Any black powder patterning I do for the next few months will be done in 90 degrees and up. Will that make much difference next spring if I shoot at a gobbler when the temp may be in the 50s or 60s. I'm still intending to be 40 yards max with the black powder shotgun.
Your patterns will be significantly better patterns in the higher temps.
Thanks - I always see a lot of talk about temperature from those patterning the modern shells. I didn't know if that carried over to black powder also.
