I was not sure how much Triple Seven 2f I shot out of mine but I looked and did find where I shot it. It worked real good. I save my 3f for my Whites. In 99% of my rifles 2f works just fine.

I would get a new nipple as I do not think they sell the retaining springs. Lat time I ordered a couple was from Midsouth Shooters Supply I believe. You want to try to make your own spring if your handy, out of some wire. I never tried it but thought about it. Also I shoot a lot of Goex out of mine, and Pyrodex RS.

I had stepped this distance off. After I got my range finder, I learned this was only 88 yards. But this is shooting large conicals out of the Black Diamond XR. These No Excuses were the 460 grain and are real accurate as well.
