    i was using a load in the 243 that used this powder and the 55g bullet, but i think my dog ate my notes. i cant find or remember what i was using. i dont know where i even came up with the load since its not in my books..... since im out of varget at this time, i was wondering if anyone here might have a bit of insight for me.....

    anyone use this powder with much sucess? i like it in my 222, but i dont know if its the best for the 243 or not. thoughts? thanks

    also, how bad of an idea would it be to start from BL-C2 data since they are almost identical burn rates? im pretty sure this is poor practice, but does anyone know if it would be ok in this instance?

    I contacted Alliant awhile back and asked for help with load data for 10X. I was told I could use H322 load data as is. Works just fine.

    I was wondering about using this powder in my 6mm AR turbo improved -- basically a 6.5 Grendel necked down with the shoulder pushed out and angle changed to 40 degrees.

    I heard that the burn rate was too fast, but if you are using it in a .243 Win then that probably isn't true.

    Too hot or not? :)

    I have a pound of RL-10x setting around and am wondering where to safely start with a load workup using 105 gr Amax.

    Any experience with this powder or ideas?
