I've used a musket cap nipple on mine and now have the 209 primer conversion. The musket cap is hotter than #11 nipples and works well,but I do think the 209 conversion is worth it. If you decide to try the musket caps, PM me. I have a new spare musket nipple or 2 setting around that I would send you. If you go #11 again, get a stainless nipple.
