I'm going to be making up some reloads for my AR

Using the above powder and bullets and wolf 223 primers and RP brass

IMR list start at 23.0 gr and 25.3 gr max with a 55 GR. SPR SP

I wont be able to get out and test fire any for a couple weeks

I was thinking of using 24.0 gr mostly concerned if that will cycle the action ok in my AR

It should cycle your AR with no problem.

I use 25.0gr with 55gr v-max bullets. Sometimes i go with the 25.3. I have found better accuracy with higher charges.

Thanks for the information

I made about 200 with the 24.0 gr

I'm going to make some smaller amounts also with different powder levels to also try out

I think Im going to like this powder. Its working prety good in my L&L ap

I agree with ole farmerbuck. I tried H335 with 55g fmjbt's with 23, 24 and 25g and the groups shrunk down to the size of a quarter at 100 yards with the 25g. My 20" AR absolutely loved the 3000 fps that the 25g delivered. I also noted that most factory loads chrono'ed just about the same speed as the 25g H335.

I like using it in the AR's especially when the chamber gets hot from lots of shooting at p-dogs. The hot chamber doesnt seem to bother much. I also like it in the 22-250's with 35.0gr. and 52gr A-Max's.

Is 8208 temperature insensitive?

I recently shot 20 rounds loaded with 22.0 gr of XBR 8208 and the rifle cycled every round. and was fairly accurate...

And I 'think' the accuracy will improve as you up the charges. Or i should say, all of my guns shoot better with the upper loads.
