hand loads from choice, Pendleton, or copper creek.

At 600? Plenty... 2800 muzzle with the 175 eld-x will get you ~2K FPS and ~1700ish Ft. Lbs at 600 yards. That bullet will take you quite a bit further - using 1800 FPS for ELD-X expansion will get you 850+

Should be over 2400 fps an 2200 ftlb according to hornadys app if you getting 2800 at muzzle. Look on previous page I got velocity for federal with 18 inch barrel

That seems a bit quick... Running it through shooter at my elevation (3000) with tested and verified speeds and I don't even see 2400 at 600 yards with a muzzle of 2975...

You right my elevation got reset. Was sea level when I first looked

Higher elevation = less bullet drop/less speed loss due to less pressure - yeah something must have not been correct first calculation. Either way, the bullet is PLENTY fine at 600 with a muzzle of 2800

 

[prcwv]

Agreed, yeah app defaulted to Hornadys presets. Cause I was back an forth of what I wanted for a short barreled magnum. Knew if I got 2800 I'd be good. Now dealing with the clicker issue

 

[7LRM]

My 7 prc barrel is 26 in!

 

[prcwv]

Your on wrong thread lol

 

[Oregonhuntrboi]

Has anybody cut down a barrel and had accuracy issues afterwards ?

 

[RBHunter]

I am currently running a 22” barrel. Off the shelf Bergara. Handloads, 175 Berger over H1K sitting at 2850 fps. They are not close to hot at all. Odds are I will put a proof barrel on this summer. But will be going 20”. And if I can adjust my load and stay in the same speed range I’ll be happy. Puts the 1800 mark about 950 yards.

 

[primesuspectguides]

Sounds like a sweet build. I think you choose right. If you can get close to 2800, run it and enjoy killing stuff with a sweet stick! Who cares what others think.

Federal 175 ELD-X @2800fps breaking in my 18”

 

[Chase723]

I’ve got a 16” 7PRC. It’s a 16” Bartlein. Federal Premium w/ 175gr ELD-X is @ 2680fps suppressed. Shoots ~2/3 MOA for me at both 100 and 500. The range I’m at painted their steel black and I was using holdovers, so likely will shoot a little better if I dial and have a fixed point of aim. ES was 10 for 3 shots…small sample size but I only had 1 box. Barrel has 18 rounds down it so I anticipate it’ll probably speed up 20-50fps. Shoots well enough I ordered 500 rounds.

awesome setup…..any more thoughts since while breaking it in? I’m considering a 20” but 18” is looking more appealing.
