Just found this thread;
Richard, give yourself a close evaluation of the type of matches, and where they are held (under what rules) to determine if your choice of 'platform' is the one you want to pursue.
I know Im not very likely to be entering NRA matches anymore, so as long as where I do go lets me use what I have, no worries. Yes, there are lots of things I would like to have, but Im not going to buy a (fill in the blank) to shoot one 'maybe' match.
I think a good 28" 45-70 would do as well for me as a 32", since I need a scope anyway so any sight radius advantage is moot, but if 'irons only' is the rule I would (pun intended) give it a shot.
