I'm getting ready for next year with a little more emphasis on WFTF. Though I still plan on shooting in Hunter and Open some times.
I've made too many changes at times and then it's harder to evaluate what is actually helping. So I'm taking it a step at a time. OK - a couple steps at a time.
After the recent 2018 National match, the first thing I did was shorten the gun about 3" so that it would fit in a case that is legal on all airlines as checked baggage. I will be flying to a match at least one time next year. My rig was at 12 lbs originally, which is a good compromise for a 12fpe piston gun. I lost about 1 lb off the end of the muzzle when I shortened it and decided that the resulting 11 lb total weight was too low. I shot it just little bit that way. Lighter weight makes a piston gun harder to control and it's harder on scopes. I've seen piston FT guns weighing a lot more so I decided to add some extra weight during process. First I added an Anschutz style rail. The rail addition adds nothing by itself, but it gives me a convenient way to add other weights and accessories to test out.
The C-channel added about 4.2lb. and the ram mount about 1.5 lb. bringing the total to about 17 lb. I can swing the Ram mount forward and rest the flat channel on my knee for most shots, same way as I shot before. If I need some extra elevation for high angles or obscured targets, I can extend the hamster a few inches. That might also help on standing and kneeling shots.
Our club had an FT match in Cambria last Sunday. I tried the QB58 with just the C-channel (no hamster). I was also testing a new scope with higher mounts and new dope. I got the same score as I did the last time I shot in the old configuration on that same course. So far, so good. I'll add the hamster into the mix for the next match.
