UC,
Thanks for the link to the online manual. I will download it, reformat it and print it. As best I can tell the stock is not bedded so I will need to look into that. What type of seallant do you suggest for the inside of the stock?

Indiana Smokepole,
I have around 5 or 6 powders available including the 2 777's you mentioned. I will probably try the 777 3F out next time I get out. Thanks for the other info and ideas.

Sabotloader,
I will download the online manual so thanks for the offer anyway. I do have some 400 grain White conicals I bought some time back to try in another gun, when I ordered them they asked what the bore measured and I think I told them .501 so the ones you have may be larger than the ones I have. If you want to get rid of them I certainly will give them a try. I also need to check with a friend that has a mould for a No Excuses style bullet. I need to find out how big they come out of the mould at, I do know he has sizers for .501 and .502 so they must be larger than that. If they are big enough I may hit him up to let me use it for a few days and see if I can put a dent in the 100 or so pounds of pure lead I have.
