    I use a Lyman 410610-GC mold that I cast for use in my .41 Ruger 3 screw .41 Magnum and Henry 41 Mag Rifle. The Sage Gator gas checks for a Lyman mold worked as advertised. Very well.

    Worked really well with the Lee .410 cal bullet sizer I utilized...*simply a heads up, make sure that the cast bullets that you add these gas checks to have a bevel at the base of the bullet itself, not just a square/flat base.

    Extremely great service from the Sage team as well...great product and service...what else can one ask...

  6. .41 cal. Lyman size gas checks 5 Star Review

    Posted by on May 31st 2018

    I have a .41 caliber custom mold made for Lyman gas checks. It a rifle bullet for a .40 caliber rifle, I shoot it in three different 40-65 rifles. Since Lyman quit making that size, I have had a difficult time finding checks
    to fit bullets from this mold. These work and are very good quality.
