7 PRC Load Development

[prcwv]

The slower the powder, the more you might lean to a magnum primer.

Copy that, it's a 18 inch barrel so I'm thinking a little faster burning maybe. Thinking of RL23 an 215m or 560

Just finished my lands testing with Berger 175 EH's.

Proof 22" CFB Suppressed

Peterson Brass 3x fired
CCI 250
65.4 gn N560

5 shot groups

-.040 OL
2857 fps
9 ES
3.9 SD
.393 MOA

-.050 off lands gave me
2859
13.3 ES
4.7 SD
.586 MOA - may have "pushed" one slightly


Hope this helps

I am shooting a Bergara Crest 7 PRC with 22" barrel.
ADG Brass
COL 3.300"
Fed GM210M
H1000 68.2 gr
Berger 175 EH

What altitude are you at to get those speeds out of a 22" barrel? Great numbers.

Seems like hornady fell way short of advertised. Been seeing more and more vids on youtube and reports of guys just not getting anywhere near 3000. You want that in a 22-24” barrel you may want the 28 nosler. But it seems pointless to waste that case in a short barrel

In my 7 prc with a 26” barrel, 68.7 grains H1000 with 180 vlds shoots 1/4” at 2960. Fed 210 or cci 250 shoot the same from testing.

What case are you using?

Almost identical to my nephews 7 mag load with 180Bergers and same fps in a 26" barrel i laod for

 

[rhovee]

Sounds about right. I think the volume between the 2 is very close.

I am in South Central Texas, just north of San Antonio. We are only 630 ft above sea level.

You're never going to get 3000fps with a 175-180g bullet from a 7 PRC with anything less than a 28-30" tube.

I haven't seen 1 rifle out of about 20, with 24-26" tubes get 3000fps...

Just chalk it up to another huge marketing scam by Hornady lol. Nothing magical about a 7 PRC.

Probably not magical....but it is a good replacement for the 7Rem mag. Just because the unneeded belt disappeared.

As someone that is looking at a 7mm factory rifle the 7PRC looks a good option. I'm waiting to see if Lapua make brass for it. If you are talking custom rifles then there are lots of options. For the average range shooter wanting a cost effective but accurate rifle the recent Hornady offering are pretty good.

I just don't get overly excited about it. I have a 7 Rem Mag and 7-300 Win Mag that do everything it does, and more, belt or not doesnt matter to me any.

Good for you! You have a good loading process. After 3 firings I can't get the case sized down enough to close the bolt smoothly. Belt is a problem with the two sons guns.

 

[kyotekiller25]

I've heard of some guys having that issue, but I've honestly never ran into it. I've got 9 firings on my 7-300 brass and no issues. Pockets are still tight and they feed like butter. It also shoots 1/4-1/3 MOA. 180g ELDMs at 3100. She's a hammer. Probably why I don't get to excited about many new 7mms. I've had most of them over the years, and the 7-300 is probably been my favorite by far.

Might be the RCBS dies they brought by. Lol

That very well could be the issue lol. I use Redding FL bushing sizer and a Forster ultra micrometer seater.

All my dies are Whidden. But my boys can buy their own brand!!!

 

[L.Sherm]

Guys complain about belted case sizing problems ive never had it, in my opinion its a die issue or really hot load and die won't size the brass back enough.
