    Ideal Twist AR15

    There was a magazine produced by an independent, then picked up by DPMS, that could shoot that load from the magazine; a modified bolt catch was also required. Externally they appeared to be standard 20-round magazines, but they only held 8 rounds in a single stack; the case heads ride in the...

    source 2"-2.5" tall scope rings

    I don't know of any rings that tall. There are many options at 1.5" - my preference is the Burris Signature line; the offset bushings let you center up and/or add a cant, they grip well, and they don't mark the scope tube. You can put the shorter rings on a riser rail to get the total height...

    Danger in AL sludge??

    Be aware of the fire hazard of such fine aluminum dust - do not let it dry, and do not create a dust cloud. Fine metal particles are much more flammable than bulk metal, and a flash burn releases a lot of energy in a short time. Be sure that you use coolant when making fines - the heat at the...

    GUNSMITH question

    Threading the barrel involves reducing the muzzle diameter. That has been shown to produce a slight increase of the bore diameter at the muzzle - essentially making a miniature blunderbuss. Lapping the bore after threading the muzzle can overcome this, but it takes some skill. If the rifle...

    just how hard to convert a die to bushing ?

    Most commercial dies are through-hardened, so you'll probably eat some tooling if you try. It's probably more cost-effective to buy a new bushing die.

    It looks like it's a carbon ceramic material; it's relatively inert and is often used for electrodes.

    Can any/all bolt actions break to fire when put in battery?

    Usually with modern actions and triggers, the worst that can happen is that the sear will not catch, so the bolt will decock as it's closed. I have seen triggers that will allow the rifle to fire when the safety is on and the trigger is released, but that was a special case (used as a demo in a...

    Moly in barrels

    Tubb Experiment - Moly in Powder David Tubb did an experiment in which he added moly to the powder rather than plating the bullets. He did that to test the hypothesis that the primary benefit of moly is by reducing flame temperature. Adding moly to the powder worked, but the results were...

    what chrono you guys using

    +1 for CED - best hobby chronograph on the market. I usually shoot late in the day, so I got the IR light kit. I blocked the diffusers with cardboard so the only light is from the IR kit - absolutely consistent lighting.

    weight sorting brass.....

    I did an experiment several years ago to determine just how much effect brass weight has on .223 loads. I used WW brass (sized, trimmed and deburred, primer pockets uniformed, flash holes deburred, and neck turned) , WSR primers, charges of RL-15 or N-550 powder weighed to 0.1 gr, and 75 gr...

    How much to bed?

    The 40X is stiffer than a 700, but the rear action screw is still located in the tang so it isn't as stiff as many custom actions. It would still be a good idea to bed 2" of the barrel to minimize the load on the tang from a long and heavy barrel. That's my 2 cents, and some will probably...

    Sorting Bullets For Long Range

    I can believe it. I shoot a spacegun in .223 for Highpower and Long Range, and initially tried sorting 75 gr A-Max and BTHP bullets, but they were extremely consistent - even between lots. Weight varied no more than 0.1 gr. OAL and bearing length varied 0.001". Concentricity (bullet in lathe...

    leade angle

    I've been using a custom .223 chamber with a 4 deg per side leade for the last year. Accuracy was the same as a 1.5 deg leade, as was the throat erosion rate. My loads worked as always, with no change in velocity and no signs of elevated pressure. The sole advantage I've found is that the...

    Neck Turning Tool

    If you want to stay with the turner you have, Sinclair Intl. sells a case driver (~$25 for holder and driver) that's worked really well for me. For doing.223 brass in volume for Highpower, I use a Gracey Neck Shaver. I do everything else with a Sinclair turner and driver.
