Looking for some advice based on personal experiences. My guns specifics are as follows: 6mm Dasher, Krieger 4 groove, 1:8 twist, .237 Bore, .107 FB finished at 28” using Lapua brass. Hoping to shoot some 1000 yard Benchrest matches this year, have only shot in one match to date and was fairly happy with the results. The gun seems to like Berger’s 105 VLD Hunting fairly well. Would like to try some customs to see if I am leaving anything on the table. Thanks in advance for your advice.
