It did seem a bit dirty compared to H4350, also pretty slow in comparison. I've seen several posts that say it varies quite a bit from production run to production run. Mine must be on the slow end. Bought it last summer when my son, cheesy, bought a Win Shot Show Special Low Wall 6.5x55. I was running low on H4250 and H4831sc, so I needed something in the burn range. I ended up sending him off on his Mule deer hunt with most of the last of my H4831sc.
