205 gr WFNGC LBT bullet loads

Discussion in '10mm Reloading Forum' started by doverpack12, Jun 1, 2013.


  1. Just picked some 205 grain WFN GC LBT bullets up at the gun show this morning from Going Ballistic Bullet Co. (link below) Any suggestions for loads I have Longshot, AA#9, and 800-X. I was thinking of starting with the longshot and working up from a minimum book load with a 200 grain bullet. Looking to end up at about 1200 fps maybe a little less and no more than 1225 fps. Whatever gives good accuracy in that range. I would prefer to do 800-X as a final option even though I will hand weigh all charges since these are very important loads for large angry animals.

    That bullet profile looks very similar to the Double Tap and Beartooth 200 gr. WFNGC hardcast bullets. Beartooth has a double groove like the one you show above. My experience below is not with your particular bullet, but the bullets I mention above. Stock G20 4.6" barrel.

    Of the powders that you mention, I did workups with 800-X and Accurate no. 9. Accurate no. 9 gave about 50 fps better velocity (1205 fps average), tighter groups and velocity spreads, and brass looked less "tired" than those from the 800-X loads at 1150. For 800-X, I was a good ways over book maxes, and with Accurate no. 9, I was still within at least one book load.

    Back when Speer still made a 200 gr. TMJ, they and Accurate posted load data for that bullet for Accurate no. 9. Accurate's max was 13.5, and Speer's was 14.0. Splitting the difference between the two gave solid results. I did not have any worrisome indications of excessive pressure, but did not see any reason to go higher. A 200 gr WFNGC hardcast bullet @ 1205 fps is a smacker.

    BT and DT have a bhn of 21, and I did not notice what the hardness of the Going Ballistics bullet is, so please workup carefully.

  4. I asked the bullet maker himself what the hardness was before I bought them and he said right at 20. Thanks for the recommendation.

    Another point:

    Leading can be an issue if the bullet does not properly fit the barrel. Another thing to carefully watch as you are doing load workups. Leading most likely = that bullet is not a good fit for your barrel.
     
  6. I loaded some up and after working up from 11.0 grains of AA#9 I settled on 13.0 grains going 1200 fps avgerage. I am now going to test for accuracy and if I don't see what I like back off by 0.2 grains at a time going no lower than 12.6 grains which gave an average 1165 fps.
     
  7. This design will take game cleanly and effectively Imuse in in many calibers rifles and handguns. 357 up to 475 Linebaugh I ordered 500 of these I guess after you order he calls for payment?
     
  8. I don't know about the ordering process. I bought them face to face
