Perhaps a year or more ago I loaded some .308's and there they sat in the box until last weekend. It was sunny, bright, little to no wind and according to some gun writers I should have never gotten the group I did. I was shooting a CZ 550 varmint which is a nicely done mauser 98 (some one once wrote that any Mauser won't shoot better than 3/4" at 100 yds.) I seated the bullet to the point of just touching the lands of the chamber which left the gas check, and a lube groove exposed to the powder and used no filler. I did not weight the bullets as I do with my win '85 in .32-40 and left the front 2 empty lube grooves exposed. The glass was a 6x-18 Leapold set at 18x and used CZ rings. The first seven shots measured .338 c-t-c with the eighth shot, that I admittedly pulled to the right making the group .459 c-t-c. The load was in brand new WW brass, 17.0 grs of 2400, a WLR primer (hand seated), and a SAECO (mold # 315) 175.5gr bullet sized to .311 (this means no sizing) made from ACWW with a hornady GC. The only brass prep that I did was to chamfer the flash holes. I shot several 3 and 5 shot groups of the one hole type and the last eight rounds were the group shown. On a parting note, these were just supposed to be spotters as I had just put the scope back on this rifle.
