I got rained out two weeks ago, didn't go to the range last week. Yesterday, 3/23/05, it was nice and windy, with gusts, varying from bright sun to rain showers. About 84 degrees with excellent high humidity. Martini 30/30 bench rifle, Wolf No-Grease-Groove 213 grain bullets with two coats of Lee Liquid Alox, 12.5/AA#9, Remington 2 1/2 primers. One hundred yards, five-shot groups, one sighter, shoot two groups, clean.
Good bases 1.1", 1.6", 1.825" Average 1.508"
Filed bases, 45 degree at the edge 1.325", 1.65", 1.075" Average 1.35"
As an aside, I also tested 311299's from a "Beagled" mold, these averaged 1.069" for four groups with the same load.
The Wolf NGG bullet has always shot adequately if not as well as other bullets in this rifle, but leads about a foot up the barrel-hence the cleaning.
This is the third test, pictures are up on the Cast Boolits-Aimoo site of filed bases.
It starts to look like we can say that damage to the edges of bullet bases doesn't radically affect accuracy.
