Went to a local club today. The temp overnight dipped into the high 20's. The temp when I was shooting was about 40. All the targets were kept in an unheated environment overnight. Got the best breaks with 1 oz of #8 with 17 gr Claydot, TGT 12 & a Cheddite primer. We were shooting singles only. The question is would this load be OK for short caps if the temp was @ 32 during competition. I'll be shooting registered this Sat. & it is expected to be colder. I have some loaders that are the same but use 17.5 grs Clay Dot.
