Well after attending a introduction class to F-Class, F-T/R and Wind Reading put on by Denys at Bayou Rifle I caught the itch to start entering some of the local matches. Thanks Denys for a great day! Question is will I be able to possibly come up w/ a load that will stay supersonic at 1000 yards w/ a 20" barrel? (Howa 1500 w/ 20" Barrel 1:10 twist). I know it's not optimal and I know shooting that distance w/ a 20" barrel is doable but any powder/bullet combo that will stay supersonic? I am still getting the hang of some of the software programs (JBM / GSEVEN). I will be doing the 300 yard and 600 yard matches but would really like to be able to safely compete in the 1000 yards as well. Should i just settle w/ just cutting my teeth w/ the 300 & 600 yard matches and wait till time to rebarrel? Thanks for any help and/or advise.
