Didn't go 20!

Nice bull, can't wait to shoot my 18" 7PRC this weekend for the first time.

I had the thought after this hunt I should’ve went 18” I absolutely love packing a compact rifle.

I’m super curious to hear about yours after you get it broke in.

Hopefully your handloading!

Will let you know. I'm unfortunately not a handloader yet. I do buy custom loaded ammo from Unknown Munitions. Breaking it in with factory ELD-X and ELD-M ammo tho first.

Handload? What load data have you had the best success with?

Any updates on how your 18 inch 7PRC is shooting?
Following because I'm looking at building one.

@Cbthomas

I just shot the 7prc for the first time this weekend. It was surprisingly soft shooting using an Ultra 9 suppressor. Total weight about 8.5 lbs.

Shooting Hornady Precision Hunter ammo, it averaged about 2630 fps during the break-in. I expect it to speed up over time for sure. But even at 2630, it is 1800 fps to 700 yards, which is exactly what I wanted.

Shorter is better.

I agree. For hunting ranges, there really is no “need” for longer barrels. Using 1800 FPS as minimum velocity at 5k elevation, my 16” 223 is good out to 700, my 16” 6 creed is good out to 700 and my 18” 6.5 PRC is good just past 1000. Just my opinion but longer barrels seem pointless to me, especially when you use a suppressor.

So I ordered a 7 PRC with intent of cutting to 20 inches...debating on 18 after this with my 7mm-08 an factory hornady ammo that's suppose to be 2950 which I'm gonna find someone with a 24 inch just to find out lol. My 7mm-08 is on 16.5 inches suppressed.

 

[prcwv]

Currently 22 inch barrel chronographed some factory 180 eld 3 shot average 2814. I'm going to handload some 162 eldm Peterson Brass. Pretty sure I'm gonna do 18 inches soon as I get a chance to get to my gunsmith. Weighs 6.5lbs now I absolutely did not like shooting it without a suppressor they have forever ruined me lol. Should be 8.5lbs with scope an suppressor.

Wow. That's quite a velocity difference. Box (assuming 24" barrel) says 2975, so you're giving up about 50fps per inch of barrel.

Yeah I chronographed with 22 inch barrel am was 2810 so 32.75 per inch of "real" velocity not box. Which I expected 25-35 from what I seen on my 7mm-08

 

[IrkedCitizen]

That speed is still plenty for practical hunting distances

Yeah I'm going to run 162s anyways I just wanted a baseline. Haven't made my mind up on which powder thinking 4831, Rl23 or 560

 

[IrkedCitizen]

Try all of them. If you can get 565 that could be a contender

I have it an can get more got 100 pieces of Peterson brass debating on large rifle match an magnum match may try both

Try out the 170 terminal ascents. You will prolly be 2840+ still - I'm right at 3k with a 22"
