      I know gain twist is harder to make and little more expensive but if you want more velocity and less pressure and more precision and less recoil then use gain twist

    I watched a video on gun myths about 30 years ago that some guy with a gun shop produced and brush busting bullets was one of the myths. He made a stand that held some small twigs, roughly pencil diameter-ish horizontally and he shot through it with a variety of rifles. He had a target 3 feet in front and 3 feet behind the brush and the rifle was placed in a rest so the bullet would pass through both targets. After aiming the rifle and placing the brush he fired. Even the 50 BMG keyholed completely sideways in only three feet... I don't shoot through branches at game.

  • @waynemensen4252

    The one mistake I made was to load a solid copper bullet with the same charge as the same weight lead core bullet. I did so when they were fairly new, and I didn't search hard enough for data. The solid copper takes a lower charge to get the same pressure. I had to send my gun in to have the bolt repaired as it was over pressured and would no longer extract the empties after three shots.

    Read Ammunition Demystified on Jayden Quinlan's recommendation. Covers internal and external ballistics very well. The sequence of events before, during and after combustion are detailed. The many aspects of dispersion are explained. The what and how of dynamic and gyroscopic stability are covered. Components are covered. Practical statics and measuring variability are covered. Why error budgets are useful. Included are war stories from actual experience.

  • @georgelza

    Very interesting chat... love these.
    @53:00, Jeff talk about barrel ID expanding... but then mentions why is that expansion less at the muscle end vs the chamber...
    just a thought... at chamber pressure = higher, space = lowest leading to expansion = highest, as the bullet moves down the barrel, aka the area between case and bullet expands/are of impact grows larger, but with larger space and same volume of gas = reduce pressure = reduced barrel ID/OD expansion.
    can be totally off the target here.

  • @derekedgley5074
    @derekedgley5074 Год назад +1

    The most interesting and informative podcast so far from a hands on standpoint but it predicates a question for the trio to answer please for me:
    I determine a load for my 6.5PRC using a certain powder and Berger 130VLD Fed 210 primer N165 59.2grains and I eventually obtain a three shot group giving 0.30
    I then load another ten
    I clean the barrel thoroughly and religiously after every 10shots.
    Using this data obtained I then proceed to shoot a fouler after letting the rifle and ammo to adjust to sit outside to adjust to the particular ambient temperature invariably 3-7C at this time of year most mornings.
    I then fire off the fouler to warm and foul the barrel then proceed to shoot my next three /three shot groups resulting in a 0 40/0.50/0.30
    SD across the nine shots is 8 and the ES was 12
    This predicates the question
    Are these results a fluke?
    Can I assume that combination on that particular day weather conditions prevailing is capable of a consistent at least 0.5" group of three?
    The next day little or no wind again I shoot a 0.4 then 0.3 and think I'm good to go and load out 40
    I then shoot several deer out to 325yds ok deer size target
    What's your take on this please. It took 21 rounds excluding foulers for which I use some very little used old design to get to where I got the 0.30" first group changing powder weight slightly and seating depth backed off from jam

    A big question occurred to me when Mr. Siewert said he is having a 30-06 built: Is he using the SAAMI chamber or a "match" chamber? Almost all recent cartridges use a tight-freebore followed by a 1.5° half-angle throat-style chamber. Some people who use custom barrels, even for older cartridges like the 30-06 or even the 280 AI which have a SAAMI chamber without a freebore section.

    The marketing department bullet design reminds me the story of the Savage .250-3000 cartridge. Charles Newton wanted to develop ammunition with longer, heavier, 100 gr or heavier bullets for the Model 99 leveraction. The marketing department wanted to advertise a 3000 fps cartridge regardless of the utility of the lighter bullets.

    I'm wondering why do 22LR have 1x16 twist? Is it related to velocity? VS a 22 center fire that have 1x9 10 11 or 12 twist

    • @slickrick809
      @slickrick809 Год назад

      Most commonly used 22 centerfire bullets are heavier than most commonly used 22lr bullets. That's a big reason for difference in twist rates. Velocity? Not sure about that.

    👨‍🔬 I have some Powder Questions: 1.) Doesn't increased surface area, by the shape of the powder, increase the consistency of complete combustion? 2.) Aren't Ball Powders, because they have less surface area, not as reliable in providing as high of velocities because of incomplete combustion? 3.) If you were to used the principles of Geology, by using multiple sized balls for filling the pore spaces within the case (A Powder Compaction Method), you could fit more ball powder into the case - as to increase bullet velocities! 4.) Then, if you found the right "combustion combination" - between the little balls and big balls of powder - you could increase bullet velocities and accuracy! But, still do so, without overpressurizing the case! 5.) Isn't their a way to increase the surface area of Ball Powder "Like Shapes" (like pollution control equipment ceramic balls or those used in a catalytic cracker of a refinery) and using this "multi-size powder compaction method" - to increase both bullet velocity and accuracy - through better combustion methods? 6.) Or, improve powder combustion with the use of origami, for improved powder shapes and better combustion within the cartridge case? Your Thoughts? 🕵️‍♂️

  • @ronlowney4700
    @ronlowney4700 Год назад

    🧐 I Have A Bullet Question: First, regarding the "Accuracy" of Lead Core Bullets vs. Monolithic Solid Copper Bullets! Jeff mentioned the expansion that takes place from within a lead core bullet (lead, of course, is more malleable, because it is softer) as it driven down the barrel! Does that changing of the shape of the bullet, in the way it expands, stabalize the bullet by changing the center of mass? Or, is it because lead is still denser than copper and it helps to stabilize the bullet better - due to the center of gravity of the bullet (because lead is denser than copper) ensuring that the center of mass of a shorter bullet prohibits as much wobble of the front of the bullet from happening? 🤔 Your thoughts? 🤷‍♂️

    • @ronlowney4700
      @ronlowney4700 Год назад

      👨‍🏫 From a "physics standpoint", it only stands to reason that the farther away that the nose is from the center of mass of the bullet - once it starts to wobble - the harder it is to stabalize it! It is like the use if a Fulcrum - a "mechanical advantage" is gained by a longer one - so, it is easier to displace the load as the length of the fulcrum increases! Also, if the bullet expands - after hitting the lands - in a vertical direction and changing the shape of the bullet in the x-axis direction, then the harder it is to create a wobble on the tip of the bullet, as the bullet leaves the muzzle! Think of snow shoes - the wider the shoe, the easier it is to displace the weight (downward force sideways, in the opposite direction), by increasing the surface area! 🤔

    Very informative podcast! As a shooting nerd, I find the ballistic topics very interesting.
    Regarding ideas for future podcast topics, perhaps some discussion of the development of some of the heavy hitters would be interesting. Specifically, the 375 & 416 Rugers, and the breathing of new life into some of nitro express cartridges, and the influence of Craig Boddington on the same. Maybe get ole Craig on the show!
    I realize these cartridges are more specialized and lack the broad appeal, but personally I think listeners would find a big bore discussion interesting.

  • @northernoutdooradventures3883
    @northernoutdooradventures3883 Год назад

    Does increasing twist rate increase recoil? This is a thought experiment I've been toying with, but can't full explain. I figured this would be a good place to find some people to sound board.
    I think am thinking there is more recoil because the bullet would gain rotational energy. That increase in energy would ultimately result in more recoil. What i can't explain is how the physics would convert recoil into rotation??

    Duplex loads are not new. Elmer Keith was doing that before WW2. Gain twist has been around for a century. I agree with "inherent accuracy of a cartridge" as being fairy dust mythology. A bullet does not care or know what cartridge pushed it out the barrel. To say that a particular Cartridge generates a more accurate special kind of 60,000 PSI is basically a nonsensical Believe.
