I love the .25 acp breech plug i made for my Encore , No more blow by or carbon build up in the BP . Never had a mis fire and small rifle and pistol primer are showing up everywhere around here . Going to a .25 acp Bp and 777 has given my the best groups i have ever got . I have a 100 brass and around 800 primer now . Well worth the $$$$ to me !!
