I'm not certain, but I think with trail boss you may struggle to get enough in to run them at the velocities I was looking for.

Edit, just seen Pommy's reply, so obviously Trailboss is an option...

Yes my reasons were for reduced recoil for little kids mainly, I also like experimenting for the sake of it to a lesser degree ;-).

My 8 year old daughter didnt like shooting full power 223 55gr...

Yes H4895 is often used for reduced loads in any cartridge that Hodgdon lists normal load data using that powder. Can go down to 60% of the max charge.

In my testing with 7mm08, 260 rem and 223,...

NO Don't do that.

You cant run that light with any powder. Imr 4198 is the powder that remington used in there reduced recoil youth loads.

Other powders could be very dangerous.

16gr gave 2350 fps and 18gr gave 2594 fps. Those two powder charges werent quite as tight on the grouping but still quite acceptable at .6 inch, the 14gr load was .3 inch!

Yep ive downloaded 223 55gr to around 2100 fps very accurately using 14gr of IMR 4198.
