Your favorite FULL POWER 10mm loads for a 175gr. cast LEE TC bullet?

Discussion in '10mm Reloading Forum' started by 21Glock, Oct 28, 2012.

  1. Hi guys,
    I got a RCBS LAMII recently to lube and size my 175gr. .401 Truncated Cone bullets from a LEE 6 cavity mold. I'll be using White Label 2500 lube and BAC lube which have good reports on keeping leading to none or very little in the higher fps areas.
    For powder, I have on hand, Longshot and 800X and Blue Dot powder and want to put together some good FULL POWER loads for my Gen 4 G20 which has a 22lb. ISMI recoil spring and a SS guide rod to handle the hotter loads. New Starline 10mm brass and KKM 6" barrel as well. Wheel weights are my casting alloy.
    Any high end or nuke loads that you like and would recommend with this 175gr. cast bullet? I would like to use these loads for target shooting, SD and hunting.

    I cast and shoot them by the thousands. Very nice bullet. Great for target, OK for hunting if you cast them softer. WW lead is really too hard for hunting, especially if you water-cool them. At the higher velocities, the lube won't prevent leading. A GC or lube plating on the base is necessary near/above 1300 FPS. Not good for SD, unless you keep them soft and velocities unrealistically low (like .38 Spl low). Otherwise they just punch holes, rather uneventfully.

    U load mine for hunting cast with ww and about 20% pure. I coat the bullets in 3 coats of LA. Base included. Loaded over 11.2 gr of 800x. Very powerful over book load. Brass seems fin. I could probally work higher if I want. I don't have any leading. It's a wicked load. Destroys all. Swings steel plates like the 44.
  4. What kind of velocity on this load? I'm using white label 2500 in my RCBS LAMII, which is rated to keep a bore from leading all the way to 2500fps. I'll coat the base too on the hottest loads. Heard alot of good things about 800X, picked up some at the last gun show.

    I only use my 175 grain cast TC's for plinking/target over 10.4 grains of Blue Dot...
    Use tons in the 40S&W brass also...

    But these are not the best choice for SD or hunting unless you are very up close and personal and a humane kill is a head shot only.

    I beg to differ. The flat on the tc lee is quite large. It actually does pretty well as a hunting bullet. There are better choices but I would not hesitate using it if its all I had.

  7. What kind of fps is the 10.4 gr. of Blue Dot showing for your gun?

    Factory barrel, or longer after market barrel?

  9. Thanks, I have 6" KKM barrel, so a 11gr. load should be around 1200fps+

    I have shot a 165gr. JHP load with 11.0-11.50 gr. of Blue Dot and chronyed around 1300fps+ or-

    Im still working with this bullet and trying to find the load for it, but so far it looks like 9.5grs of longshot, WLP primer (i have since switched to CCI 300's)
    and an OAL of 1.25 is the winner!
