MD Does stock design play a role in seeing the hit or not? I have ran more than 15000 rounds through a Herters 223 regular barrel and have no problem seeing my hits or misses at 400 yards. But with a Savage comp. stock of recent vintage it is a little harder to see. Both are sporter weight barrels and I shoot mostly 55 gr. bullets.
I think than most high volume shooters who reload shoot more Military brass than commercial. At least that is the case with the ones that I know. That would be the draw to me to go to the 20 Practical. For those that do not reload the cost would be much the same.
