Here’s some load data from the last 6 or so years, that I selected based on good velocity, good accuracy, or use of a powder for which little data is available. Work up to these carefully only in a modern bolt action; they are maximum but with normal case life, extraction, bolt lift etc. Caution. Velocities are corrected to the muzzle. All primers are Rem 9 1/2 std primers, cases Hornady 22-250 necked up. Hope this maybe be of help to someone:
A) Hornady GMX 90 gr; land contact 2.606”; loads -.013 to-.020” A1) 37.5 grs Leverevolution (LVR), 3275 fps. Repeated 0.5” to 0.6” two shot groups at 100 yds. A2) 39.7 grs CFE223, 3310 fps. Repeated 0.4” two-shot groups.
B) Sierra 117 Pro Hunter, LC 2.479”, best results at -.020” to .025” B1) 42.2C grs IMR 7828 SSC, 2810 fps. 1” three shot groups. Extremely low std deviations of 0.1 to 0.2% B2) 33.5 grs IMR 4166, 2816 fps. Very clean, very low blast B3) 35.3 grs LVR, 0.10” to 0.50” two-shot groups
C) Hornady 117 gr Round Nose. LC 2.427, set at -.012 to -.015”. 38.0 grs Reloader 16, 2830 fps. Ultra clean. No extended accuracy series done yet.
In general I’ve found Leverevolution to be more accurate than the very similar CFE223 in most of my different rifles. In my pure varmint guns it will often beat CFE223 for velocity.
