I’d stay with the same brass. Interesting enough, my rifle liked 42.5 – 42.6 with IMR4064, no supressor. Thanks for your effort. 🙂


Ohhhh Johnny!!! Very entertaining. I watched most of your reloading 101 25 part series and loved it! Your real, unrehearsed fun! One question… do you NOT show your face on purpose? Just wondering. I look forward to seeing more of your stuff.
