PH,
Congratulations to your brother. We look forward to a range report.
I've have very good luck with TAC.
52gr NCC seconds from the Shooters Proshop is my goto bullet for most applications. It's very accurate in my rifles and reasonably priced. I shoot them in 1 in 8 twists with no issues. 1 in 8 is a good all round twist for most users.
For primers, I shoot 450's with most of my ball powders, but I've found the S&B give better groups with TAC.
Third daughters rifle loves Benchmark behind the 40gr Nosler Flatbase bullets.
I've also shot a lot of H335 and BL(c)2 behind 50-55 gr bullets lit with CCI 450's. Both provide great results, but stay about a grain off max. It is a temp sensitive power, and prairie dogs like hot summer days.
