Go to stevespages.com/page8c.htm He has data for the 22-243 Middlestead, which may be close, and the 6-350 also. Lots of data for lots of calibers. I cannot imagine how much shooting he has done to gather all this data.
For the 6mm I would use Ramshot Magnum.
Thats what I use in my 6-284 with excellent results.
Do a search on the 6-06.
I thought there were some posts in the past on this site.In fact I think Kirby has some info on it.
If you give me the water capacity , bullet and oal of each of each 6mm I can give you some ideas.
Thanks but not worth the trouble. I'll just use the 6-284 info and work from there. I have been loading 64 grains of RL22 on the 6-06AI with 85 grain ballistic tips and it is really accurate. Don't know what the fps is though.
should be about 4150 fps.
