Sharps 4590, Vic:
In the Oct-Nov 2002 Handloader "Loading the 500 Express", pg 43, Mr Seyfried says "I cannot warn too strongly against using any kind of cereal, plastic or foam filler. While a little foam worm looks innocent enough, I know of two very fine double rifles that have been ruined with foam filler." That got my attention, so I wrote him and asked about Wrights book. He is not to enthused about some of Wrights ideas and like me has yet to find a form of foam that behaves as Wright describes, ie, turns to a fine grit. I've used dacron for a few years and have seen no visable signs of problems, however until recently I have not used as much as Ross advises, which is a lot. I need to get back with him on using 4198 in my 577/500. My one, and so far only, attempt to work up a smokeless load for this rifle showed more of a flattened than I liked. The rifle is nitro proofed but still I don't want to ruin it. Have you had any luck with these loads?
Best.
