    Gunsmithing Bull Barrel Brakes?

    I'll have my new 1.24" Super Beast brakes done next week but they are only in 5 ports for the big stuff. I maxed out the port size so you can turn them down though. I was looking for absolute max recoil reduction and I doubt anything will be any better but I'll test them against the Terminator...

    Gunsmithing 30 cal brake for 6.5 will it matter?

    I have self timed 2 piece brakes in M18x1.5 that I can open to any caliber you want.

    300 NORMA MAG ?

    A 300 Norma is basically a 300 Weatherby, 300 Jarrett, 30-8mm, etc. There isn't 3 grains of difference between them. Barrel life will be short if you run it hot and fast or upwards of 1500 rounds if your nice to it.

    300 NORMA MAG ?

    Bjay and I both got our dies. I also got my 30-338 Lapua Imp chambered last Sunday and fireformed 10 rounds today. I really don't want to waste much barrel life fireforming so I'll probably only do 20 rounds to see if it shoots and then rechamber a Remington factory barrel to form brass in if it...

    Gunsmithing 300 norma vs 300 hulk

    Sounds like if your OAL came in at 3.62" with my reamer you have your answer, .235".

    300 NORMA MAG ?

    My throat is .235" but it was set up to be between the 215's and 230's so I could shoot either if one or the other didn't shoot. Bjay's would be better for shooting straight 230's but .021" isn't much. My shoulder dimension is straight from a 338 Norma.

    300 NORMA MAG ?

    You'd probably gain 30-35fps/inch up to 32-33" and then it would probably drop off a bit after that. 33" would most likely get you 90-100fps over a 30" barrel. I'll have a better idea about fps and barrel length after I get my 30-338 Lapua Imp. done as I know what others are getting with slower...

    Gunsmithing Possible to cut this barrel?

    On a .308 you's probably only lose 25-35fps/inch not 100fps. As the powder capacity increases compared to the bore size the more you lose in velocity per inch.

    300 NORMA MAG ?

    I personally think you will give up accuracy and the barrel life will probably go down 150-200 rounds. Guns are no different than cars......if you want to have one of the fastest it's gonna cost you. If the accuracy is too far off I'll set it back and do another Norma Imp. with the barrel.

    300 NORMA MAG ?

    I got 3075fps with R-33 and a 230 Berger in a 30" Bartlein 4 groove. I'm pretty sure my barrel is slow or so it seems to me. My improved version is 110.3 grains if I remember right and a standard is 103.5. I would think I'd see more velocity then that seeing as how guys are getting near 3k out...

    300 NORMA MAG ?

    There isn't enough case capacity there without a hybrid throat like what Defensive Edge is using in their +P. You can do it with a 30-338 Lapua Imp fairly easily using a longer barrel.

    How old when you first broke 1000 yds?

    I was 21 and that was 22 years ago.

    300 NORMA MAG ?

    I ran 88 and 89grs with 230's through my 30-338 Norma Imp today (35* shoulder based on 338 Norma shoulder dimensions) , which was too low of charges, but the 89gr load shot a 3 shot group that was .120". The velocity was only 3000fps. I'll load 90-92 or 93 and see what I get next. 86grs of VV...

    Gunsmithing My 300-338 Lapua Magnum Project

    It has a caliber worth of neck length and a 35 degree shoulder. I can't remember what I spec'd for shoulder diameter but it didn't have a whole lot of taper. I was using WC872 for powder and about 128-130 grains of it. I think I was shooting 210gr Bergers 3650fps, 185 Bergers at 3800fps, and...

    Gunsmithing My 300-338 Lapua Magnum Project

    I have a .30-.378IMP. that does 4000+ FPS with 150 Ballistic Tips in a 30" Hart 10 twist barrel. I'd say with a 17" twist, 25gr lighter bullet, and 2" more barrel you should hit your goal. I'd do a improved version if it was me though.

    Gunsmithing 300 norma vs 300 hulk

    I would ditch the 240 idea too. If you make the throat too long and it doesn't like big bullets your done because the lighter ones won't usually like the big jump. BTW Sierra list the 240 at .711 BC.

    Gunsmithing Muzzle Brake Thread Size

    The odds of a brake being out of alignment with the bore will go up with a clamp on compared to a brake that tightens on a square cut shoulder. Another problem with running .037" or less of a shoulder is the brake will tend to go from timed to over timed when taking it on and off over time. The...

    Gunsmithing Muzzle Brake Thread Size

    You don't have to turn it down. Some people just like brakes to be as close to the barrel OD as possible. Taking .037" off each side won't do much to the recoil reduction.

    Gunsmithing Muzzle Brake Thread Size

    I would do 9/16x24. .037" for a shoulder is pretty thin and it would be less if you relief cut the threads on the brake if the threads don't have it. I'd do a .875" brake turned to .800 and tapered to .700" with 9/16x24 threads.

    Anyone used Utah Rifles in Pleasant Grove?

    You might do a bit more digging on Deadly Precision. There are numerous customers that have posted issues with him recently. There was even one that got the ATF involved as well as a attorney when he wouldn't respond to several attempts for contact. He had his new Nightforce scope and 2500.00 to...
