It may, but, regarding velocity, on the slow side . . . H-322 (Extreme - ADI) and Benchmark both work well, and are considerably denser than H-4198: with my Jones set to throw 34.7 Gr. of H-4198, it throws a little over 37 Gr. of the former pair. The extra 2.3 Gr. is worth about 100 FPS lower velocity - again, however, both H-322(Extreme) and Benchmark will perform (shoot small groups) at competitive levels.
The Hodgdon burn-rate chart lists H-322 at # 74, with IMR 8208XBR at # 85: between the two, in successively slower order, are AA 2015; RL-10; N-130; IMR 3031; N-133; Benchmark; H-335; RS X-Terminator; AA 2230; AA 2460 . . . I have not compared the bulk-density of the 8208 XBR to H-322(Extreme). For comparison, RL-7, IMR 4198, and H-4198 are listed as #s 70, 71, and 72. Between H-4198 and H-322(Extreme), @ #73, lies N-120 . . .
Since you're looking at the same expansion ratio (30BR), these should prove fairly relative - reduce the bore volume, and the burn-rate chart relativity can - and does - "go all to hell!"
If the bulk-density of the 8208 XBR is less than H-322(Extreme), the XBR will, likely, burn like charcoal - that being about what N-133 does.

I have found that any powder, listed between H-322(Extreme) and Norma 200, has some usefulness in the 30BR configuration. RG
