Don't ask me why, but a guy I know used those 220 gain Speer flat points on moose and mostly lung shot them and they did not go far. He was firing them out of a .358 Norma, go figure. Skinner Sights are good stuff and he makes one with a cut out for use with medium height Talley rings so a guy could zero a scope in QD rings ad toss it in his pack when he wanted to just go with the peep.

I called Skinner Sights years ago and had him make me up one that was a little longer on the receiver and he engraved Skinner Alaskan on it, pretty cool stuff. It's on my Marlin 45-70 and I may order one of the ones cut for the Talley's and put my Leupold VX3 1.5-20x20 with the German #4 reticle on it. A quick and light weight set up.

Buffalo Bore loads those 220 grain Speers to 2,200 fps mv and when I called Tom the owner he said the loads were safe in any Marlin, no matter when it was made. That is a mighty potent load for any thing in North America.

Congrats on your new rifle!
