Re: What we learned from our trainer in 2010....
1. a shorter barrel on a regular or pencil barreled rifle increases accurracy with not a big loss in FPS.
2. i'm more consistant and comfortable in the long run getting "straight behind the rifle".
3. better control of eye dominance - using both eyes open
4. homemade trigger job on trigger (pen spring)
5. a better judgement on wind, trajectory, and ranging.
6. better use of different shooting positions - sitting, prone, offhand, kneeling.
7. able to shoot support side more effectively, if need be.
8. when it comes to ammo sorting - rim thickness seems better at shorter ranges (50 yards), weighing more effective at 100 and beyond.
9. test a small lot of a new purchase of ammo before integrating it into your established stock - make sure it isn't defective.
10. lessons learned with the rimfire transfers very well over to centerfires, even more than i assumed.
