I am truly sorry for having to start another thread on my load work for the 338Win Mag but Longranger has stolen my earlier thread.
I have been at the bench 4 straight days now with the 338Win Mag and my shoulder is beginning to notice the 338Win Mag that is banging on it :shock: :lol: :lol:
Something was nagging me concerning the 210gr Partition and not being able to find a combination that would work in my rifle. Now my rifle is a Ruger Mk II out of the box, no bedding or trigger work, not a bench gun for sure, so I was not expecting much but did want hunting accuracy. It is very picky when it comes to the 210gr Partition but I just could not stop until I at least knew it was hopeless and had tried every option I could imagine.
So I went back to an old Lyman load book and notice they were getting accuracy with Rem 9 1/2M primers and with the lighter bullets it was the 4350 class. So I loaded up IMR4350 using 74.5grs and H4350 with 73.5grs (these need to be worked up to). IMR4350 gave 2972fps which was outstanding but accuracy was not there just like before. So I though great, here I am and it is not getting any better.
But with H4350 I had a 7/8" group (might have been tighter but recoil was a factor being the last group after four days of abuse
) and it was moving at 2936fps which also good velocity. Yes, I finally have a hunting load with the bullet I wanted to use. Here is a picture of the group, chrony and the brass.
Three shot group 210gr Par, Rem brass, Rem 9 1/2M primer, 73.5grs H4350
Load work that led up to this initial post has been posted in the following posts for those who would like it kind of all together. Thank You, bullet
