no a arms race every one is basicly shooting the same barrels- actions-cailbers - sights and loads.they went to the heavier barrels for less gun movement .even when I started chunk a 12 lb 40 cal was just wrong for shooting 60 yard chunk.i started with a 40 cal underhamer 1 inch barrel .it was worthless as a competitive chunk gun even 20 years ago.sure you make a couple good shots then welcome to the 10 shot string.take a good look at all the old chunk guns. they were long big heavy rascals. the only difference now is most are 1/2 stocked you did the same thing I did. made a very bad decision on what you wanted instead of what a winning chunk gun is. I take part of that back about 15 years ago a couple places
tried having 2 chunk classes at the same time and they had a under 12 lb class it failed quickly.what it turned out was guys using their hunting rifles or the small bench rifle they set up for 50 yard club matches. the good part is don't let it bother you.you have fun shooting your light 40 flinter -do it.you want a competitive chunk gun that's a different story
