Asked this same question on another site but thought I'd also post it here for additional opinions.
"Yesterday while playing around with a new scope I put about 30 rounds of 250 grain casts down range with a 45 Colt H&R Buffalo Classic. The reloads were from a batch I put together a couple months ago, lubed with LLA and shot through the same gun on several occasions. Upon inspection after the shooting I noticed some very minor leading the first 4-5 inches into the bore. This has never happened before and a couple passes with a bore brush wrapped with chore girl cleared it right out. The only difference between previous shooting and yesterdays shooting was temperature. Previous shooting was with about 70+ degrees ambient temperature and yesterdays temperature was in the low 30's. So I'm wondering if temperature can affect the characteristics of the bullet or lube which could lead to possible leading. Doesn't make sense to me but I can't come up with any other solution as to why. Any thoughts from anyone?
Oh, the cast bullets were WW/AC at 1371 fps as registered by my chrony from the long gun if that helps."
