we finally had a brake in the crappy iowa weather we've been having, so, yesterday i spent some time at the range with the wilkinsons in .577 that i cast up about a month ago. for those that don't know, they are 418grn and cast from pure lead. i dipped them in straight crisco due to the colder temps, and i shot them from my 3 band pedersoli enfield. the load was 65 grns of 3F Swiss.
i also chronographed the shots as well
here is a 5 shot string
some of these had a little less than perfect bases which i believe contributes to the velocity variations.
we have two targets, the first at 50yrds and the second at 100yrds. the conditions were 36degreesF, overcast with variable winds from the southeast.
