So I gave my Remington 700 5R Milspec to "Gunboy" last week to accurize and shorten it. Got it back today, after a few minor hiccups with the brake, and it turned out pretty good. The barrel was cut to about 19.5" and a Surefire 7.62 Brake was installed, making the barrel about 21" in length with the brake installed. Gunboy trued the action, lapped the bolt lugs, polished the chamber, and checked it over. I think it looks pretty good. Now if the Spruce Grive Range would just open up Rifle #1, #2 again, I'd be in business.

Out at the range today doing some work on my NR ACR, and put some more lead down on my 700 Shorty:

Sweet...be sure to post a range report, interested to hear details of the brake....I want to put one on my 5R and everyone laughs at me....I like being able to see my hits like I can with the 223.
 
Any concerns about loss of velocity/accuracy with the shorter barrel?

Did you do any load work on the barrel before you shortened it? You can make a before/after comparison on how barrel length effects charge/bullet weight to keep velocities up.

just saying.... :)

Very nice though.
 
Nice rifle. I am also waiting on Spruce Grove. Apparently all of the modifications have been done to the rifle range. They are awaiting CFO inspection and approval but they seem to be taking their sweet a$$ time.
 
Varget work pretty good at around 44to 45 grain, for my 20 inchs barrel 168grain BTHP will give 2650to 2700 fps.
 
I've finally started to look into buying myself such a rifle. Been mostly a shotgun/black rifle kinda guy. This just motivated me a bit more to get my butt out there and buy myself one...gorgeous
 
I put 40 rds of FGMM through the shorty 5R today at Genesee Range at 100 yds. I shot a 5 rd C to C group measuring 0.46" with 175 FGMM and several sub MOA groups with 168 FGMM off a crappy bench with no bag. I have not shot this rifle in 6 months, so I was a little rusty. Its showing great potential and gathered a lot of attention. I just need to adjust the brake angle slightly and shoot it from the prone. I'm sure it will shoot sub 1/2" groups with FGMM and some practice and maybe better with my hand loads. The SF brake provided fairly good recoil reduction, but was not aligned perfectly, so the rifle was pushing left after every shot. I fixed it tonight, so I'll try it again next weekend and see what I can do.

I though the angle was perfect, look pretty straight to me. maybe need minor adjustment.

It just needed a 1/4" of turn, which I fixed when I got home. The main diversion nozzle was at the Three O'clock position, instead of the One to Two O'clock position. It looked straight from the top, as the surefire emblem was exactly centered for the gun, however the emblem was not exactly centered on the brake. The reference notch on the bottom, was about a 1/4" off center.

"An effective muzzle brake design has expansion chambers, gas ports/diversion nozzles and perpendicular baffles. Muzzle climb tend to be in the 1-2 o’clock range, and SureFire’s larger 1-2 o’clock gas port/ports are tuned to reduce this, and the perpendicular baffles catches muzzle gas and pulls the rifle forward hence negating a good percentage of recoil impulse."

The result was the gas diversion nozzles pushing the barrel slightly to the left when fired. With the ports in the correct position it will force the barrel directly down. Accuracy was not effected, just the follow-up shots took longer, as the gun was pushed to the L. of the point of aim after every shot.

I got similar build on the go, a pierce action with a 27" shilen barrel to put in a 2.0 chassis. So here's the question does a muzzle break make that much of recoil reduction, would you recommend it? The smallest chamber I've used a break on was a 300wby

I'm really not an expert on brakes, as I'm kind of new to the concept. I just put a SF brake on my 5.56 mm and it really helped with muzzle climb/hop, however recoil was never really an issue without it. I had not fired my .308 for some time, so its hard to give an entirely objective opinion on the recoil reduction with this brake. Again, recoil was never really an issue with my .308 at 24", but the muzzle did hop a bit off the bipod when I fired it without the brake. There definitely is some recoil reduction with this brake installed, I just can't say how much. The muzzle also stays in position better for follow up shots, which I imagine will be even better now that I've adjusted the brake. That's all I really can say, however I would agree that a muzzle brake on a .308 is not quite the advantage that it would be on .300, .338, or .50.
