I just got back from the range sighting in my .45-70 that I had just installed a Leupold FX-II 2.5 Ultralight on, and using Speer 300 grain UniCors at 2200 fps, got groups from .970" to just over 1.5" at 100 yards. This bullet, at this speed, closely duplicates a .30-30's trajectory.
The Unicore is out and the Swirl is in....The Unicore is a much better bullet..Hope you stocked up on the Unicores,I did along with the 300 Nosler Partions,also replaced with a 300 ballistic tip.
