    Fireforming .303 with O rings

    Interesting. I shoot cast bullets from my collectible 303's so I simply seated the bullets snug to the lands on the first firing with new brass and carried on with neck sizing. Never thought of o-rings. You learn something new every day!~Andrew

    A question of scale?

    Since the measurement of a group size is in a straight line between the centers of furthest bullet holes, the "half inch" group is "twice as good". If you want to reinvent the process and measure area, then yes: 4 X as good.~Andrew

    Bullet Jump

    If you seat to manufacturers spec length it's not taking up any more powder space than it should. Only in very special circumstances to I even care what the distance to the lands is, having loaded all my ammo to the spec by the manufacturer. I have a four 300 AAC Blackouts -two bolts and two autoloaders. In all of them,110 grain Nosler/Noviesky ballistic tips will shoot well under MOA in a chamber throated for 240 grain bullets. Don't know what the 'jump' is but it must be considerable. Just one example.~Andrew

    Electronic Seating Force Monitor

    Nice piece of work. Years ago I engineered something similar for compressing the charge in black powder loads where uniform compression is critical to accuracy. It worked well enough. Later I saw that someone was marketing a gauge that slipped over the ramrod of a muzzle loading rifle to measure charge compression in that venue. Not the same application but similar technology.~Andrew
  6. What do you call 'longer' ranges? We hit half-pint-sized prairiedogs at 400 yards with standard varmint bullets. I've shot 70 grain RDF at steel targets at 850 yards using a stout charge of Varget.~Andrew

    Small base resizing dies

    I use them in 223 and 308. I have several rifles and handguns in those chamberings so this allows interchangeability between them. Brass fired in a SAW almost always needs it. I have several AR's and A Browning BAR in 30-06. Needed to buy a SB FL die for that one too.~Andrew

    Remington 700

    If this is sudden onset, I say the Extractor. I have replaced dozens of them -particularly back in the 80's when 500M silhouette shooting was very popular and the 700 was (often) the gun of choice.~Andrew

    How to bone a deer...

    I bought my butchering /boning knives from this guy and follow a lot of his methods -tho not at that speed. What makes this look easy is the fact that he is doing it on relatively warm meat. Yanking muscle groups off of bone at 38F degrees is not that easy. He is good though...~Andrew

    .44 mag advice

    I agree to all of the above with a small exception: When you seat and crimp in the same action, the bullet is still moving as your crimp is being applied. Old time pistol shooters considered that a source of inconsistency. It was beaten into me at a young age to do it in two steps, always.~Andrew

    You're joking, right?🤔~Andrew

    .44 mag advice

    I've got a different method. Best diameter of a cast bullet has little to do with the groove diameter (tho a couple of thou usually handles it). When I shot Cast Bullet Assn Bench Rest I sized bullet to .001" under throat diameter. Without having Cerrosafe to cast the chamber, you can do a pretty credible job by balling up thin aluminum cooking foil tapping it into the down range end of the chamber while having a .44 jag on a rod positioned to use as an anvil so the wad can expand to fill the void. Sounds crazy but it works pretty well. Tap it out and measure the foil plug you've formed in the shape of the chamber/throat and go .001" less than the throat. As was said, the devil is in the details....and there are a lot of them.~Andrew

    .44 mag advice

    I have been shooting 44 magnum for 40+ years and almost all of it with handloads and cast lead bullets. All of the above advice is good, but with lead alloy bullets it's important to remember that with a well-fit bullet, velocity does not cause leading; pressure that exceeds the yield strength of the alloy does. Velocity and pressure do not go hand in hand. A look at a Lyman manual will show that some of the fast burning shotgun powders give low velocities but with pressures in the jacketed range. As was pointed out, it's a matter of time. How quickly maximum pressure for the cartridge is reached. A charge of very quick powder burns quickly and produces little gas to push the bullet. Slower powder just the opposite resulting in a slower peak and more gas volume to push the bullet. (simplistically speaking) If you have a bullet that is hard cast with a gas check, you can drive them at jacketed speeds provided you use the correct powder -one that gives the velocities you want but staying within the pressure constraints of the particular alloy of the bullet. I shoot .225" , 56 grain cast bullets at 2750 fps with MOA accuracy and no leading using this principle. With that said, Bullseye is a terrible choice for 44 magnum. I used it waaay back for 38 Special revolver loads but finally switched to Unique. The Bullseye was too peaky and a double charge would be disastrous. (I wasn't worried about myself but the thought of my beautiful Colt Shooting Master revolver disintegrating is heartbreaking) I still have the original canister of Bullseye I was using, unloved and unused. I have zero experience with Vhit powders so I cannot advise. I used Accurate 5744 and Alliant 2400 for my 200 M handgun loads, and hunting loads from my Remington 44 mag bolt gun and assorted handguns. They worked well. Unique was also a good powder but with bullets in the 240 -255 grain range, about 10 grains was all you wanted to use though I recall 12.5 was the top?? In any event, I settled on 8-10 grains. Since You are using a rifle, I will warn that to use cast bullets to the best advantage, your bore should be as free of copper fouling as possible. Copper will cause leading and inaccuracy. Really get the bore to bare metal for cast bullets. I shoot a lot of cast bullets in CF rifles from 222 to 30-06 and all are dedicated cast bullet guns. No copper jacketed rounds go through them. Good luck.~Andrew

    Why not load to the Hornady specified length of 2.24" ? It's what I use.~Andrew

    Concentricity gauges

    I have often said that I would give my concentricity gauge to anyone who knocked on my door and asked for it. I have the Hornady and it worthless. Even using cheap Lee dies I'm within their standard of .003" run out and indeed, straightening out ammunition didn't produce any results I could see on paper or steel. I bought the Hornady on a lark (gift cards) and it was the straightening device that got my interest. With out it, the tool is just showing you something that, by in large, you can't do anything to change. You can buy different dies or do something differently, but that is a deep rabbit hole to fall into. FWIW, my FL resized cases with bullets seated to full depth gave the best run-out readings for standard commercial dies.~Andrew
