Jim, I have had good luck with te Lee 225gc mould I bought last year from the old shooters.com site. I used 16 grs of 2400 and it seems to be very promising. 16 grs seems to produce a pretty respectable "crack", I have not chronographed it yet. So far I have only had one chance to try them out, and I was shooting from cross sticks in the sitting position, and suspect it will do much better off the bench. I bought a .325 sizer to size and seat gas checks, I didn't try any without the gaschecks so cant advise on that. I lube with my own homemade blackpowder lube and seems to work fine. I am shooting these in a Turkish Mauser. I also seat the bullet out so that the entire first grease groove is exposed (no lube in this groove), and the rifling is just engraving the bullet when it is chambered. I have another 20 loaded up with 2400, then will give 4198 a try next. I home to get to the range again in the next few days and will post on it again. Tom
