Question Regarding Tikka T3 300 Win Mag Load??

[Dobeman887]

I am currently trying to work up the best load possible for a Tikka T3 with a 1:11 twist. This is my neighbor's rifle that I "plan" on using to hunt free range Axis deer with in TX next year. So far I have only used Ramshot Hunter with 165gr and 180gr Barnes TTSX bullets. I have tried two different powder charges for each bullet. What I am finding, regardless of charge or bullet is that the first two shots are touching and the the third shot is about an inch or so high and right. I have shot on two different occasions with temps being around 50 degrees each time. Is the barrel heating up after the 2nd shot to cause that 3rd shot to do what it's doing? I was able to get some H4831sc and have loaded about 10 rounds but haven't tried them out yet. I usually am a big fan of Ramshot powders, but notice that Ramshot Hunter has dropped in price with the new "Grand" now out for significantly more. I suppose I could buy a pound and see how it does compared to Hunter. I plan on trying some ELD-X bullets as well. Any recommendations would be greatly appreciated.

With how many groups has this phenomenon repeated?

With how many groups has this phenomenon repeated?

Almost all 3 shot groups, and that is with a friend also shooting groups.

Not how many shots, in how many separate 3 shot groups did that phenomenon repeat? How many did it not repeat?

Shoot a 10 shot group and see how it goes. For hunting, about an inch high and right, I wouldn’t worry about. You have two in the same hole and the 3rd is one moa off, which isn’t going to be that big a deal under 400 yards.

Virtually every three shot group. We would go down and inspect the target for verification (probably about 5 minutes between shooting groups), and then shoot our next group of three. It just repeated I would say 9/10 times, not dependent on powder charge or bullet weight. The same pattern repeated for myself and my friend.
