I just bought a Marlin 1895gs about 4 months ago and it's a great rifle.Very easy to reload for as well,and the best part is that you can load them from mild to wild.I don't like the way a scope looks on a lever rifle ,so I up graded the sights to ghost ring sights from XS Sight Systems and still couldn't hit worth a damn (47 year old eyes).I had a Leupold scope that I had laying around and put that on the rifle and just went to sight it in last weekend.I got on the paper in 6 shots and then 3 shot groups in the bull at 50 yards ,with a 405gr Rem flat nose bullet and Varget powder.This coming weekend I'm going to try the rifle at the 100 yard line.
If your recoil shy it does kick like a bitch if you load your rounds hot,and the recoil pad leaves a lot to be desired.I put a Decelerator pad on it and soooooo much better.I have been shooting for many years and the 45/70 has become my favorite.I used to have a Marlin 336 in 35 rem that did nothing for me excitement wise ,the big bang of the 45/70 has that excitement.The 30/30 has cheaper ammo and the rifle is less expensive then the 1895 ,but the way I look at it is ONE OF the ARFCOM MOTTOS -BUY ONCE CRY ONCE. Also a lot of info on Marlin owners group for lever rifles,that might help you make up your mind.
P.S. got mine from buds $608.00 ,been seeing them at gun shows for $700 to $750.
