Yep James good choice on the bullet weight. My success with the 6.5X47 has been with same bullet weights 120-130g. and H4350. One question about your target, could that middle load of 41.4 have been affected by wind? Seems odd that it would print an inch lower than the other two groups. Did you employ wind flags? Great shooting not trying to find any fault with it.You’ll have to do a bunch convincing to me and with proof why I should step up to the heavier Bullets....
This combo won me 2 shooter of the year awards in a club Benchrest match this past year down at Brocks Gap shooting against some of the best shooters around.
