7mm Rem mag load advice, updated

[montana_native]

My rebarrel job is supposed to be done this week. It's a Model 70 with a 26" Shilen Barrel, fluted number 5 contour. 1:9 twist

I have:

180 gr Bergers,
168 gr Bergers
160 gr Accubonds
Lots of H-1000
Lots of Retumbo
A little RL22
A little RL25
Lapua brass
CCI 250's

I'd like to load the Bergers to pack along incase I have the opportunity to take a long shot and have the Accubonds in the magazine for the closer stuff.

I found a thread stating RL22 and the Accubonds are a good mix. What about the Bergers? Just looking for a good starting point. Are the 180's going to be too heavy?

Thank you in advance.

Re: 7mm Rem mag load advice

RL-25 70grs gave me the speed and acuuracy with the 160 accubonds,3070fps with a Fed215 primer, accuracy was oustanding at 200 yards I got quite a few sub half inch groups when conditions were right!! Rl-22 gave me very good accuracy but the speed was 100fps slower and over book max in charge weight! And this is a 26inch Sauer 202 hunting rifle not a heavy barreled target gun.

with1t/9" berger 180rgs are the best if you have long freebore;i shot with my 7rem only bergers 168grs because my barrel is 1t / 9"1/4.

Re: 7mm Rem mag load advice

Thanks for the replies so far. I may try and pick up some more RL25 for the Accubonds.

Re: 7mm Rem mag load advice

my laredo did not have a break. it kicked too much with the 180's. i have had good results with re22 re19 h-4831. i would carry one weight/type bullet when hunting

I found the same thing. I shoot the exact same load. 70gr. of RL 25, 160 AB, Fed. 215. Shoots great. I get a little less velocity though. 3000 fps right on when averaged out.

I switched primers and tried the Br cci and that brought my speed downto 3022 avg of 7 shots and accuracy was just as good, but I could not get the speed thatI got with RL-25 with any of the other powders i tried which were, H-100, Rl-22 and IMR 7828. Rl-25 was the ticket and without pressure signs.

Re: 7mm Rem mag load advice

I have a 30" #7 SS in 7 Rem mag. Of all things a 1 in 7 twist...another story...

Am getting great results with 69 grs of RL-25 with both 180 Berger VLD thick and thin jacketed versions. Vel 3100. Custom reamer with bullets solidly into rifling...your results may vary...

Re: 7mm Rem mag load advice

OAL of loaded round with 180 Berger VLD is 3.515" with bullet into the rifling approx .015"
I have the luxury of building on a like new Mark X with a 375 H and H magazine box. Lots of room to chase the rifling over time and it fits and feeds great.

Hope you find a great load for you 7 mag.

Re: 7mm Rem mag load advice

Thanks for all of the info so far. I loaded up the 180's with H-1000 and the Accubonds with RL25.

I guess my barrel finished out at 27"

I hope to go shoot next weekend.

What is everyone using for a die set? I was thinking of ordering a Lee Collet. I currently have an olds RCBS two die set.

Re: 7mm Rem mag load advice

I'll be interested in your results. I've pulled an old S&W M1500 7mm RM out of the closet and figure on maybe working up some loads for it. I was going to try 150 E-Tips, 160 AB's and 180 Bergers and/or JLKs. I'm going to try Retumo and H1000.

Do you shoot at the Logan range? If so, it would be a pleasure to get together and shoot some, sometime.

Cheers,

MR

Re: 7mm Rem mag load advice

I had the lee collet die and it shaved too much brass off of the brass just above the belt. I bought a new set of RCBS dies and have been much happier.
