  1. RSI Shooting Lab validity?

    Ballistics - Internal and External
    I'm contemplating purchasing RSI's Shooting Lab but I have some questions about the results it will give me on the VZ-52. 1. Steel cases. I'm planning to establish a baseline using Milsurp ammo which is all steel cased and Berdan primed. (And all corrosive!) I plan to develop loads in...
  2. FF or FFF in .50 cal. pistol?

    I have a single shot muzzleloader pistol (5") in .50 cal. I haven't shot it in about 15 years and forget what I loaded it with. It seems to me I should use FFF in such a short barrel, but I'm worried the weight of the ball might create a lot more pressure. Also, any suggestions on the volume...
  3. Pull 'em or fire 'em?

    Handloading Procedures/Practices
    I bought some what I thought were 170 gr. .308 lead flat nose gc bullets from a private party over the internet. The bullets look flawless and I really wanted this load for my 30-30 for some hog work. But after loading some rounds, I tried to cycle them through the action. The bullets press...
  4. Powder Pressure/time/burn rate characterisitics

    Ballistics - Internal and External
    I am relatively new to the details of Hand Loading and have found little in explanations about the variation in burn rate of a given powder with the pressure at which it is burned. Intuitively, I think that the 'burn rate of a powder would be affected by many things such as it's chemical...
  5. Firearms Pressure Factors (CD-ROM Book)

    (I was surprised when I did a search and found nothing as I figured that someone else would have already 'reviewed' this book but it appears not so here goes. What follows is the review that I wrote-up for the Web Site.) --------------------------------------------- When you begin...
  6. 25-06 loading issue

    Handloading Procedures/Practices
    Hello to everyone I am new to this site and somewhat new to reloading. I have a 25-06 that seems to be showing signs of pressure in the flattened primers but I'm not totally certain. The specs of the load are below for you to take look at. If I could get some feedback that would be great...
  7. Pressure to cycle a blowback pistol

    Ballistics - Internal and External
    Hello folks, This is my first time posting here, so forgive me if this is not the correct spot to pose this question. I am very interested in the specifics about blowback gun physics. Not with bullets mind you, but the pressure they exert on guns and how that pressure is distributed to the...
