Re: biggest of the SA\'s
I like to seat the bullet at the start of the boattail at the bottom of the neck. Anything further I think is too deep. Just my opinion. At this seating depth the 6.5 with a 142 MatchKing will not fit in a Wyatts extended box. Like Ric said a 190 MK in 300 will.
Why seat it so deep in the 6.5 WSM that you can't use the full potential of it. True, Ric's best accuracy with his 6.5 was around 3100, but I now a ouple of guys winning consistantly at 1000 yards pushing bullets at 3400.
The whole point is the 300 WSM barely fits into a SA. Winchester designed it for 150 gr bullets.
To equal 300 Win Mag performance modifications have to be made, ie the Wyatts mag box or go single shot.
The 6.5 WSM is a 1000 yard benchrest round (read single shot) It was not designed for a repeating varminter style rifle.
If he really wants a repeater in a SA he will have to use 120 or lighter bullets.
