Have a Montana 1999 in 7mm Rem Mag, 26 inch barrel. Which of the two cartridges below would you rechamber to and why? Which would have better resale? This is just a for fun project, I'll likely build it and play with it at the range then let loose of it in a year or two.
28 Nosler: Requires changing the cartridge follower and potentially opening up the magazine lips to feed properly. 3 grains more powder, miniscule velocity advantage, one less cartridge storage capacity. Appears to be a more popular cartridge with better availability of ammunition currently.
7mm STW: Requires changing cartridge follower, modifying the magazine well (Easy on a Montana 1999, just remove the spacer)
Thanks!
