    How many rounds does an M need for break in per RA?

    I'm thinking 3-500. Don't remember exactly. I'm around 400 at this point. I'm going to get a couple of expensive match stuff and see if I can run on 1 or 2. My local shop sells the buffalo bore. Anybody tried this stuff?

    Mine took well under 100. Go by what the rifle tells you, not what a book says.

    Do you really think we want laws to be observed? We want them broken. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. When there aren't enough criminals, one makes them. One declares so many things to be crimes that it becomes impossible for men to live without breaking laws. Who wants law-abiding citizens? Pass the kind of laws that can’t be observed, enforced, or objectively interpreted - and you create a nation of law-breakers.

    I popped off 3 rounds of MFS 145gr just to test the cycle. On 2 it did not extract/feed. On three it threw the casings ~30 feet. Considering the nice work RWS Gunsmithing did on the Brux barrel, I don't really want to put steel jacketed projectiles through it.

    I haven't decided on optics yet, but once I do, and I get the time, I'll vid and excursion to a 1000 yrd range. So much to do, so little time.

    I've run MFS on 3. Failed to extract on 2. Not stuck, it just didn't make it back to the ejector, so it put the spent case back in the chamber.
