concerned about building a 7prc with tikka action

[V00D00]

i have a tikka action with a long bolt stop, and a hells canyon magazine that'll allow a 3.410 coal. I was originally going to build a 3wsm, but already own 2 so lately i started to lean towards 7prc. as i never played with one much. problem is im concerned that a 7prc wouldnt be that great in a tikka action being i can only get a 3.410 coal and saami off the top of my head is 3.290. i guess i should mention that i hand load. without grabbing a caliper and just looking at a calculator seems theres only 120 thousandths of play there. a penny for your thoughts..

I don't think it will be much of an issue unless you're one of those guys that insists on loading a few thousandths off the lands. I have a standard SAAMI chamber in my 7PRC. With the 160CX which is at the upper end of bullet lengths (1.624" if I recall) 3.460" OAL touches the lands. The berger 195 is a few thousandths longer than the 160CX and most everything else is shorter. But my rifle shoots very well with an OAL of 3.350" so I'm jumping 0.110" even though my AICS mag allows me to run anywhere I want.

I don't see why you would need to build one since they are now available from the factory. I would build a 6UM

Fun fact: one of my most accurate rifles is a wildcat on a short action shooting heavy bullets. I didnt want to waste a piece of brass to make a modified case so I just loaded to eight under mag length. For a good while I was kicking myself for not building it on a medium length action having the same thoughts as you. This is the only rifle Ive ever loaded for where I didnt measure to the lands and get anal on seating depth. There's no need to as it just plain works and I couldnt get tighter groups.

Moral of the story, just build it. You have plenty of room.
