I checked my twist,and it is 1-9.5,and I can't see anything wrong with the crown.I have read that some rifles won't shoot boatails good even with proper twist, If this is true then I have one.I placed an order for several boxes of different caliber bullets with Mid-South and the 130s that I was going to order were on back order,so I bought a couple boxes of 145 gr Speer HotCor,and I am glad I did,it groups them about an inch at 100 yards, which is plenty good enough for my needs for this rifle.I expect I could do better with more experiments with loads,but I am satisfied enough .Thanks for the good advise folks.
