    Recommended free ballistic software?

    I have no problem reading the font size. If you choose a ballistic calculator that prints in a large font, you become restricted in the total range, and the increments in range, that can be displayed on ONE sheet of letter-size paper. Jim G

    Recommended free ballistic software?

    I use the Hornady ballistics software available on the Hornady website. I used to use the ballsitic sftware on a different website, but one day when going there I encountered a warning that the webssite was not safe. Evidently, it had been hacked. So, one of my reasons for staying with the...

    That puzzling "securing screw" on the Forster press

    Yes! I am guilty of this myself. The Forster works SO well that it gets cleaned only rarely because it never seems to screw up. It is refreshingly reliable and adjustment-free compared to my progressive presses. Jim G

    That puzzling "securing screw" on the Forster press

    Jmorris and others: THANK-YOU! I am SO glad I posted. I had never received the obviosuly much longer "user manual" that Jmorris linked to, with my press. I got a mUCH shorter version that did not even describe the proper disassembly and reasembly of the multi-layer "jaws system" that securess...

    That puzzling "securing screw" on the Forster press

    I've had my forster press for a few years now and had never noticed a screw, which I'll refer to here as a "securing screw", that is located on my Forster press, within the head, to the operator's left. You can see the screw just to the left of my micrometer seating die in this photo: That...

    Most ft./lb energy per grain of powder?

    That IS impressive! And, particularly so when you do the math and see that the projectile has 149 ft lb of energy, and realize that many of the factory 9mm loads only have a bit over double of that! Now practical usage outside of your supressed squirrel hunting scenario is admittedly narrow. I...

    Most ft./lb energy per grain of powder?

    I think that the onyl reason the powder efficiency of the 45-70 is not better than that of the 308 is the low percentage fill of the huge 45-70 case, which was designed to accept black powder versus smokeless. That makes that particular comparison invalid right from the get go. I WOULD suggest...

    Most ft./lb energy per grain of powder?

    And, the worse the barrel life gets also. Jim G

    Most ft./lb energy per grain of powder?

    You might ask yourself, WHY even ask this question, since it contains an obvious implied contradiction: The energy content of a bullet in effect measures the potential killing power of the bullet, assuming of course that the combination of weight, caliber, and bullet shape is appropriate for...

    Powder for 45-70 used for CAS side matches only

    The 5744 has proven to be a GREAT choice. The standard deviations are single digit, with both cast and jacketed bullets, and primers look great, Jim G

    Early testing: Might replace my hand cast powder coated 500g bullets for my Pedersoli with 350g plated swaged Spitzer

    Yes! That's why Hornady makes bullets with a Spitzer nose but the nose has a synthetic tip. That apparently provides the superior aerodynamics of a Spitzer shape but enables their use in the tubular magazines of lever action rifles. The synthetic nose is apparently good for hunting as well, as...

    Early testing: Might replace my hand cast powder coated 500g bullets for my Pedersoli with 350g plated swaged Spitzer

    The low BCs for those 3 bullets you mentioned would make them hard to use at ranges of several hundred feet. A key attribute of the Campro Spitzer bullet I am trying is its superior BC compared to most bullets of comparable weight and size. Jim G

    Early testing: Might replace my hand cast powder coated 500g bullets for my Pedersoli with 350g plated swaged Spitzer

    I read the same advice, but found that none of the 3 heavier bullets I tried (ranging from 474 to 500g), would group well from my rifle, AND had too much trajectory drop and too low a velocity to support shooting accurately at long ranges, AND apparently suffered transonic effects. Jim G

    Early testing: Might replace my hand cast powder coated 500g bullets for my Pedersoli with 350g plated swaged Spitzer

    I have been posting about my Pedersoli Sharps replica .45-70 rifle’s accuracy which has hit a wall, despite repeated improvement efforts with 500g class bullets when fired at my 150 meters = 164 yards testing distance. The 150 meter testing range is NOT my ultimate planned target range. I want...

    Why powder coating my .45-70 cast bullets might not ever make precise long distance ammunition

    I have examined the BHN of the bullets both before and after powder coat baking. Evidently these large heavy 500g .458 caliber bullets don't get INTERNALLY very hot during the 20 minute powder baking cycle, because the BHN does not change. I tried using commercially made Hi-Tek bullets in .357...

    Why powder coating my .45-70 cast bullets might not ever make precise long distance ammunition

    Why powder coating my .45-70 cast bullets might not ever make precise long distance ammunition I have been struggling with limited success trying to develop a (smokeless) load for my Pedersoli .45-70 caliber Sharps replica rifle using powder coated bullets. The best 5-shot groups I have been...

    Telescope eye relief question

    On the parallax thing: I was told that to eliminate, or at least greatly minimize parallax, I should hold my head at the distance from the scope that leaves a very thin black circumference around the scope image. This is achieved by starting "too far rearward" (i.e. longer eye relief than the...

    Telescope eye relief question

    At my last range session with my Pedersoli 45-70 buffalo rifle with its Leatherwood Hi-Lux Malcolm type full barell length scope, I realized that I was needing to hunch forward some distance, beyond what I would call the "natural" head position, to see the image in the scope with minimized black...

    Powder coated bullets: What max velocity can be run and what BHN required to do it?

    Hmm. My Pedersoli's thick (1" octagonal) and heavy barrel never gets beyond " a bit warm", never hot. Jim G

    Powder coated bullets: What max velocity can be run and what BHN required to do it?

    OK, that makes sense. On the BHN: Uing the alloy calculator, I carefully alloyed a mix of Pure Lead, Tin, and Rotomold's "Superhard (30% Antimony and 70% Lead) to make what was supposed to produced BHN 21.5. BUT, after a few days of aging, it was still only about BHN 16, and after over 2 weeks...
