7-6.5 prc 4831sc starting charge

[EricCu]

I'm looking to test out 4831sc in my 7-6.5 prc and need a good area to start my testing. I'm running Berger 180 hybrids and 184 f-open out of a 32" Brux 9 twist barrel using adg brass. looking for a good area that won't over pressure. thanks

7-6.5 prc info needed

I just picked up a used f class rifle. It has a Borden brmxd with magnum bolt. I'm going with a 7-6.5 prc since it should perform close to the straight 284 that i already have. Which powders are working good in this cartridge with berger 180 & 184s? I see that h4350, h4831sc, n160 & n165 are...

I would also suggest that you ask “Willow” on this forum as he has had a lot experience with that powder as “Triple Nickel” (N555) is unobtainium in his local.

56-57gr should get you around 2850-2880 range. Start lower and work up. but this velocity range will keep pressure down.

thanks

If it’s any help I am using 56.5gr of 4831sc {Ar2213sc} behind Berger 184’s in a .280AI, 2’830fps.

I started at 54gn and went to 57 with 4831sc and a 32: barrel. Velocity was up to 2930 when I stopped. Didn’t get better groups than the N555 so I went with that instead. Mine was Lapua brass so I don’t know the difference in capacity for the ADG.

Thanks for all the help. I went out yesterday and 55.5g-56.6g grouped pretty good avg speeds from lowest charge to highest charge were 2871-2890. 2871-2880 got me 1.5"-5" height at 1k yards, width on the other hand was 4"-6" wide. Wind was 14mph with up to 30mph gust out of the SW and I had no flags to read wind. I'm going to make some more in that range and retest on a calm day to see if it can get tighter.

Looks like the 4831sc is working fine for you.


If you get a chance try the N555, it’s amazing as well in the 7-6.5, I’m running 57.7grs out of a 26” barrel and getting 2900fps with the 175gr Bergers/210M and 6.5 PRC Lapua brass necked up.
