My gun is a new Weatherby Vanguard sub-moa 7MM Rem Mag. The best that i could get with any of them was around 1 1/2".......terrible. My 300 Weatherby is .40 moa with 168 TTSX at 3300 FPS and running just short of standard COAL. I am going to take the 168's bergers back to around 3.350 and some at standard 3.290. I think these Weatherbys' like them shorter with all the free-bore???????? PS.....I did use different powder charges all the way up to max with each powder. The 160 accubonds with 66 grains fo H1000 at 3.360 shot around 1" and 3064 FPS. I also think the accubonds will do a little bit better pulled in??????? what do you guys think????????
Just a second....
You mentioned your rifle is new.
I do not want to scare you, but did you take everything out and put them back, put proper torque on screws, rings, base, rail, rifle screws.
Do not trust the sales person from the store, or the factory settings.
make sure the barell is freefloated, if you can insert a doubleside business card between barel and stock, all the way up to the action you are ok.
2nd think to do is give rifle 100-150round the tube(cheap ammo) , before you are starting to see tighter group.
By some reasons, this was happened with my Vanguard too.
