i have a rem1187 with a pure gold .670. i have been shooting the nitro blend. before that i shot the rem hevi-shot #5. this year i bought a box of the hevi-shot blend. i can't tell the difference from them and the nitro's. except the price. i like the hevi-shot because they help start the turkey shot revolution. believe the hype in the harder than lead. some cats will tell you they kill them with 2 3/4 low brass #6's. and you can, but why not take the best you can into the field. most people only get to shoot 1 or 2 times in a season so what is really $8 or $10 dollars.........tony
