I will say I am impressed with XBR, I hope they keep making it, it sure did wake up my old Krieger barrel on my Savage, and I have a hard time seeing a difference with it and N133 on my Bat with a Brux barrel.

I will say this I have played with the old IMR 8208, and the new stuff at the same time, and they are as different as night and day. The old IMR meters different. You can only get a little over 30 gr max in a PPC case. The XBR will go 32 grs. The old stuff seems to be much faster burn rate. It seamed that I could not get enough XBR in a PPC case to cause a pressure sign, not true with the old IMR. (I could get pressure signs at a hair over 29 grs)
