model 70 ultimate shadow 7mm rem

I am having the darndest time to get my groups to come in on my reloading. and using a lot of imr with no luck even changing up the the bullet seating from 2thus to 20 thus of the lands and now I'm trying Hodges us 869 with the same problem does anybody have a pet load that they can share with me to help get my group in a little tighter my bullet weights of been varied from 154 to 160, 162 ,175 can't get to groups in any tighter than 3 inches at 100 yards. I don't know if you got anything to do with the harmonics of the gun with this 26 inch barrel.
my hunting trip is coming up so close so I'll just have to do with you 3 inches. I guess I'll just put a Woodstock on and a new trigger maybe that'll help Thanks.
