I have been visiting this fine site for a couple of years now and this is my first post. I don't own a Marlin ( yet! ) but information I have gotten here regarding loading the .35 Remington cartridge has been great. I am currently feeding a 1954 vintage Remington 760 with the 180 speer and 44 grains of H335. I have chronographed the load at an honest 2400fps, and it is so accurate it is scary. It is "over maximum" but has proven completely safe in my rifle ( your results may vary so use extreme caution ) and is inspired by the excellent load data and penetration tests done by "35remington", one of the members here. The 180 grain speer penetrates like a freight train and hits like one too. Loaded to this velocity you have what I think of as a .35 caliber 300 savage. I believe it to be adequate for any game in North America inside 125 yards, and is most certainly a 200 yard deer cartridge. I have killed 4 deer with it and have been nothing but happy with the performance.
While I am on my rant I just want to say I simply LOVE the K3 Weaver scope with the POST RETICLE that sits on top of my 760. I find that it "settles" on the targed more naturally than a cross hair and doesn't amplify the waiver of the gun so much. It mystifies me why it is not still offered by all the manufacturers, but it gives me something to look for when I am wandering around at a gun show!
