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.

James, Nice Group... Where did you get the targets you shot from? I need some different targets and like the ones in your pic.. I sure miss my .222 also. Shot really well with IMR 4198.These are from my 222 5 shot groups with Berger 52 grain bullets
