    I have 2 of the "Monkey Wards" models plus a very nice M91 rifle and a M1909 rifle. They are excellent shooters. The middle rifle in photo is a M91 I converted to 35 Rem. The wire wrapped around the top M91 is attached to a strain gauge on the...

    Given the NOE 314299 or the Lyman 314299 cast of a good alloy with GCs and a good lube getting 2100 fps out of a longer barreled MN without leading will be easy. Getting 2100 fps with the best accuracy will be hard. It can be done though with...

    Depending on powder and cast bullet used 320 fps, while seemingly a large amount, could simply be the difference between the 20" and 26" barrels. Also the load 's time/pressure curve will have a greater influence in the longer barrel. There is/was...

    The larger the diameter of the bullet the more mass it has from the center of it's axis of rotation. Thus it has greater rotational velocity at a given rate of spin (RPM) than does a smaller diameter bullet at the same rate of spin (RPM). Only a...

    That's okay. I was just trying to clarify. I am coming to think more and more that twist rate especially with cast is very important and that too fast might not be a problem with jackets but it is with cast. The rpm threshold is real the Swede...

    This may sound funny until you think about it. To check your method measure a one shot group. The result needs to be .000" If you method gives you something other than .000" you are introducing inaccuracies in what you are doing. On a 38...

    I load 99% of my ammo on 650's or 1050's. Using the 650's or 1050's I can get the runout to equal to the best single stations. Start by isolating were your runout issue is coming from. Check your cases before you size than after sizing than...

    Yes the 16" twist in a .30 caliber does work extremely well stabilizing bullets under 1". That is what my 30x60 XCB rifle has; a 31" long Palma contour Broughton 3 groove barrel with a 16" twist. However, you the OP stated you have a 10 and 14"...

    M-Tecs replied to a thread Primer Detonation in Our Town
    Yes and no. WD-40 and penetrating oils when put directly into the primer will inert it for a while. When I tried it the inert phase lasted a couple of days to a week or more but everything fired after a couple of weeks.

    Primers are hard to kill. I tested some of the various oil methods. Given time even the oils won't keep them inert for long. I was give about 6K of primers that had been under water for several days. After drying I used them for shooting...

    Various methods are used and greatly argued over. Level of precision mostly determines best method. On larger groups the inside edge to the outside edge of the two widest shots is the simplest. Outside to outside subtracting the bullet diameter...

    Yes, the Lyman M-die/expander that came with the die set will work with .358 bullets. It will flare the case mouth (just as the Lee does) and expand the inside for .355 - .356 bullets. Thus you're putting a bullet in that is .002 over what is...
