im shootin a .665 undertaker....right now shooting remington hevishot high velocity 6s i put 190 pellets one a 10x10 sheet of paper at 30 or 35yds...the choke made all the diffrence in my gun though...from the same .665 restriction on the factory choke to the underaker with any load was amazing to see the diffrence....i dont want it much tighter then it is....just nice and dense..get them flyers in the killzone...i fear missing at close range....i need some rifle sights for next year to go with the pistol grip stock im hoping to get.....im just looking for a load to replace the remingtons since they are done making them.....i heard envirometal was the same shot used in hevi 13s and remington loads....so its only logical to try them first.....and buying a 5 count box is alot cheaper then 30$ for 10 extended ranges that my gun might hate......i think it was 13$ for 5 hevi 13s...but i dont see them patterning POORLY since i have yet to fire a shell out of the undertaker that wasnt a turkey killing pattern...im not after distance..i dont field hunt or hunt where i can see much passed 40-50yds MAX...both the birds i killed were at 20 and 30yds....i rolled them both with a pretty SAD pattern that i thought was good back then lol.....i wouldnt even jumped on the whole hevi shot train...but picked up a box of rems and the undertaker last year DIRT CHEAP after season...now im impressed
