The accuracy guys don't crimp their bullets, for my M1 I taper crimp just a wee bit. If I was loading SMK's or something, I wouldn't.
The CCI 200/250 is already a pretty hard cup, if you can't source #34's, just use the standard CCI's and make sure the primers are at least flush with the case, or better, slightly below.
At standard power levels (for example, my load of 47grn IMR4895) a slight difference in bullet seat depth won't make much difference. You are correct that possibly might affect accuracy, in that respect the only thing you could do is load two batches and see. I find it unlikely that any generic FMJ bullet would show a significant difference, but every rifle is different.
