I could not let the winter go by without a new build and the 222 Rem was it...sort of. I noted Lapua was making brass and I love their product. I hunt varmints and wind is a given, so speed is aiways needed. The 222 Rem's inherent accuracy is noted, but MV is not as I need, so I decided to modify the case with proven accuracy inhancing changes. Shoulder angle to 30° and body taper reduced by .010" at body/shoulder junction. New shoulder moved forward .055", shortening neck to .266". Case volumn is increased and I hoped with fast powder I could achieve 3500 fps with 52 gr bullets. Ordered reamer from JGS and dies from Whidden(based on reamer print). Kreiger heavy varmint, 14 twist finished at 30"...25fps/1". After fireforming brass, initially with COW...not adequate, so ff with full load. This gun is ACCURATE! H 4198 and IMR 4198 are excellent. Latest testing achieved 3500 fps and very small groups. Bolt lift easy and primers look unfired. Reloaded and primer pockets are still very tight. I will test some 55 gr bullets, just for fun, but damn, the 52s are lasers. The target is busy, but has loading data.
