At just over 9lbs it would have been a 'biter' Buckstix!
Good job adding that extra weigh & hence better balance.
Might have to watch that bolt handle too as it may give you a good smack on your hand upon firing.
As a further note an extra recoil bolt behind the rear of the magazine may help reduce the chance of a stock splitting from this heavy hitter!
Another great work horse for the collection mate, I think a lot including myself would like to see your loads on this one.
All the best for 2018
