Looking to reload some 300acc

220 grain berry's

Curious to know what powder should I use and primer for the best results in a sig rattler suppressed.

5.5in barrel

Looking for some good data, please thank you

You have plenty of options - standard disclaimers apply - start at minimum charge, work your way up. If you do crimp the neck, go very light to avoid bullet separation. Since the bullets are copper plated, keep them at below 1200fps.

Best load I’ve found with Berry’s 220 Spire Point is 11.2 grains Accurate 1680, Winchester SR primers. I’m shooting them in a 12.5” SBR with a Banish 30. No chronograph data but it’s quiet and accurate. Got good results using CFE BLK also but not so with H110. It’ll depend on what load it likes the best so try a few different powders. Good luck.

Forgot to add to make sure you shoot a few of every different load and powder you try WITHOUT the suppressor to see if they are stabilizing before you shoot them with the suppressor. Look for key holing which means it is tumbling. Baffle strike will ruin your day.

what do you mean about the key holding?

When the bullet goes through the target instead of being a perfectly round hole you will see tears, rips or at worse where the bullet actually hit sideways.

Barrel lengths and twists have different effects on different types and weights of bullets. This can cause them to not leave the barrel stabilized. Sort of like the difference between a Tom Brady tight spiral pass and a Joe Biden limp wrist wobbling duck.

i shot some 220gr this weekend grouping were good! so hopefully it will be just as good when i shoot it again.

I set up a target at 5yds and one directly behind it at 10yds then shoot 5 rounds without the suppressor to see if I am getting good round holes with no rips or tears in both targets before I shoot them suppressed.

Hope you find some loads you like. I personally love the 220 as it packs a solid punch. Have fun and enjoy. 👍🏻

thanks for the tip. i def do not want a baffle strike so will make sure it is accurate shooting perfect holes
