Anyone use Barnes X bullet,300gr 45?

[Harve Curry]

Thinking of making up a hunting load for my old Marlin relined to 45-70. It doesn't stabilize 405 gr bullets. But does well (1.5" at 100 yards) with the old 330gr Lyman mold I cast with. But I've seen these pure copper Barnes bullets kill and was thinking of getting a box to use on Elk. At a dollar a piece I won't have much to practice with.
My reloads will be limited to about 1700fps to 1800fps with a 300gr bullet.

Anyone have experience with the Barnes X bullet of 300 grains, .458"dia.?

Im in the same boat. Not sure which bullet to start with. Im starting to lean towards the Barnes original 300 grn
Might order some up right now
