    Thanks for the tips. Its nice to know what to expect. I see now why the SAPSF rule says: "Equipment failure due to the nature of the sport (powerful loads, large number of rounds fired) is a standard occurrence."

    I have a Taurus 66CP, 4" with the ported barrel.

    I think that those loads are excessive, both for the pins and your revolver.

    A 180 PF load should work decently on pins in decent condition. When the pins get shot up and heavy, a little more oomph might help, but I prefer a 44 calibre for that. Personally, I would not go over 200 PF with a 357Mag.

    Well... The quote seems a little out of context here. Let me try to explain: The top pin shooters do manage to shoot a gun to bits occasionally. We have seen gun breakages in matches. This does not happen every day, but often enough to warrant top competitors to have a spare gun, just in case. Mostly the failures are repairable, but not on the range.

    I have seen the following (hand-)gun failures on the pin shooting range:
    1. Pistol barrel breaking off, just ahead of locking lugs. (Only 1! This was a quality FA with very high round count.)
    2. Extractor failure. (Seen a few.)
    3. Sear failure. (Once.)
    4. Bullet stuck in barrel. (Mostly from shoddy reloads (often), but 2 from factory ammo.)
    5. Overload causing case to stick in cylinder. (Twice.)

    The first 3 are wear and tear related. The rest are actually ammo related, but put the gun out of play for a while.

    Decent guns are expensive on this side of the Atlantic. Responsible shooters do not assemble dangerous reloads and shoot them willingly. In fact, the SAPSF rule book forbids any dangerous loads. What we are talking about here, is loads that will eventually cause wear on a FA, due to a high round count. And yes, they are not "soft" loads, but never excessive...

    I tried all kinds of combinations for pin shooting.

    Colt gold cup .45 very hot
    S&W 627 .357 mag
    Caspian 9x23 (Hornady 124 gr XTP at 1580 Fps)
    Taurus 608 cylinder machined to accept 627 full moon clips
    Various 9mm's for 9 pin

    Eventually I Sold the S&W 627(it hurt me) and replaced it with another Taurus 608
    I gave up shooting the .45 as the wear on it was significant

    I found shooting only 2 guns to be a great advantage
    Ie I used the Taurus 608 for all the 5 pin and 8 pin events and a 9mmP (flavour of the day) for the 9 pin events

    Reviving an old thread as I started loading 180gr frontier with S221.

    Would someone please be so kind as to confirm muzzle velocity / PF on 180gr or theoretical max muzzle velocity(the loading program guys)?
    The current load works ok but I want to know if it is safe(necessary) to bump it up a bit more?

    Here is my current results :
    S221 Batch 216/14 Dev-0.3 9.4gr
    180gr frontier fp cmj
    38spl case
    oal 40
    Taurus 608 6"

    Chrony Data :
    Lo: 1057
    Hi: 1134
    Ave: 1090
    Es: 76.44
    Sd: 29.39
    Shot speed: 1085; 1128; 1134; 1086; 1127; 1063; 1057; 1063; 1091; 1069

    The problem with modeling your load on QL, is that the QL database does not have the Frontier handgun bullet file. So now you have to take some other bullet and substitute. This is not so easy, as the substitute needs to be a very similar CMJ. I would not want to go there and make predictions.

    Having said that, I do expect the quoted load to be within safe pressure limits.
