I have a 243 I built for f class( it was the cheapest way in since I already had everything but the new barrel) I have been using Rl26 and 105rdf's and getting 3300fps out of them easily but I'm having trouble with with my ES and maintaining good grouping over 80+ round course of fire

My original data showed an ES of 16 but the e targets last match were showing 200fps between high and low and the vertical seemed to agree. Any tips on 243 or Rl26 are appreciated.
