Since this is the reloading forum I'll ask here, but it might get more attention over on the Express forum. My love of the 308MX held out this weekend as I bought a second gun, this time for my 11 year old son. While he can fire full loads from it, I want to develop a practice load. The chamber is not conducive (at this time) to any current cast offerings, so I am bent on finding a load for my son to practice with. I've got the 100gr. half jackets from Hornady and some 125gr. Sierra HP, and 130gr. Speer. I want to make a few plinkers and perused and remembered I could take any Hodgdon load with H4895 (there is available data with the 125gr), take the max H4895 load and take that same bullet with 60% of the powder or more to get a practice load. I came up with a number and increased it a bit to make sure it was stable. this gave me 30 to 32gr. I'm sure that'll work, but wondered, since I was currently out of the H4895, if anyone was brave enough to use H4198. There is no data on this bullet with Hodgdon and the 308MX, but there is a plethroa of it in the 308 Win, 300 Savage and 30-30, which are semi close to the same curves. I was thinking about working up from 26gr. Sound crazy to anyone? The 300 Savage starts with 32gr.,and I doubt I want it going that fast. I've used H4198 up and down the spectrum with pretty good consistency before. (especially with the 30-30. I just don't want another 1# of powder... Incidentally, the 26gr. is the Max in the 30-30. I'm thinking 28 or 30 would be a good area to work towards.

Hey Doc,

Why not just get the RD 165 gr mold and go with it while you work up those light loads for Jack. "...The chamber is not conducive (at this time) to any current cast offerings..." Have you contacted RD? I am pretty sure that boolit is just fine for that .308MX and what you are planning.

p.s. I haven't been keeping up with the .308MX, chambers, throats etc. Also I would be more than happy to send you some boolits.

He is making a new boolit as we speak. Or rather he is waiting on Lee as we speak. I've got 1000 of the Ranch dog 308's sized, lubed and ready to go. Maybe I just need to play with them. Didn't you say it didn't work so well? The neck is so short this boolit gets a little burned...

I think I've got some little Lee 115gr. Soup Cans. That won't go down below the neck. Maybe that's what i'll play with...

Mr. Jack shot a 2.6 inch group that really would have been less if we'd not counted a flyer with this gun (and your scope) and 41.5gr. of leverevolution.
