    9mm OAL

    I've been reloading 45ACP for about a year and just got in the equipment to reload 9mm and 40S&W. I use a Dillon RL 550B. I consider myself a novice and don't want to make any mistakes reloading these higher pressure rounds. I only have one hard copy manual, Lyman's 48th edition.

    I'm going to try the 9mm before the 40, using plated round nose, some of which are Berry's which seem to be more of a LCN or long conical nose. I use the data for LRN's or LCN's for powder charge. I'm also using Win 231 powder and Win WSP primers. I do have some Unique and Hodgdon Clays powder so please correct me if I'm using the wrong powder.

    While setting up my dies today there was no way I could come close to the manual's OAL of 1.125". It seems like the best OAL I could produece was around 1.067-1.069". The OAL of 1.125" comes from the Hodgdon/Winchester/IMR reloading data center web site.

    Am I seating the bullet too deep and thus causing too much pressure? Any help on reloading the 9 and 40 would be great.

    Sorry, I thought I had all the info covered. I'm loading 124 grain.
    None of my info gives the minimum OAL. I was pretty sure there is one but I just can't find it. BTW, I'm shooting a Glock 19.

    That is true glock recommends you not shoot lead however he's shooting plated bullets,the load criteria for plated is the same as lead,I will admit i shoot lead in my glock 17 and never had a hiccup ....yet but i clean it after about 50 rounds.The safest thing would be to buy an aftermarket barrel you can safely shoot lead out of.I haven't shot my glock in over 6 months due to other handguns I shoot that don't have the barrel situation

    I don't plan on shooting plain lead through my Glock, but I do appreciate the warning.

    It looks like my problem might be with either the plated bullets or the brass. I'm trying to reload some Winchester white box and Remington UMC brass that I bought and shot.

    My 124 grain berrys plated round nose will slide right in the brass without my putting any bell on the brass. The bullets are measuring at a consistent .354-.355. On some of the brass the bullet will almost fall in. Did the brass expand enough to not be able to use them?

    I have some brand new winchester brass that the bullets will not go in without some bell. I ran one of the new pieces of brass through the resizing die and a bullet will not go in it, so I don't think the die is over-sized.

    I never had this problem reloading 45ACP, but I'm still a novice and far from experienced so what am I missing?

    you need to buy .356 dia bullets so they fit the case tighter,the case will crimp tight enough to hold the smaller diameter round but after you fire a larger diameter bullet the smaller diameter will slide in the case mouth without belling
