Richard,
If you want to follow the saga of the .357 Mag I have, go to this site
http://forums.handloads.com/forum_posts.asp?TID=1061&PN=1&TPN=1There's 14 pages on it, so it covers everything I have done, good and bad.
I am using 10.0 gr IMR 800X with the 180 gr XTP/HP in .360 DW brass right now. Shot a 5 shot group today at 2" and a 1.37" three shot group at 100 yards with that load.
I also shot a .357 load with 250 gr cast gas checks from Beartooth with 9.5 gr Lil'Gun, CCI 400 primer and no crimp into 3.5" at 100 yards. Those groups are posted on page 14 of the saga.
Got my other computer to work and I can post pictures now!
10.0 gr of Lil'Gun in the .357 with the 250 gr boolit is real close to being too much and probably needs to be backed down a little.
Here's what they look like at 100 yards and about 85 degrees.
In case you can't read the group size, it's 1.87" at 100 yards with a cast boolit.
