Many thanks for your help and info, due to a serious illness in the family my range trip didn't happen but I will be going for it shortly. I respect very much what you say and will try the 390 grain hollow base RNL bullets but I am going to reduce the charge to 110gr of Swiss 2f. Got talking to a friend from the Vintage Arms Association who shoots a .500 BPE DR and he advises against using hollow base heads because of increased pressure problems?? My gut feeling is to go for it and see what happens! I will also load a few up with 48 gr of IMR4198 and a foam filler (as supplied by Kynoch) and a 300gr gas checked RNL. Isn't it amazing how much DR advice there is out there and how much of it conflicts with what other 'experts' think!! I will listen to you on this. Pics of the Lawson DR to follow in the next few days.
Cheers
Garry.
Dont forget a thinker wad on the 110gr load, should also get rid of anny pressure problems due to the cup based bullet (i think).
