Havent seen any reviews or remarks about the nosler custom competition bullets and was thinking about trying them out... Sending them out of a 1:10 twist 20" barrel rem 700 aac-sd with manners tf3 stock and going with the heavy 190 grain. My initial feeling is to go with the sierras because they have always worked well for me but if nosler is very close to the same quality (less variation with weight and bearing surface) then I would go with nosler at 33 cents a piece.
