A very wet soggy afternoon at the range.
The reason for these groups looking a little ragged is because there was at least an inch worth of targets stapled on top of each other and they were soaking wet! I shot the 204, 17 RFB, and the 223 WSSM. The 40 grainers out of the WSSM made some huge splatter holes!
On to the keeper loads for the 204.
These are all 3 shot 100 yard groups. BL-C(2) / CCI 450 / COL 2.26 / 35 Grain Bergers (WS2 Coated) / Nosler Brass
Here is one of the WSSM groups. It is a Winchester Model 70 with a 22 inch pencil barrel. Muzzle blast is horrendous! One of two things will happen with this rifle, it will either get a 26" varmint contour barrel or it will be re-chambered/re-barreled into a "20 Vaporizer".
Notice the tears around the bullet holes. That area was all pushed back out towards the front of the target.
edit: The 204 groups are with Nosler brass.
