    Plunk Test

    Use the barrel of your weapon as a check of your length.Also check that your load fits and feeds from your magazine.:)

    For semi-auto pistols, using the OAL listed on load data won't ensure it will work with your pistol as often test barrel fixtures and not actual pistols are used to measure chamber pressures.

    Also, there are differences from pistol to pistol based on brands/models so OAL that works in one pistol may not work in another pistol.

    For these reasons, reloaders must determine the OAL for a particular bullet that works with their pistol using the barrel drop test (for max OAL) and function test (for working OAL) - http://www.thehighroad.org/showthread.php?p=8864541#post8864541

    I load 125gr TCFP to 1.040" OAL. You're fine.

    The barrel-to-bullet fit determines the longest OAL you can use.

    The load recipe is really the shortest OAL you should use.

    Generally, you are open to choose any OAL between those 2 limits. The manual is not "recommending" anything, they are only "reporting" what worked safely for them. It's up to the reloader to figure out to configure that data around the bullet, powder, and barrel you're working with. WE can suggest, but only YOU can make that final determination.
