Re: Wanting to build a rifle for F-Class
The Lapua 154 Scenar, Berger 155.5 Fullbore, and the Sierra 155 'Palma' Matchking are all good bullets, and will all fly just fine. I'm running the B155.5BTs for FCWC (actually, the whole US F/TR team is) and probably for FCNC in two months or so, but I also have a whole bunch of S155MKs on order for winter practice with my Palma rifle. They all work good - find which one works in your rifle, but don't spend too much time dithering over one having a fractionally higher BC or shooting a gnat's ***** tighter 3-shot group one time - get a load that shoots 1/2 minute or better, and go play in the wind. After you spend some time on the line in matches, you'll be able to better appreciate (and evaluate) your loads.
