This past year I went nuts with 45/70 & got a T/C Encore & an 1895 Marlin with 22" BBL &
worked relentlessly on a common accurate load for both & came up with IMR3031 at 1850 FPS,
only 50 FPS below book max using a Hornady 300 grain HP #4500.
During all the testing with other powders & various volumes I saw a repeating result that I have
heard of but never encountered before. The impacts would --string-- up or down almost in a straight
line.
Finally both rifles settled perfectly into the load mentioned. They stayed there with no problems
& I don't just guess at it, I made 20 more & fired 10 in each rifle for confirmation.
Now it is near deer season & I get my Marlin out. It shoots a perfect -string- straight up at 100
yards with the same original set up I had on it. Leupold scope & all. Now I think it's the scope
& swap it to a Nikon 3x9 BDC which has always been reliable & get the same results.
Any thoughts?
