No game taken with the LRAB yet but have worked up a150g LRAB load for Daughter #1's 1975 Rem M700 in .270 Win.

52.0g H100v gives 2910fps at the chrono (22" barrel) and when MPBR zeroed for a 6" target and 7000' altitude it retains 2234fps and 1662fpe at 600 yards with drop/drift at 52.6" and 15.5". Daughter #1 passed on her first elk opportunity ever last October because she wasn't comfortable with her .308/130g TTSX load at 476 yards, even though she shoots well at longer ranges. But hitting and killing are not the same and, in terms of energy, the 150g LRAB does at 600 yards what her .308/130g TTSX load does at 330 yards. I often use 1500fpe as a rule of thumb minimum for elk when comparing cartridge capability. Doing that, the .308/130g TTSX runs out of gas at 395 yards while the 150g LRAB is good to 710 yards. Calculated recoil in her rifles is 15.9 ft-lbs for the .308/130g load and under 17.7 for the 150g LRAB.

Accuracy with the 150g LRAB was outstanding during development with both IMR7977 and H100V. COL used was 3.467", 0.127" longer than SAAMI, but the cartridge fit the mag easily and the bullets were well of the lands. COL was determined by seating the bottom of the full diameter a caliber depth into the neck.a full diameter.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.
