Thats awesome guys!!!
Congrats to both of you.
I dont have very many rockchucks up here either. Theres only 2 places that I know of and 1 is off limits. The other spot is only out to 500 yards or so at most.
I would use the 105 amax myself for the expansion.
This is giving me the itch even more to find some 1K worthy loads for my 243 w/105 amax and my 264 w/140 amax.
The 7mms with 162g amax is awesome performer as well. I like the good old 7 RM. The Dakota would be good to if I was gonna build. Nothin wrong with the WSM, but I dont really like short/fat cartridges.
The 7mms will get you to 1500, you dont want or need the 338. To expensive and to much kick. Now if you wanna reach out beyone 1500, then yes, the big 338s are about the cheapest route to go.
Good luck rest of the year guys!!
