If you look back in the archives you will find that I bought some new brass for my 1902 Webley in 375 X 2.5" from Horneber. You may want to search under Oldbrit for my postings about that. Converting from any other calibre required more work than I am equipped for (i.e. a lathe).

Since then I've been loading the Horneber brass and I have no complaints about his quality, only his delivery times. It you're going to buy from him make sure he's got the brass in stock before you part with your cash.

I got the best results with Reloader 15 and had no difficulty matching factory ballistics (see below) with gas checked cast bullets. I've also tried AA2520 but it's very fine grained and I felt that I was getting powder into the primer pocket. A square of tissue tamped down into the case prior to charging with powder fixed it but it's a fiddle I don't need. I've also had good results with AA5744 for reduced loads in my single barrel rifle. I am going to try IMR 3031 sometime but haven't got around to it yet.

I also obtained a small supply of original Kynoch ammuntion made in the 1930s. One of the five round boxes was open with only four rounds in it. I pulled one and it indeed had a 270 grain bullet and 40 grains of Cordite. I shot the other three off and found they averaged about 1950 fps with a low velocity spread. When I have time and the patience to figure out how to post pictures I'll list photographs of the rifle and the ammunition.

Hope this helps.
