Do I understand that your intention is to mill a 98 action to small ring dimentions? Consider the 7mm Ackley imp, 10 twist. It is usefull from groundhogs to moose. Low pressure low recoil.
The 98 is way stronger than the 96 sweedish which cocks on closing. A lot of 93s were converted to .308 dont know of any of them coming apart.
Just my opinion
