I'll use the 125AB in my 30BR, but not in any cartridge I expect to shoot past 250yds.

This has me laughing!! LOL.....



Please enlighten me. I ran the numbers with a 6.5 130AB (JBM doesn't have the 129LR yet) at 3400 and .30 125BT (JBM doesn't have the 125AB yet)at your 3650. With 200yd zeros the 6.5 drops 29.0 and drifts 15.3 (10mph) at 500yds. The .30 drops 28.4 and drifts 20.4. The .30 cal bullet drifts about 30% more at 500. From where does your amusement come?
