Shot a whole box of .452 240xtp mags with good accuracy. Ive shot a few of the .429 240xtps, but accuracy wasnt quite as good as the .452s.
Best luck ive had were with the .452 300gr xtps.
On game performance has been solid, but nothing ive shot has been over 150lbs.
Out od curiosity i shot a group with .458 300grn nosler muzzleloader balistic tips in the black harvestors (support to use the orange .458 sabots for those). Accuracy was really good, but i had to completely clean the bore between shots or i couldnt load them. This makes me think that a tighter bore bullet fit helps on accuracy, im gonna order some orange sabots for next year and try those.
