Ridgeline Defense RD-15 LPR

Brass looks fine but in my experience .223 doesn't show pressure signs until it does... So while I've had success loading .223 hot I try not to push the upper upper limits. Extra COAL helps a bit keeping pressure down.

Barrel shot well out of the gate, groups maybe tightened slightly but it was the speeding up I was watching for. The 200rd mark was more a cautionary move on my part less a hard number. Hell you may be good after 20 rounds.

Temp sensitivity sucks with Tac, like any ball powder

Yeah that's been my experience with the temp stuff. In NH it can be 95' in the summer and 0' in the winter, and I'm too lazy to have different loads for different seasons. My mk12 mod 1 runs about 2750 with 8208 so I figured this should run mid 2600s which is more than fine.

Agreed and would do the same. 8208 has been tough to find, great powder though. That 25.8gr load was the top end of my load development but seemed to shoot fine. Was pleasantly surprised at the lack of gas in the face and still proper ejection so they did a good job gassing the rifle even with a can on there.

I stocked up on like 10lbs of it over the summer when it hit stock again. Should last me a few thousand rounds.

May try StaBall again too, we will see.
