That can't be the reason!

Sierra lists both H4198 & Win 748 data for this study.

8208 XBR is right, smack dab, in between the two as far as burn rate.

h4198 = 72

8208 XBR = 85

Win 748 = 101

Win 748 is the slowest of the powders tested, and it is the most accurate.

If anything ... the pistol barrel prefers the slower powder.
