Closing on a NOGO is not the end of all things, closing on a FIELD yes. The biggest problem closing on a NOGO is if you are reloading ammo for several different guns, you need to keep the brass from the rifle that will close on a NG separate form brass from other guns with tighter chambers. Two barrels I have are a brand new BA barrel the other is a ELD? barrel I got for $40 from a guy that never installed it, I have tried 3 different bolts and they are all the pretty much the same, they will close on a NOGO [1.634"] but not on a 1.635" gauge. I would like to try them with a NIB bolt and see if the coating thickness is enough to make them pass the NOGO test, I have never used one so I don't know much about then them, do any body make longer bolts for the LR 308 to help with head space? eQ

It just makes it easier to hold the bolt, I use it with head space gauges. Like I said I don't like to use the carrier because you have no real feel when you just push the carrier in, with this I can feel the bolt turn and feel how tight or loose it is. I have a couple of cheaper LR 308 barrels that when checked bare [uninstalled] and turning the bolt by hand they will almost close on a NOGO [1.634"], but when installed and torqued to 40-60 foot pounds and checked with a carrier they will close on the NOGO but with my tool you would have to turn it pretty hard to get it to close on the NOGO. All testing done with a stripped bolt. eQ

I made a tool for checking Head Space with the barrel installed in the upper, I don't like using the bolt carrier to check head space because I think it gives to much mechanical advantage rotating the bolt. The tool I made is for AR 15's but it will work on LR 10/308's as well, its a little sloppy in a LR bolt but it works. the aluminum piece that goes in the cam pin hole is loose in the bigger bolt and the piece that centers the tool in the upper is also loose but you get a feel for it, If I can get access to a lathe I am going to make one for the LR 10 platform...

I have both of Brownells torque tools and they are little hard to work with because they are to short to clamp in a vise so I made a tool to hold them in the vise. I used a piece of 2" x 2" x1/4" square tube, drilled a hole for the torque to fit through one side and welded a 1/2" drive off of a couple of cheap Harbor Freight extensions, its not in the picture but I have since drilled and tapped the side for a 1/2"-13 set screw to hold the tool in place so it does not come out when you pull the upper of of it, I almost dropped a upper because it came out with the upper and I was not expecting it... eQ

I was born in Baker, OR in 1963, I guess the call it "Baker City" now. My Father was stationed at the Air Force base [821st AC & WS] that was there back then.

Hello my name is Casey, I live in a small town 40 miles out side of Las Vegas called Sandy Valley. I have built dozens of AR 15's and I am doing a few LR 10 builds now, I have already built a Very Heavy barrel one in .243 Win that I have not shot it yet, I need to load up some ammo for it. I am working on a couple of .308 shooters right now [a 16" carbine and a 20" rifle] and I am toying with the idea of building a 24" rifle in .300 Ruger Compact Magnum, I am just researching it for now, I don't know if it is possible or not its a pretty high pressure round [63,800 psi] I am using Noreen 80% lowers right now for my builds, they look like pretty nice lowers. I look forward to checking out this forum and gain some more info on the LR 10/308 platform. I earned the Earthquake handle because of my size [6'5"- 350 pounds] Casey/Earthquake

I am thinking about trying to build a LR 10 in .300 Ruger, It is a magnum round for sure. I want to have a 24" barrel with a +3" gas tube and adjustable gas block, I will use a Tubb's flat wire recoil spring with a hydraulic buffer and probably a weight in the bolt. KAK makes a upper in .300 WSM but I want to use a case with out a belt. The Ruger case head is .530, I was going to use a KAK Magnum bolt in a std bolt carrier. the .300 Ruger is a pretty high pressure round [around 63,800 psi] it will shoot 180gn bullets at 3000fps. I am looking for some one to make a barrel, I want it to have a .050" gas port that I will open up a couple of thousands at a time until the bolt will lock back and then open it up another .005" and start tuning with the adjustable gas block, I am worried about the barrel diameter at the barrel extension being to small [1.200"] to handle the pressure. has any body seen or done this kind of build? Thanks for any help Earthquake

I was looking info on a LR 10/308 build I am working on and found this site on a search engine. eQ
