Home Forums Hunting & Shooting Hunting Rifles 7 PRC Factory vs Handloads

Hmm wonder why IF they did change to wait 3 years.
Might want to confirm with Hornady, I would think they would have to send to saami for that but not sure.
I just looked on the saami sight and the 7PRC print still says .532-.533 and no revisions.
I've not heard anything of Hornady changing there PRC dimensions.

That's a good idea. I'll give Horn a ring - but won't be real surprised if I get someone who doesn't know what a reamer is.......

I hope you find one. Should make a helluva elk rifle.

I called Hornady and talked to a tech that seemed to know what he was talking about. He had no knowledge of Hornady changing the reamer dimensions. He did indicate he had seen cases of carbon buildup and a few lots of ammo that didn't meet pressure specs (on the high side). All told he indicated their pressure tested data with their amo should easily reach 2950 ish in 24 inch barrels all things being equal. I wonder if some if the rifle mfrs have a bit of freebore in their chambering causing pressure, therefore, velocity to drop?

Sounds like the guy at Fierce didn't know what he was talking about.
Better to get it straight from the Horses mouth.
I doudt Horny gives a [bleep] as long as there factory ammo works

This likely won't be the first or last time a manufacturer of ammo is way off on specs. Seems like Federal is running faster which in my little experience is always about right.

Anyone tried VV N165?

Bergara Wilderness Hunter Sniper Gray Cerakote Bolt Action Rifle - 7mm PRC - 22in. Hornady Brass, 175 ELD-X, 100 Yds. 3 shot groups.



65 gr RL 26, fed 215 primer, COAL 3.29. Above

66.5 gr, VV N165, Fed 215 Primer, COAL 3.29. Below

Both of them have some promise to em. Did you catch any speeds?

No, here in MN we had a heat wave today, 43 degrees. I ran out to the range over lunch hour. I knew the 26 would shoot well, had been shooting the N165 first. would like to tune it a little more. VV is $10.50a pound cheaper around here. Hopefully we will have another nice day sometime soon. Just picked up the rifle about a month ago.

Have you tried H1000 yet?

I know guys have had good luck with 565

Used Ramshot LRT to move 175 Hornady ELD-X's at 2929 fps from a 22" Bartlein barrel.

The load was shooting into the .4's at 100 yards from the bench.

Sadly, I didn't get a shot at game with it this year.

Guy

Will try that next.

I'm just starting to work with H1000 but haven't shot it
enough to form an opinion. Comparing to RL26 in the 7 SAUM and 7 PRC, initial impression is possibly a little better accuracy, and 100 fps less velocity at similar pressues.

ADG brass showed up just as we're packing for a trip to Hawaii. Threw together some H1000 loads with 180 ELDM's and ran out first thing yesterday (had to leave for airport at 2 pm).

Hornady data shows max with 180's at 67.4 gr H100 and 2900 fps in a 24" barreled. I shot 64, 65, 66 and 67 gr. Grouping really tightened up at 66 and 67 gr and 2797 and 2830 fps respectively. At 100 yds (I mislabeled as 175 ELDX):




New Arken EPL4 4-16 shot from initial bore sight without touching turrets to achieve zero. No clickers or stiff bolt lift, but very slight ejector marks at 67 gr, but damn this thing wants to shoot! I feel like 67.5 gr is doable and should be 2850'ish in a 22" barrel which jives with Hornady's data in a 24" barrel.

Will continue with RL26 in ADG brass in a couple weeks - aloha from the beach

Holy smokes. That gun does want to shoot! Thanks for posting that

Just got home from a muzzleloader hunt and the ADG brass was waiting on me. Want to do some measuring of this brass, fired brass from my rifle, and sized brass from the Redding FL sizing die. The fired brass from my rifle is every bit as hard to re-size as the once fired I picked up.

Wow. That’ll be hard to whoop!

Those are smoking groups! Please keep us updated on the progress.
