Thread: A new Lil Gun favorite.

  1. #1

    A new Lil Gun favorite.

    Much has been written and said about Hodgdon's Lil Gun in the .22 Hornet. If there is a better powder for that cartridge, I haven't seen it yet. Lately though, I have been experimenting with Lil Gun in straight walled pistol cases; specifically the 357 Magnum and have pronounced it, with few reservations, a very good powder for that cartridge, indeed.

    This evening I revisited my Model 27 S&W, eight and three-eights incher using Hornady 158 grain XTP bullets and the starting charge of Lil Gun which is 16.0 grains for a listed 1504 fps. (Hodgdon's data is from a 10" barrel which I'm certain is a pressure gun barrel, not a revolver.) Accuracy was as good as I could hold. My 25M groups ranged from 1.3" to 2.4" standing. My 50M groups ranged from 3.2 to 4", again, standing... and this includes the ones that 'got away' from me because i can never get used to how exquisite the trigger is on this revolver. Accuracy is excellent, but that is secondary to the ballistic qualities.

    Hodgdon lists the pressure as 24.1K CUP for the load I used. Maximum charge is 18.0 grains with a pressure of 25.8K CUP. A quick look at the two powders bracketing Lil Gun in the lists show max pressures at 43K and 42K CUP respectively. That is a huge difference! Velocities are so close between the three that there is no practical difference between them on that count. The down side of this load is it being somewhat smokey at this pressure level. I'm hoping that increasing the load will stop some of that. As it stands, I can verify that it is a snappy load and judging from the trajectory. I'm getting around 1400+ fps from this revolver. When the weather dries up I'll chronograph it.

    I had great accuracy, easy extraction, and I'm certain my cases are going to last a while. Some of you lever gun shooters might want to take note. Judging from the fireball I was getting around sunset, this powder would appreciate a 20" barrel! ~Muir

    As an aside what is considered the shelf life of modern powders such as Lil-Gun if stored at a consistent room temp?

    If they stopped making this powder life with a Hornet would not be the same.

    Would make little difference to me, I have used both this and H110 for the 35 grain v-max and get far better results as for as velocity goes
    and group size is also better with H110.
    That does change when the bullets go up to 45 grains, but it is still pretty good with H110, but velocity drops off a bit compared to Lil'Gun.
    I have wondered from time to time if Lil'Gun would work in 7.62x39, but not having found any data, and not being abloe to run quick load
    that is as far as I have got with that.

    ....and way higher pressures.
    As to shelf life: I have some 1970 vintage IMR 4064 that I'm still shooting.~Muir

    Could be. I've got some Korean-war surplus powder I'm still using as well.~Muir

    Very likely, but with well over 20 reloads of 11.5 grains (of H110) and so far never needed full length sizing I have to ask if it really matters ?

    You are getting very much more pressure. (about 30%) Does it matter? Probably not, and I like H110 as well. (H110, Accurate 1680, and Lil Gun= top Hornet powders) I just load to pressure these days. I will sacrifice a few fps for a significant reduction in pressure.~Muir
