    I just got a bag of lead bullets from gwhaling (thanks!) and I was wondering if I needed gas checks, or if it would be okay without them. Here is the set up I was planning on;

    140 gr lead bullets
    6.0 gr accurate #2 powder
    CCI 500 primers

    For 5.9 gr (the starting load) the velocity is 1,016, and the max load of 6.6 gr gets 1,155.

    What say you?

    I need more information. You only need gas checks on high pressure loads. Typically magnums.


    Edit: pulled this from wikipedia, which explains it pretty close

    Okay, I measured each of the bullets and they all vary from 138.8 gr to 139.8 gr. I don't think that using the 140 gr data for just a 1.2 gr variance at the most shouldn't cause too much of an issue since I am only going .1 gr over the start load. I know I am asking a bunch of dumb questions, but I would rather be called an idiot and have all my fingers than guess and have to buy a new gun...

    I didn't cast them myself, I got them from gwhaling. I am not sure if he cast them, or got them some other way. I'm not planning on casting bullets myself for a while yet. I will be checking the dia tonight after Lost... If they fit right, I'll be loading them up tonight.

    Look at the bullets. If the base is a smaller shank(compared to the major diameter of the bullet) it can take a gascheck.

    According to my book, putting a gascheck on a plain base bullet is not safe. I hope to hear why, from RCBS soon. I will post their response.

    Thanks for the good info jim! I went ahead and loaded without the gas checks. The dia. was the same all the way down the bullet. I am probably going to the range tomorrow so I will let you guys know how it worked out! Thanks again!

    If some Company says something is unsafe I would advise and expect everyone to follow "their" advice/instructions. ,,,sam.

    Ive never been able to properly put a gas check on a Non-gas check bullet unless it had a tapered base smaller than the OD of the Gas check and would go into the ID of the check....anything else would deform or shave the bullet.

    Now,I hope this ends.Even tho I put gas checks on tens of thousands of flatbase bullets and shot them with nary a glitch,any one of them could have blown up in the past 25 or so yrs.I was wrong,wrong,wrong,wrong,wrong!All I can say about it is I WAS WRONG!!!(even tho it worked for me,I could have been blown into hamburger any minute in the last several years!) ,,,sam.

    I doubt I will ever have as much experience as you Sam. I mean, you've been loading since RCBS was just called R. :joke:

    I only put gas checks on bullets made for them. If the base of your bullet is a driving band I don't see a need for a gas check.

    there ain't a reason to put a g/c on a flat based boolit.
    you might not get much over 1600 fps but who cares in a revolver cartridge.
    the higher pressure runds might want one but i'd rather adjust the load.
    i'm guessing this is in a 357 here, but some designs are designed for accuracy not velocity.
    i'd still start at the low end and work up especially with a fast powder.
    lead does not respond like jacketed that plain don't care.
    your velocities sound like a 9mm not a 38 so i guessed at the 357.
    i'd recommend a slower powder like 2400 or slower for the vels you mentioned.
    just remember this when you see the leading.
