Hey folks, like the title says I have a Interarms Mark X in 7mm Rem mag. I has a 24 inch barrel with a 1-10 twist. Lapped tally rings included. After digging around it looks like the B&C stock is original. I got it about 6 months ago and it had the original packaging grease in the action. Shows promise with 140 sgks and 154 sst, I've shot it less than 40 times. The trigger tuned up really nice. There is a little bit of speckling on top of the barrel, that's it.
I tried some 140 sgks with 4831 to sight in/break in the barrel a 10 shot group with cleaning in between rounds was about 0.5 vertical and 2 inches horizontal. That was before I adjusted the trigger, I attributed the heavy trigger and my "perfect" form to the horizontal stringing.
I worked up a load with 72.0 grains H1000 and 154 sst that shot about 0.9 inches at 3150. There were no pressure signs, i did increase the load from there and the group got a little bigger, velocity stayed the same until I had my first pressure sign and accuracy went to 3 inches. From memory, 71.3 to 72.0 were best accuracy with that bullet, powder, seating depth.
I had this rifle in .300 Win many years ago. Even the same stock. Excellent and accurate (.300 just wasn't the caliber for me in New England). I'd take one of these over a lot of rifles.
Free bump.
Work is what you do to finance your real life.....
If I didn't already have 2 7 mags, I'd be all over this rifle at this price. I own several Interarms Mark X's and I have never been anything but happy with them. No problems getting them to shoot way under an inch. They have taken a bunch of game. Phil
