    I was kinda surprised by the speeds my fav load put out.
    4.4gr WST,miss 200lswc,cci#30 @1.245oal
    Avg 847fps es 26 sd 8
    Ive shot my best groups on paper with it and it rocks my 100yd plate all day.

    By far it had the smallest es & sd of all I tested.

    Got data on a bunch of test reloads(I saved a small amount of every test load for when i got a chrony) and some factory ammo.

    Hornandy 45acp 200 ftx +p was the speed king:wow:
    Avg of 1032fps.

  3. Me too. I shoot a ton of WST in 45acp, tested just about every bullet style & wt with it. That is quite a bit faster than I get in several 5" guns. Double check your charge wts on a known scale. My working load is 4.8gr under a 200gr LSWC or LFP @ 1.250" for the LSWC & 1.220" for the LFP. My vel hovers around 830-840fps. So CCI #300??

    Yes CCI#300 LPP's

    I'm now a bit leery of my scale because of those speeds.
    I check zero before, always check every tenth load and make sure scale zero's out after.
    I'm going to have to get a check weight set for it.
    The scale seems very repeatable though:dunno:
    Lyman#49 shows those speeds for near max WST loads but DAMN is is accurate:wow:and still pretty soft shooting.
     
  5. I must agree with mr. Fred. I needed 4.8 to get 850 for a CDP load out of my MP45.

    I agree, too. I use 4.6 grains and do not get those numbers.
     
  7. WST is pretty stable across the load range, I never see it vary much. What scale? Zeroing a scale doesn't mean much if it is off or being used incorrectly. Check wts are the only way to know for sure. It could very well be right & you have a tight bore/chamber, but something is pretty far off getting those kind of numbers. My 45 minor load is 4.3gr under a 200gr for 730-740fps.:dunno:

    I think the scale is off as I got normal readings with factory ammo:dunno:
    Scale is a rcbs rc130,not a high $ unit.
    I ordered some check weights and when they show up I'll post results,I still have a bunch of that ammo left and will take a few apart to check.
    May have to get a better scale:whistling:
    There are some rcbs 505's locally.

    With out the chrome I would have never known:faint:

    Had I not stayed in the bunny fart load range I could of had problems.

    Is that from a carbine or something?

    Precision 200gr RNFP 1.205" OAL 4.55gr WST
    G21 749.7 FPS
    G30 716.5 FPS

    Precision 200gr RNFP 1.205" OAL 4.7gr WST
    G21 788.5 FPS
    G30 750.5 FPS

    Scale dilemma solved:wavey:

    Local guy helped me out.
    He traded a 5-0-2 RCBS for some of my CCI SRP's(I have plenty of those) and he checked the scale first with check weights and against his HIGH ZOOT digital.

    He also made me a temp check out of copper that weighs 4 grains which my old scale shows as 4.4gr :faint:
    Wrong numbers posted,old scale read 3.6 not 4.4-MORON alert.

    RC130 gets some pretty negative reviews on MidwayUSA's web site. If I understand you correctly, it was reading high (4.4gr for 4gr). I'm curious...if you drop 5 or 10 charges on it, does it read 22 or 44gr, or does it get closer to being accurate?

    I eventually discovered that my Lyman 1000XP digital scale was not accurate at single charge pistol loads. It's not as bad if I do 5 charges and divide by 5 to get the charge weight...but I always double check on my Dillon beam scale now.
     
  12. SO if that puts you @ 4.8gr, just about the vel expected.:wavey:

    That statement would mean that your scale was reading higher than actual weight, and would work in reverse to what others had expected based on your original post.

    In other words, you stated you were loading 4.4gr WST in your original post, so your scale was showing 4.4gr but the charge was actually 4.0gr. Yet, you were getting higher velocities than what others expected you should have at the stated charge. Something still seems amiss. Unless, you meant that your new check weight is actually 4.4gr and your old scale shows it as 4.0gr.

    Did your friend have actual check weights to check his scale, before making you a check weight?

    Too much confusion here. I would stop everything until acquiring a proper set of check weights. If 4.4 gr is the goal, zero the scale, set to 4.5. Verify with check weights and then adjust the scale to 4.4. The reason to start with 4.5 is that check weight sets often have the smallest size weight @ 0.5 grains. The RCBS standard set is a good example.

    Kudos for recognizing that there might be a problem, and checking it out.

    Yea my mind was multi tasking:whistling: and I buggered up the numbers.
    Old scale read .4 grains low.
    3.6 for old scale and 4 with the new.

    That a big error as the book range with that bullet and WST is 4.4 to 4.9


    10 throws of 4.4 measred at 44gr with old scale.

    Lesson learned,buy check weights with a scale or play at your own risk.

    A check weight set is on the way now.

    Got the check weights today.
    Old scale was constantly off:faint:

    New scale was MUCH MUCH better.
    I held off from loading anything till I got the weights.
    45acp.
    4.4 WST with a 200lswc averaged 766fps
    4.7 WST got 810fps.

    Loaded some 40s&w with 4.4 WST and speer 180 JFP's:wow:
    VERY pleasant to shoot and plenty accurate also.

    I feel better now.
     
  17. Now it's right, pretty much what I get in a 4" gun.

    Quick question for all of you loading WST, how does it do through a powder measure?

    Excellent through my uniflow.

    Good deal. I like AA powders because of the way they meter. I think I will pick up some WST to give it a shot.
