    Custom Dies for Custom chamber for custom rifle?

    Im currently building a 7 Rem Mag and finally have my machinist taking care of business after a long wait for everything to come in- #8 Shilen barrel, AICS 2.0 LH stock, Rem 700 LH action (i shoot right, but started loading left after hanging around too many BR shooters- its actually great!)...

    Re-chambering a semi with a tighter chamber

    Let me start with a story. Plenty of times I have taken my AR-10 out to 400-500 yards and with handloads, the gun performs just fine. Won't shoot bugholes, but will keep fist sized groups and definitely save your life if it ever needed to do so. Finally, I got to really "stretch" her out...

    Can't pick a chassis

    Currently piecing together all the stuff to finalize my 7mm Rem Mag build and still needing a chassis. Was originally going to use the TAC21 chassis until I called on friday and was told they had NO magazine that worked with the 7RM. Great. Here's my problem. I prefer a left handed bolt...

    Custom chamber/reamer

    Looking for recommendations on purchasing a custom reamer for my barrel blank. Would like to send in a "dummy" 7 Rem Mag with the 162 AMAX loaded at magazine length (with clearance built in for the length) and discuss throat lead in angle, throat tightness ect. Was considering Clymers- anyone...

    .458 SOCOM upper on AR-10B lower?

    Does anyone know if you could purchase a Armalite AR-10 Upper and re-barrel for the .458 socom? The rim diameter on the 458 is the same as the .308, so I assume the bolt carrier would be the same as the standard AR-10 right? Im trying to figure out the best way to build a socom upper for...

    Neck turning and chamber sizing

    Im building a custom 7 Rem Mag and want to really squeeze every drop of performance out of it, so I thought I would venture into the neck turning territory. I've been meaning to start neck turning anyway to get more consistent neck tension and avoid donuts anyway. My question is, what do I need...

    7mm barrel choices-

    Was thinking of a regular 6r Krieger barrel in 7mm for my 7 Rem Mag build but was curious about the 5r stuff only for the following: I assume accuracy between 5r and 6r is the same with no advantages to either. I guess that between 5r and 6r there is a slight FPS advantage that goes to...

    7mm Rem Mag parts/build list

    Decided to stick with a 7mm Rem Mag, so I have currently purchased- One brand new Left handed 7mm Rem Mag Remington 700 from Gander (Looked at it 5 times, negotiated 4 different times, finally got them to cut me a deal on it) TAC21 chassis, left handed long action (3lbs, 1 oz) Magpul PRS stock...

    Where to start with a custom rifle build?

    Well, just like the title says, I want a new rifle but don't know where to start. I thought I would build a custom rifle from the ground up (ive always wanted to do that) but have NO idea where to start! I know that I do want it to be a 7mm Rem Mag (love the ballistics, recoil is lighter...

    Suppressors Till hell freezes over?

    Well, I called the BATF today and found out my Form 4 was filed/completed August 15th. Hooray (or so I thought) I should be getting my suppressor in a few months! Wrong. I was told it will be NINE (9) MONTHS from the day it was processed until I will receive the paperwork from them...

    Savage 110BA vs ArmaLite AR30A1?

    I know this has probably been asked a thousand times, but I was curious if there are any advantages to buying the Savage over the ArmaLite? Personally, I've had shit luck with savage firearms in terms of accuracy (bought the woman a 7-08 that couldn't even hold 1 MOA. That's ridiculous. Yeah...

    First competition!

    Went out today and shot my first competition! It was a benchrest competition, and man did I show up WAY out of my league. Targets were mini-clays at 250 yards. That sounds easy until you realize how big a mini clay is and then the "oh shit" moment happens. Showed up with my trusty AR-10...

    Bullet seating issues

    I am currently working up a fresh load with a different powder than I normally use and did the usual ladder test, followed by another ladder test and finally, 3 loads in .1 increments (5 each) and had worse results. I narrowed it down to 39, 39.1 and 39.2 grains and all worked GREAT. Were...

    Shillen Semi Barrels

    Does anyone know if Shillen makes a match chamber for a AR-10 style barrel? My idiot light came on for me when I found specs for a NATO style chamber and realized my problem... I have a great barrel with a not so great chamber. My brass comes out pretty large... I use a FL die and measure...

    Deep Throat? (No, this isn't porn)

    How deep is the rifling supposed to be on a AR style weapon? I have called Armalite repeatedly to get answers, but finally just got "flagged" and they will only say that the information is "Proprietary". Well shit. On my rifle, the standard .308 is of course 2.800 OAL, however this places...

    Can't make heads or tails of my powder

    I recently tried some Varget loads (because I was out of H4895) and came up with some interesting results that I wanted to share, because I bet someone knows WHY my data is as follows: My setup is a 20" .308 AR-10 gas gun- now, I usually shoot 42.8 or 43.2 grains of H4895 depending on...

    Bought a Beta Chrony. Let the fun begin!

    So apparently, I have no idea how to get this thing to work. I've read the instructions cover to cover twice, and while I am using an air rifle that is supposed to shoot 450fps, the chrony reads... nothing. Im not a rocket scientist, but seriously, WTF? I have hung tape at 4" and 6"...

    Best MV from a gas gun?

    Well, I finally bought a Beta Chrony and will be going out to the range this weekend and was wondering, those of you with gas guns, how hot are you getting? Im shooting a .308 out of a 20" barrel, using Winchester brass and 175 SMK's, normal sizing, flash holes deburred, generous bullet...

    Why go heavy?

    Beyond the obvious ballistic coefficient increase, what would be the best reason to go from a bullet that works (a 175 SMK in my example) to say a 210 SMK (I have a 1:10 twist barrel, but it is a gas gun) if you already have great results with a 175? I know my rifle can push a 210, but didn't...

    Ruger SR22 Review-

    Not that the SR22 is "brand new" or anything, but thought I would share a quick problem/fix about the pistol. Bought a threaded version that I keep with my 22 suppressor (Zephyr XL, Thompson Machine- Great little suppressor, no first round pop) and shoot occasionally, mostly for pest control...
