I had a 1:8 22/243 for a while, so fussy on loads and hard on brass, split necks, accuracy was 1.5 MOA at best . Truflight Rechamberd it to 22-250ai all problems disappeared. Brass is on 5-6 firing no trimming required, no primer pocket stretch, no split necks. Shoots .3MOA with 80.5 bergers and .5 with the 80g eldm. Blows heads to smithereens, shot deer out to 350m in the crease DRT. A treat to shoot. Basically a ballistic twin to the 22creedmoor and been available since the 70’s as a wildcat.
