Deep cleaning the barrel may help with that new gun..if you havent done so already. Takes about 20-30 minutes. Inexpensive..hoppes, brush, rod, and a hand full of patches. Ive seen 20-40 pellet icreases in my guns doing this..Something ive noticed with new gun/choke combos is i can deep clean, then run a cheap box of shells through the gun, patch out, and then start with patterning the turkey loads and the patterns are much better. When I hunt with lead I shoot 35 or less. You should be in good shape at that yardage. You patterned at 42. You would be surprised if you pattern at 40. (Should be right at 100 @ 40) The pattern is detiorating quickly after 35. I killed three gobblers this year with HTL..15yds, 20yds, 36yds. Could have easily killed them with lead. Good luck to you and I hope you kill a biggun!
