Hi.
I use 78gr of retumbo and about same spreads as mentioned above. That is super accurate in my system.
BTW, has anyone tried the new 230gr berger match?
I was thinking to revisit the throat just a tad to make a dedicated chambering to take maximum advantage of the long action
but I am thinking the maximum COAL allowed might be the tactical 230gr. I am using AI magazines.
Another option would be to have a WSM super deep throated and in the long action too.
In this case the base of the bullet would be left flush at the shoulder level to accept maximum capacity.
I am sure someone has done this before so I was wondering about opinions.
Any thoughts?
