This question is for serious handloaders and guys who shoot beyond 100 yards. What is the optimal bullet weight for resisting 10 to 15 mph wind gust when firing the .223/5.56 rifle described below?
I'm cutting sub moa groups, 3/4" at 100 and 1-3/4" at 300 with my new 20" FF heavy 1/8 twist, upper receiver for my AR.
The range safety who watched me firing at 300 last Sunday suggested I come out for the next 300 yard competition.
The groups described above were achieved with 55 grain .223 rem, both PMC Bronze and Federal Facotor reloads.
My concern is that the 55 grain is a light bullet and though last Sunday's winds were light, no more that 5 mph, 10 to 15 mph gusts are fairly common at Clark Rifles so I'm thinking a heavier load for competition might be prudent.
I'd like some suggestion so I can get back to the range and try some different brands in the suggested weights to see how they group for me.
I do not currently load .223/5.56 so please keep suggestions to commercaily available rounds.
