    hybrid cases

    Steel heads. Are they still made? Been around for a while. You can go to some truly high pressures, but watch out for barrel damage. The leade will start to burn quickly.

    Custom...... Full length dies

    The case head to shell holder 'play' allows for better self centering of the case as it is fed into the die.

    The ejector tends to make sure the cartridge is canted by whatever clearance is available.

    A couple of questions after cleaning Benchrest guns

    It is pretty common for a thoroughly cleaned barrel to not behave as desired. Dirty it up a little bit. It is what 'fouling shots' are designed to do.

    Newbie questions

    Sometimes you need to be faster. Like a brief pause on an otherwise windy day. RBLP makes things go nice and smooth.

    Bullet diameter - How big is too big? 30 BR

    Do not forget that the bullet obturates. A fancy way of describing slugging up under rapid acceleration.

    fireforming barrel?

    My .22-250AI and 6mm-REM-AI have enough accuracy to go after groundhogs out to around 200 yards while fire forming. Kelbly built the gun using a PANDA ACTION and made the barrels. The only thing I did was mount a scope (8-20 with a doubler (around 18x to 40x) back when Premier Reticles...

    Federal Primers are changing formula?

    A little to much creative writing and not enough technical writing. They are pretty widely separated.

    Longthorne Gunmakers

    One of the details often omitted is the correct fitting of the gun to the shooter. It can involve bending stocks to put your head (and eyes) in the correct position. You need to be able to mount the gun to your shoulder and immediately see along the length of the barrel with one eye for...

    Bullet Production and Quality Control

    There is a reason they producer is a "boutique specialist." Stick with one of the larger BR grade makers. They are no inexpensive, but very, very consistent. Sound like equipment being run to fast. It takes a non-zero time for the lead core to flow to the die shape when swaging.

    It is not difficult to adjust for modern shapes.

    Tuner thread

    You never realize how useful a lathe is until you have had one and traded it off. here are so many 'little' things thatare just a few minute of lathe work but are a real hassle to do without one.

    Will my 50BMG blow up?

    The 'trick' to outrageously high chamber pressures is to have a 'built up' barrel and chamber area. The outer layers are heater, the inner chilled, and then they are pressed together. Think large gun artillery barrels. You can often see the steps where the outer compressive layer ends. If you...

    bullet stability question

    The Greenhill Formula is a decent approximation. A 6 degree of freedom motion analysis is as sure as it gets, but very difficult to set up reliably.

    Neck Sizing a Heavy Straight-wall Case to a Bottleneck

    I would give RCBS a call. You might even need to send them a drawing of the chamber. They used to be very good at this. They have a wide stock of dies that allows them to select multiple steps to get the neck down bit by bit (or 'die by die'). It may require inside reaming or outside turning...

    Torque with a claw foot?

    Anything that changes the length of the lever arm will alter the torque reading. Even a straight extension that is at an angle. If you make sure the extension is truly vertical, the affect goes to zero. It is not all that hard to correct for things like a crowfoot. The center of the square for...

    Ballistic Calculators

    A problem with measuring at the firing line is that it is a only a single point in the trajectory. I like shooting over grain crops. You can look at them and see the 'waves' in the wind across the field. The middle half of the trajectory is likely to have a greater effect. I use Pentax 10x...
