I sure do - I have a .308 - bought now both .338NM and .300NM - I will not lie, I cannot find ammo anywhere except .308. I went into it thinking that 338 and 300NM would become more and more available but it seems scarce everywhere, not to mention in my state where I cannot get shipments in from other places in the nation. Which simply just makes everything worse. In the end I need to shoot a ton of .308 for training so it is not a loss, but at barrel kit prices I might have gone a slightly different way if I had educated myself on just how scarce ammo would be.
I had done my research on reloading my own and at the time the costs were more than I wanted to invest, now I am thinking it is time to look at that multi thousand doller investment and even larger investment in time to offset my caliber decisions.
I did invest for the long term with the MRAD thou, so only a bump in the road, or a wait till I have more time to learn reloading for those.
