I had my bench rifle in 6 br 1/8 twist rebarreled by Hart (ny) into a 6 Dasher 1/8 twist I bought 500 Berger Hybrids and spent last year trying to get it to shoot decent groups.I also tried 105 Lapua,& 105 a max, all at different seating depths. with not very good 300 yd performance Then I remembered how good the br shot the Berger vlds. so this year I bought 500 vld 105s all loads were with Varget powder (32.0 grns ) and using Eric Cortinas seating depth test the Dasher at .003 in to the rifleing is shooting sub .500 groups. some you win and most you dont
