Muzzle Velocity & SD

[Mchase]

So a week turned into a month at my smith, but finally got the 300WM back.

Tested out Barnes vor-tx 150’s and not sure what to think of these numbers. Isn’t the SD a little high?

Everybody seems to say they are looking for single digit sd. How does it shoot?

SD should improve after some more rounds go down the pipe.

In fact your SD is less than 1/2 of 1% of your average velocity. That's well below the error allowance of 1% that most chrono makers state in their owners' manuals, so understand that it could be off by 30+ fps faster or slower for each and every shot. I may use a chrono to figure muzzle velocity for my ballistic app, but beyond that, it's just numbers.

So, I put the chrono away several years back. Now, I just look at how things stack up on the target. Numbers can be fictitious, the target doesn't care, and it never lies.

It shot just a hair under 1moa. But I Still have the stock Remington Barrel and I think I should adjust The trigger a bit. It’s at 7oz. And surprised me a few times.

So all in all I think it’s gonna shoot pretty well.
