we are about out of our 3 inch remington nitro mags...1 5/8 oz of buffered #4...i can still buy the stuff in 25rd boxes if i want..but my dad might shoot 3.5 inchers this year so i was thinking maybe try this magic heavy shot....my gun is a remington 870 express mag 3 inch turkey gun with a 21 inch barrel and a remington extended extra full turkey choke....it patterned GREAT with my previous load....i have 6 and my dad has 5 i think..but he will keep his and i dont have any to pattern with this year thats why i am thinking of switching...what shot size should i try for the best pattern the first time?? do i need a new choke for hevishot or will mine be fine?? i dont have much cash to work with at the time but i might before season so i dont know about getting a new choke....what do you guys think?? stay with my load or switch?? im sure with the pattern i threw with mine a turkey within 40yds is more than dead....thanx....
