Sierra 90gr TGK and 748
#7
Berger 90 gr BT? If so it has a tangent ogive, which would make it more in line with the hdy 90 Eldx. G1 BC of 0.409 which is almost = to the eldx, 0.405 IIRC.
So, I would expect it to have a OAL max closer to an Eldx of 2.220-30 in most 6Arc chambers, which puts it about where you are.

The 90 TGK, otoh, has a sleeker, sharper ogive and 0.490 BC, in my chambers it maxes out more like 2.338, one chamber is 2.300 but it is much easier to seat out farther than the 90 BT mentioned. What I would be concerned about (although I hav not tested it to that length) is not having enough shank in the neck to stabilize the bullet during the firing. But if OP is having no issues with that then ok... I wouldn't be going there with my pipes however.
