Over the past 40 years I have had many JM Marlin rifles in assorted calibers, I have had a few "Marlin jams" with JM stamped rifles and many with no problems at all.
My most recent 45-70 is an 1895 , it has a beautiful perfectly fitted oil finished walnut stock, the sights are straight and the blueing is perfect.
It is the first Remlin that I have ever bought, I was expecting some problems, after at least 100 rounds none have shown up.
I cycled it slow, then fast with a full mag and with only one loaded through the gate.
It has not failed any function test , I mounted a scope on it and shot a 1 inch group at 65 yds.
I then took a frozen melon out to two hundred yds. I was sighted in at 2 inches high at 100yds.
I held at the top of the melon and fired the 420 grain cast bullet, "POOF" , the range smelled like melon juice.
I think perhaps and I hope Remington has indeed turned the corner regarding the Marlin line of rifles.
