I threaded my Marlin 336 30-30 1/2x28 for my SiCo Omega because the barrel wasn't thick enough for anything else without shortening the barrel and mag tube. It's only for hunting and low volume shooting at the range so it's fine. I would've preferred a larger thread size though. I have both .30 cal and 5.56 end caps and 5/8x24 and 1/2x28 direct thread mounts that I simply swap out between rifles. Only takes a minute with the tools provided.

Not only will you run the risk of concentric irregularities under high heat usage, but your chances of permanently locking two dissimilar metals together will increase exponentially.
Not worth my reputation If I weld a guy's $300 barrel to his $1000 can.
That's why you use a marine grade non-metallic high temp anti-seize on the threads like this: https://www.amazon.com/gp/product/B00JRT...pf_rd_i=desktop
