Last night I was playing with my White 91 rifle, caliber 375 (or is it .366?) shooting 300gr. paper patched boolits. The stainless steel nipple lasted about 20 shots before it was torched enough to start getting too much leakage. I know I should pony up for a platinum lined nipple from Buffalo Arms ($60), but for as little as this rifle gets shot I am wondering how long the Ampco nipples last? Anybody do a comparison?
The other question - I see Pedersoli touting Beryllium nipples for the Gibbs rifle, are they the same material?
