Rem 700 in 6.5x55 w/ a McGowen 1:8.5 twist 28" heavy bull barrel

Put on a Vortex 6-24 PST in Mrad today. I had originally went with a 44 objective scope because I didn't think a 50mm scope would fit with my canted rail and truck axle of a barrel. But I did some measurements and the Vortex PST barely fits, as opposed to my leupold which does hit the barrel. It's close enough to where I cant even use the lens caps.

Previous:
Randall installed the barrel this past weekend and the stock required a good deal more opening up and I had to revisit 50grit (you called it, Whiterabbit).

Randall tipped me off on a couple mods I could do to my bolt to smooth out the action process - with a simple dremel+stone then a sanding wheel the motion is smooth as anything I've shot, requires only one finger up/back and forward/down.

I also figured while I was messing around with the bolt I'd tackle the knob project I've been wanting to do. It took awhile, but after lopping the small knob off I got the handle down to .312 for cutting and it came out pretty good, no casting holes or pitting. I had to Blue the arm just below the threads after to recover some sanded off spots.

I made the knob 1.45" long 1.05" dia tapered 20 degrees to 7/16" out of 660 bronze which I think goes well with my stock.

Ended up fitting perfect not hitting scope or the stock, also came out very shiny

Which I fixed by sand blasting, cuz shiny stuff is generally lame.

Love it, let us know how it shoots. Who makes the barrel and what contour is that?

Is this a M96? Is this for benchrest competition?

Nah, it's a remington 700 in 6.5 Swede built for long range precision work

I don't like the bolt knob. I think you would be better off with a blued steel knob. Aesthetically.

I won't judge the size and shape which I don't care for either, but seems entirely a matter of taste. So more power to ya there.

I think the bolt knob looks pretty legit on that rifle… I would love access to a lathe to turn my own.

I basically copied AR15Barrels (Randall)'s process, so I would ask him about it.

Bolt Tuning $40
This service is to re-work the cocking piece and bolt body to reduce the two bumps you feel when closing the bolt and to correct shroud misalignment which may cause cocking piece to drag in the receiver. The cause of the first bump is the cocking piece leaving the detent on the end of the bolt body. The cause of the second bump is the timing of the cocking piece hand-off from the bolt body to the sear in relation to where the lugs engage the helix in the front of the receiver. This service should not be performed if you are still planning to change triggers as each trigger module will need different setup to optimize the cocking piece travel. Have this done after you settle on the trigger you will be keeping in the rifle. This service is only available to walk-in customers as the receiver needs to be here to do the testing.

I like it.

I'm usually "walnut & blued steel" - a Remington 673 is about the most colorful rifle I own, but this looks good. Where did you get the stock? I've bought this style from Stockys and like it very much.

With the usual "if you ruin your gun it's your own fault" caveat can you give any more specific info on smoothing the bolt operation? Does one eliminate or reduce the "notch" in the back of the bolt and recontour the angle the cocking piece travels?

That definitely isn't a benchrest rifle.

Here's you gun's ugly brother. 26 inch Krieger in 6.5x284. Definitely lightened the stock up opening my barrel channel. First group with factory ammo wasn't bad either. The NF base and Sightron combo give me ~70 MOA of up from a 100 yard zero @32 power :-).

Very nice, I like it a lot.
I got about 16 mrad up from my 100 yard zero.

what kind of loads are you running? I'm shooting (forgive the pun) for 3000fps from a 140 berger VLD hunting bullet. With some favorable altitude (2300ft) and weather, I should stay supersonic to 1 mile - my goal.

Feel free to pm me for my recipe, it's above book max (which is for Swedish Mausers anyways)

But my components are
Tula large rifle primers
Norma Brass
RL 22 powder
140 Amax bullets @ 3.145" (.05-.08 onto the lands)

Traveling around 2920-2940fps the best I can assume thus far.

I've been using 140 VLD match as well with less favorable results, which this set-up and the last set-up as well. I've tried their recommended COAL tests, just havent gotten them to group quite like the amax's have - and i've put 10x more effort trying to get there vs the Amax.

If you have some 140 Amax and want to trade or are looking to buy some VLD's, I have about 450 left.
