The problem is not the number of shot during a match (often 3 x (15 shots + 2 sighters in 17 minutes)) but the fact that I often shot 75 rounds in 1 day and that even at a slow fire rate the barrel gets really hot after 5 shots! Remember that 270WSM accurate, 1/2 MOA or better at long range, barrel life is 750-1000 rounds.
Another larger issue is recoil/blast which degrades my accuracy after 5-10 shots fired from a 13.5lbs rifle. My groups go from 5 shots 1/2 MOA to 5 shots 3/4 - 1 MOA! This never happens with a similar weight 243 Win driving a 105gr VLD at 3000fps or a 223 Rem driving a 73gr VLD at 2900fps.
The F-Open class is a race between 7WSM, 284Win, 300WSM and other 7mm Wildcat magnums (the biggest issues here is performance and barrel life).
The only inexpensive way to shoot F-Class competively is F-TR Class in 223 Rem or 308 Win.
