Hey folks I dont know what I'm doing wrong, but I'm getting really fed up with my inconsistencies on my match ammo. So my match ammo is as follows: 243 Winchester Norma full length sized with Redding .269 bushing, trimmed to 2.040", neck turned to .015", primer pocket uniformed,annealed (after EVERY firing), vld chamfer and de burred. 107gr Sierra Match King. Base to ogive is 2.28" and I shit you not it shoots a .903" group at 300 yards. I use a RCBS comp seater that has been for what I think is hit or miss with accuracy of seating depths. Or perhaps I'm missing something here? Also this is NOT a compressed load; 39.2gr of H4350. I'm getting a few thousandths difference from base to ogive. 2.280= perfect; but I'm getting those odd balls that are 2.282-2.285.
