My pet load for Browning A-Bolt micro medallion youth rifle (20" BBL), Weatherby Camilla (20" BBL)and Fierce Firearms custom CT Edge (22" BBl) is 145 gr Barnes LRX ahead of 46 grs of RL-17, CCI BR-2 Primer and Lapua Brass. I get 2670 fps out of the Browning, 2700 in the Camilla and 2844 in the FF Custom. All less than 1 MOA (1/2 MOA in the FF) and very effective on game. Wife went three for three one shot kills on African Plains game off the sticks out to 150 yds. I had good luck with the little micro for years with 140 gr Nosler partition or SGK and 45.6 grs of I 4350...about the same velocity and results. The latter shoots lights out in my daughter-in-law's Rem 700 Walnut and Stainless in 24" BBl and she clocks right at 2900 fps in that longer pipe.
