Well, just to add a little update for now. I've just shot my first TR matches, 3 days and around 180 rounds total, and I think I'm hooked...
I had shot about 50 rounds prior going into it and changed a few things each day. After day 1 I could feel my left arm being quite sore, so I moved the hand stop ahead a little and made sure to better shoulder the rifle, also adjusted the butt length a bit and it made a good difference. First time plotting shots, with F-class I never bothered but I can now see that its helpful. I lost 2-3 points due to dialing the wrong way.
Day 1: (out of 50): 300M, 47-3(am), 45-1(pm) it has no cheek adjustment so I have to put way too much pressure at close range, better as the sights raise up further out. 500M, 48-3(am) 47-4(pm), 600M, 48-3(am), 49-2(pm)
Day 2: 500M 46-3, 600M, 48-7(lost the last 2, low left) 800M, 48-2, 49-5, 48-5. I was happy just to survive the heat... although I could only close the front iris to 3mm and at 800M I was still seeing the target frame a bit, very basic 18mm front sight with bubble inside(so useful). I'll try to take a look through those 30mm sights before I decide what exactly to buy, 22mm would probably be just fine.
After day 2 we had a wonderful dinner/awards given out at the Royal Artillery Park, being the oldest(1816) military Mess in Canada it was quite fitting with the shooting sports. We're very fortunate to have had this opportunity, great meal and everything.
As it turned out, although those 2 first days were horrible compared to the amazing shooters that were competing, (top shooter lost only 1 point out of 550), it was still enough to make it into the mini-palma match(coached match shot in string, all at 800M, out of 75, 75, 50) which was today. So after the dinner I came home to reload until 12:45am and today our Atlantic team of 12, 8TR and 4 F-class shooters, ended up winning vs New England at 2306-199 vs 2223-141. All the US shooters were fantastic, I think they had a great time as well and enjoyed our beautiful range. I ended up with 71-4, 67-6(ouch..) and 48-4. The conditions were changing fairly quickly, faster than I could get the shot off before they would change again, I did what I could though and really just had 1 shot I knew I screwed up bad and it was a low 3, 15th shot on 2nd match of the day.
So, in conclusion my goal now is to be set up properly for both F-class and TR and to gain the skills over time to be fairly competitive in both. Each have their challenges no question about it and I know what I can learn about technique in TR will help greatly with F-class. Just as some wind/mirage reading and reloading procedures I've been learning from F-class will help me with TR.
I'll see after December if I have time/$ to build a new rifle for the coming season and what exactly will happen, lots of other projects to keep throwing $ at right now.
thanks for the help/information, it'll be quite useful.
Also, to anyone wanting to try competition have it be F-class, TR, or anything else, please do. You don't need fancy rifles to start and there's many shooters willing to help.
I think a lot of F-class guys would really get a lot of fun out of TR too, I certainly did and plan to again.
