I have 3 #1s .300 win mag, 45-70, 375 H&H

my .300 win mag shoots under an inch easily (though I rarely shoot it)

my 45-70 with a particular 300gr HP Hornady bullet and 3031 at the book load for 1800fps shoots sub half inch groups....yea.....that’s what I said…...but my dealer measured them for me because I didn't believe it.

and my .375 H&H shoots an inch or better if you do your part....

the modern #1s seem to do really well...at least all of the ones I've had so far

I love em

-if someone explains how to do it on this forum I'll post pics of the .45-70 targets
