My new 450 build and first time out

Postby Eric H » Sat Feb 17, 2018 7:48 pm

Loaded up some 250 grain jacketed to break in barrel and get it on paper.
After I got home I cast up some 260 grain rnfp to try next.
My first shot using Mir 4227 left a bit of powder in the barrel and had very light recoil.
My next trip will involve a chronograph differ powders and bullets. Also trying out some Remington 7 1/2 primers. Just shooting with iron sight at fifty yards.had a couple groups that were very tight.
Using data from lyman 50th edition and hodgdons web sight.
I thought my 44 mag stuff was addictive, man this 450 is amazing.
I have a 20 inch 1/16 twist barrel from dead shot barrels. I polished my mill speck trigger and added a set screw. 4 pound crisp pull.
I will share more info when I hit the range.
