    That's okay with me. They're going to do all the weights in one buy so it doesn't matter if I'm the only one that wants the 400 grain one.

    Ross alley cleaner

    John asked me to post this latest design for his 400 gr. "ROSS ALLEY CLEANER".

    According to my program it will cast at 396 grs. in wheelweights.

    The first attachment "John Ross 396 gr. rev1.pdf" is a 3D pdf file that opens with Acrobat reader. It seems to be working on the forum so I thought I would try it. It will open up full screen (or at least did in the preview), scroll down until you see the image and left click on it. That will open the 3D pdf which you can pan, rotate and zoom using mouse buttons.

    I am not sure how well it will work so included a 2D pdf file as well.

    Cool 3D pic!

    On p. 187 of Keith's SIXGUNS he has a pic of three Water Patrol officers (mis-identified as Border Patrol) shooting Winchester Model 97 trench guns, which Keith calls "the best alley cleaner of all."

    The .500 S&W can, with the right bullet, duplicate the ballistics of a 12 gauge with slugs. I believe that with this bullet, cast of the proper alloy and with the cavity filled with paraffin or somesuch to promote violent expansion, we can approach the close range performance of a 12 gauge with buckshot.

    I'll find out.

    Hi Kent and John. I like the looks for alley cleaner, I have some modeling putty that will fill that cavity and stay semi pliable. I will have to try it on some of the 700gr HPs. As big as the cavity is on that one I could mix in 6-8 BBs and have a real shotgun effect.

    Here is the 400 grain drawing, John.



    So, are you happy with the bullets now? Shall I go ahead and start the group buy?

    I think 69daytona is talking to Mihec but not sure. I also would like to know how much the solid version would weigh with this design. Also, I hate to repeat the same discussion (please go back to the post #32~#39) but would like to have bore ride diameter to be slightly bigger (.495") and meplat to be slightly bigger(.475" or 95%).

    It is John's design so I will leave decisions up to him but I can make whatever changes people want.

    This was a first cut based on the info I had.

    Not being a .500 S&W shooter, I do not know the exact dimensions needed so please correct me if I am wrong somewhere. Bore ride diameter can be increased if required.

    The solid version will weigh about 473 grs.

    The hollow point will weigh about 396 grs.

    I have also drawn up a gas check version for 69Daytona. This is a first cut as well with the only real change being the gas check shank.

    It will weigh 391 grs. solid and 469 grs. in solid ~ both without the gas check.

    All weights based on wheelweights and calculated by the program. Obviously, minor changes in nose radius, length, meplat diameter or hollow point size will affect weight so can be adjusted to hit a specific weight it that is the goal or specific dimensions can be set and that determines final weight.

    Hi folks, The LDPE material John is talking about is available from Buffalo Arms in Ponderay Idaho. It's available in .030 and .060 thickness. Good people to deal with.

    Thanks for that Don. I searched the site for LDPE and came up with zilch. Do you have the specific address for the stuff?

    Spartacus, go to their web page and scroll down near the bottom of the index and click on wad material. They carry vegetable fiber, puff-lon and poly, poly is what you want. They have press mounted wad punch dies for different calibers but the one for .50 cal. is listed for rifles and may be too large (.512 ? ) I have one of the wad punches to cut vegetable fiber wads to shoot in my Sharps rifles for black powder loads. Hope this helps, let me know and we'll try again. Keep your powder dry, Don

    Got it Don and thanks again. Here is the link:

    http://www.buffaloarms.com/Products.aspx?CAT=4108

    Now I am wondering... instead of cutting this in rounds with a punch, could I cut it into strips and insert it between bullet and case in my re-loader so that the brass case would naturally cut the correct size and push it in with the bullet?
