I am struggling to shoot better in the Swiss rifle matches at a local gun club. In these matches we shoot from the prone position out to 300 meters. My position is unstable. I can feel my elbows sliding across my shooting mat. Currently I am using a padded USMC-style cloth shooting jacket. I was given the opportunity to try another shooters jacket at the last match which made my position much more stable. I believe this other jacket was a Creedmore. My question concerns who I should buy my next jacket from. I see that Creedmoor offers some very nice coats starting at around $320 whereas Champion’s Choice have some that start around $125. I want a good jacket that will last me several years and am not averse to spending what I have to. I just don’t want to spend too much. What do you folks recommend?
