I'm looking at the Luppy Mark 4 scopes, probably in the 4.5-14 power range (although still considering the 6.5-20 power). I'm trying to figure out exactly what the differences are between the LR/T and PR models. 50mm vs 40mm objective...no problems with either. But what other differences are there? It looks like the turrets may be different between the two, but how? Is the LR/T really worth the extra $$? I will use the scope mainly for medium to long range hunting, but will ocassionally end up pushing timber where the ranges could be closer. Additionally I will use the rifle/scope for a lot of recreational target shooting/practice. Due to the remote area where I live, I will probably not get a chance to compare these scopes side-by-side, so I'm relying your opinions.
