It can be an issue using neck sized brass that was fired in a different rifle. Easy enough to find out - before doing anything more, try to chamber your prepared brass into the rifle that you plan to fire it in - one case at a time, every case - no primer, powder or bullet. Just because the two are both chambered in 308 does not mean that the fired brass will be inter-changable - if they were full length sized, yes, but neck sized only and not touching the shoulders, they are now "fire formed" for your Axis, and may or may not fit into your Remington. And vice-versa - with neck sizing only, you would be quite lucky to have brass fired in your Remington to fit into your Axis. Not counting wear or lug setback, there is often .004" from GO Gauge to NOGO Gauge, (1.630", 1.634") and when new, both rifles could have been correctly anywhere between those dimensions. Absolute maximum SAAMI length for a 308 Win chamber is .010" longer (1.640") than a GO gauge. SAAMI cartridge and chamber drawings readily available on the Internet - those headspace dimensions are from the case head to a specified point along the case's (or chamber's) shoulder face - not to the case mouth, not to shoulder, not to base of neck.
