Imr 8208 xbr

This powder may be great in more than the PPC. Yesterday, I received a pound from Hodgdon for testing. It has been shown to be effective in the 6 PPC by Jim Carmichel and Lou Murdica, but would it work in the 6mm Dasher with heavy bullets?

Not having the proper data, I loaded 10 rounds with 31.5 , 31.7, and 32.0 grains to test over the chronograph. I used H4895 as a guide. The 31.7 and 32 grain loads seemed too hot, but they both shot well at 100 yards with the 105 Berger Target. I did not use wind flags, but got an excellent 3-shot group with the 31.7 gr. load. See attached picture. Good shooting ..James

CAUTION: The loads listed above may be too hot in your gun. To be safe, one should start at 31.0 grains. I measured the webb expansion and there is noticeable expansion of the 31.7 and 32 grain loads. Although the loads are accurate, one should start at a lower point and work up.

jd, have you cronied 31.7 of h4895 in the same rifle? and would you have called it hot also? just curious, i thought i seen on 6mmbr this stuff was going to fall between h4895 and rl15. and of course walking into a store and seeing a pound to try is likely not going to happen up here in the sticks.
thanks,
tom
 
It seems hotter than 4895

Yes, I have shot H4895 in this barrel without problems. The 8208 seems to be quite a bit faster than 4895. I am now going to run some PPC tests and see how it compares to N133. Good shooting...James
 
I'm looking forward to trying 8208 XBR in the 220 Beggs. I'm thinking it just might be the ticket.

I have shot it in the 6 PPC

It is very accurate, but it takes 31.0 grains behind a 65 grain bullet to obtain 3320fps. This same 3320 can be obtained with 29.3 gr. of N133 in the same 21 inch barrel. My initial tests show that it is going to be a great PPC powder. The attached photo shows my first three 4-shot groups in a Bartlein gain twist. Good shooting....James
