1/4-28 Threaded platinum lined nipple only uses standard nipple wrench. Platinum lined nipples are a must when shooting heavy bullets with large charges such as I use in long range (1000 Yards) muzzleloading matches. These will withstand pressures generated by these loads without eroding for a long period of time. I have over 1000 rounds fired with 90+ grains of Swiss 1 1/2 F black powder and they are still going strong. I can only get 30-40 shots out of a standard nipple before it is worn out making a platinum nipple far better and cheaper in the long run. The rapid wear in the standard nipples means that each shot is different and materially effects the accuracy of your rifle. Hole diameter is .026".

You are correct, nothing new on using Platinum as they did in the 1850's. Mine have lasted years and 1000's of shots. Don't recommend using 3F Swiss. They certainly look original as well in a vintage arm.
