Remington 700 Sendero SF-II in 300 Win Mag

Today, I took my Sendero up to the range for a load workup and accuracy exercise. Last week I broke in the barrel with 70 rounds.

The load I was working up was a Sierra 168gr HPBT bullet over Re 22 powder in FC match cases. First a couple of pics of the gun.





The glass is a Leupold VX-3 3.5x10x40mm, the base is a NightForce 1-piece 20MOA.

For the weight (about 7lbs) the gun is quite comfortable to shoot even with hot commercial loads. The factory trigger, though a little heavy (5 lbs) breaks crisply and cleanly.

Yeah, yeah ... but is it accurate? Is it ever. I worked up weights from 75.0gr to 79.0gr, with a 0.5gr delta. Surprisingly, the two extremes were the most consist velocity-wise and accuracy wise. Here’s some target pics, shot at 100yds.


75.0gr Re 22 (3028+-29.8fps)


79.0gr Re 22 (3274+-9.6fps)

I think we have a winner. The horizontal spread (in the latter) can be explained by wind (it was quite gusty today).
