    308 LC Match brass questions

    The LC match brass, both cal. .30 and7.62mm, has uncrimped primer pockets. The easiest way to determine relative case volume is by simply taking examples of each type of brass you wish to load, weighing them empty, and then filling each with water to the case mouth and weighing them again...

    Rebarreling a Remington 700

    I guess I should have said 'good conditioned' take-off barrels - I myself have removed several brand-new Remington 700 barrels for custom barrel jobs, and a larger number of used ones, and the .270 (if that is what the OP wishes to have) is rarely found in badly worn or shot-out condition. I...

    Rebarreling a Remington 700

    Also, many gunsmiths have a number of original barrels which they have removed in customizing other rifles - some in new or near-new condition, and your barrel can probably be replaced with just such a take-off barrel. Ask your gunsmith. PRD1 - mhb - MIke

    How old is this black powder rifle?

    The photos are not very clear, but what can be seen is a modern reproduction, possibly Spanish, and not much more than, say, 50 years old, but likely newer than that. It does not appear to be an antique of any sort. PRD1 - mhb - MIke

    Springfield 1871 crack

    It may be that the 'crack' is only a flaw in the surface of the original receiver forging, and not a safety issue - such flaws are often visible on the receivers of 1873 Winchesters and some others of the same vintage.. I suggest removing the foreend and checking to see whether the 'crack'...

    Where to get a 9mm rifle barrel? Not for AR

    FWIW: 9mm rifles do exist - the Spanish Destroyer bolt action (q.v.), w/detachable magazine, in 9mm Largo. Most of them will also accept .38 ACP/Super ammunition, as well. PRD1 - mhb - MIke

    Favorite 7mm?

    The .276 Pedersen, for which I once owned a Vickers-Pedersen SLR, and for which I still have a custom sporting rifle in that caliber, as well as a full case (1680 rounds) of FA29 ball ammunition - though I don't shoot the old surplus, instead reforming 6.5x54MS brass. Not a well known or very...

    What is the nicest gun you were ever given as a gift?

    Quite recently, I received this as a completely unexpected gift from my friend and fellow member of the Historical Arms Society of Tucson (AZ), Roy Marcot. It was given to him by the builder, Jerry Swinney, and Roy just said that, of those he knows, I am the most likely to appreciate it. It...

    Group thoughts on Feasibility..

    The Stevens Favorite is not a good candidate for conversion to the .25-20 or any centerfire cartridge. The Favorite is a small action with takedown which renders it unsuited for the higher pressure centerfires - the single-shot Stevens action which is suitable for the conversion is the #44...

    Straight wall principles with bottlenecks

    Other factors being equal, larger powder charges to produce higher velocities WILL increase the rate of throat erosion. PRD1 - mhb - MIke - barrel maker, retired

    winchester tang sight

    I've seen both conditions of the staff out of vertical - leaning either fore or aft, or left or right. The shimming method works for the latter condition, but probably not for the former. The OP will have to clarify the nature of the problem, to permit correct advice on how to fix it. PRD1...

    winchester tang sight

    Are you asking about how to make the staff stand up straight, at a right angle with the bore? They sometimes lean forward or backward a bit, and may or may not permit correction. If that is the case, you may have to contact the manufacturer for instructions or replacement. PRD1 - mhb - MIke

    Winchester Slide Action Shotguns

    re. the BHP: technical Q...

    Like the 1911, the BHP's firing pin is an inertia type, shorter than its channel in the slide, and will not reach the primer until struck a blow by the hammer. It will not touch the primer when the hammer is lowered manually. PRD1 - mhb - MIke

    Headspacing on the belt ?

    In theory, they all headspace on the belt, and the gauges are designed to measure that dimension. In practice, the belt location varies so widely in the various cartridge cases that, after fireforming, the case should be resized just enough to permit headspacing on the shoulder, as is proper...

    S&W 52-2 semi-auto 38 Special ??? up for sale

    Knowing perfectly well that this is pretty far off the original topic, I can't resist the opportunity to post the image, below (and not for the first time, I'm sure) . Some previous owner obviously thought the serial number was significant and lucky enough to have it gold-plated. Since it is...

    is a longer bullet more accurate?

    There is no direct correlation between bullet length and potential accuracy. Short and relatively light bullets (for the caliber) have proven capable of outstanding performance in benchrest competition, where the highest level of accuracy is required. If you are thinking of the use of boattail...

    Obsolete calibers and cartridges.

    My take on obsolescence is that a cartridge is only truly obsolete when it is no longer available or reproducible from available components, or, finally, when nobody finds it interesting or useful. I have rifles and load for these 'obsolete' rounds, (among others) both of which are still useful...
