    Trimming Cases and the Carbon Ring

    Use Cerrosafe. Pouring hardening and adhesive epoxy into your action should scare you more than pouring a proven product made to release itself from your chamber. Cerrosafe also melts at a RIDICULOUSLY low temp, hot enough to cause contact burns to skin, but NOT hot enough to damage even the...

    Sizing Belted Magnums or (How I stopped worrying and embraced the false shoulder)

    In general, virgin brass is annealed before it leaves factory. So I pull up the diameter, then push back down part of the neck, which means I work hardened the hell out of that brass - so I anneal it after forming the false shoulder, size again, which does nearly nothing but is a good...

    Sizing Belted Magnums or (How I stopped worrying and embraced the false shoulder)

    The point of this thread is that you CAN prevent case stretch on the first firing, by pulling up a false shoulder. That’s literally the proposed premise of the thread…

    Sizing Belted Magnums or (How I stopped worrying and embraced the false shoulder)

    I wish folks would stop telling new reloaders to measure fired brass to set their sizing dies. So much headache would be averted. Your instance here, the fired cases were still short. In other instances - like the one I helped another loader with YESTERDAY - the loader will find out their fired...

    Grayboe Stocks, Opinions?

    Good to go. I had a Ridgeback for a short time just to test drive after a buddy test drove it. No complaints.

    Folks already have, ~15yrs ago.

    Offhand shooting practice

    As I mentioned above, in 35 years hunting in ~30 states and 3 continents, this is absolutely not true for almost all of the shots I have ever taken on game. I CAN shoot small offhand, but I prefer to take advantage of the dramatic improvement in performance offered by field expedient or field...

    This is amazing.

    Muzzle crowning.

    And your evidence to this assumption is…? Have you inspected the muzzle of this rifle?

    Muzzle crowning.

    If it isn’t, it won’t be.

    Barrel Treatments for 300 BO

    Don’t overthink it. Get the contour and gas length you want, from a maker with a reputation for delivering what you want from your barrel for your application.

    New AR15 upper with issues

    That tool mark cannot have happened when drilling the port. It's on the wrong side of the barrel. I wouldn't overthink the gas key staking, personally, I find that to often be much ado about nothing for 99.9% of AR owners. But that barrel damage isn't something I'd be happy with. In reality...

    Neglected Rifles-Rising Star?

    That rifle should have no trouble reliably printing 3/4MOA groups. We might need to eliminate a few hitches in her 'git-along to get there, and have to put together some good ammo for it, but if you can't relatively quickly find a 1/2-3/4moa load for it after a few tweaks, then I'd cut my losses...

    7mm Creedmoor——-who’s in???

    We had a pretty big vacuum in the 6 and 6.5mm realm which needed the right barrel twists and case volumes to justify. The same for 25cal - until we had >130grn bullets truly available on the market, quarter-bores didn't make a lot of sense as long range rifles. Now we have some. But the 7mm...

    The pitfalls of relying on reloaded ammo.

    So... you bought cheap reman ammo some years ago and are claiming the cause of the problem is that it was made by a reloader rather than a factory?

    Trimming Cases and the Carbon Ring

    Eh, to each their own. Some people screw their sizing die down to touch the shellholder, plus 1/2 turn deeper, and smile as they make undersized brass for their rifle. Some set their seating dies to seat bullets at whatever the book says for COAL, and they smile as they fire unknown jump to...

    Which bolt action .22 LR rifle would you recommend for accuracy from a bench or in the field?

    I'd have to check to be sure, but I'm FAIRLY certain that the only 2 Nikons I have left are a 4.5-14x Buckmaster and a 6-18x Buckmaster, both with side parallax focus. The 6-18x was a Midway exclusive with a mil-dot reticle, and with 1/8moa turrets. I used it for some time on an AR for coyotes...

    Trimming Cases and the Carbon Ring

    The more room we have, the more opportunity for eddy diffusion and more opportunity for deposition. A good example is a revolver barrel/cylinder gap - with a tight gap, there is too much resistance to flow out of the gap, so more pressure and more flow is retained in the bore. With a wider gap...

    Trimming Cases and the Carbon Ring

    Carbon ring deposits form between the end of the case neck and the end of the chamber neck. More room due to excessive case trimming (under-length case necks) means more room for more deposits. It doesn't really change location, it just gets longer or shorter.

    Trimming Cases and the Carbon Ring

    There are ways to make your own gauges, but Sinclair offers Chamber Neck Arbors which reloaders can use to detect the end of the neck in their chambers. It IS better to ignore SAAMI specs and trim your brass to match your actual chamber. Yes, trimming your brass to offer minimal clearance at...
