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..
