Figured to start a fun thread about some barrel burnin' .224" calibers, hoping they're well represented here??? After runnin' a .2223WSSM AR-15 a few years back, and .22-243Win for a spell afterward, finally decided to have a fast twist .22-243AI built. Its on a Rem700SA, #4 Brux 1:8tw @ 27", Micky Gamescout and Surgeon DBM. Had 'smith throat the chamber out long, a 75Amax is @ 2.780" to the lands, they feed smooth from detachable magazine. 50.0gr of H1000 pushes a moly'ed 75Amax right about 3600fps (3586fps velocity trued from drop data to 980yds). Forming loads with RL-22 run ~3300fps. Case capacity of the improved Lapua .243Win brass averages just over 55 grains of H2o... Shooting a fast twist .22 hotrod is like cheating! Very flat shooting, great wind bucking ability, and those Amaxs certainly are nasty game gitters. The long throat, heavy bullets and slow burn powder really seem to jive well together. With a few minor changes to original ergos (Seekins rail/rings, stock pack), this sucker is a real pisser to get behind! Smacks the crap outta coyotes, and 400yd woodchucks are almost too easy... Curious to see who else enjoys a .224 cal. hotrod? Swifts, .250s, x47Ls, TTHs, WSSMs, AI variants & other wildcats...whatcha got, what's your load, and how do ya like it???
