I use Fed 210 primers but some use magnums I have not had an issue. No particular case but I do make sure to keep the sub casings separate. Not sure why but I do. The Trail Boss because it is so flaky it fills up the case nicely at 10-11 grains. Just use a chrony and get below 1050fps or so and you are good to go. Just make sure you test your loads without the suppressor on and check for keyholing on the target.

Primer selection made a big difference for me. Winchester primers with 10.8 trailboss and 180 RN works the best for me by far. CCI mag and standard would open up the group considerably. Federal was ok, but winchester was better.

Brass brand did not make a huge impact, but neck sizing vs full length sizing did help a good bit.
