Who uses H4895 vs Varget? I started initially using Varget (60ish rounds) but am just now finding out about h4895. Seems to me from my light reading it runs cooler and isn't as prone to torching throats? Is this correct?
 
Most guys run Varget. I’ve tried both and both shot good, Varget slightly better in the current barrel. Barrel life difference is minimal I would think, no advantage to H4895 since both are about the same burn temp. Find what shoots best in your gun and run it.
 
I run IMR 4166 currently and I'm liking it a lot.
I ran Varget. It was very inconsistent in lot to lot burn rates, enough that I was struggling to keep a load in tune with it. I had issues finding Varget and when I could get a couple pounds here and that that was good but tuning a load every 250-300rds is why I got away from the other 6's I shot. The Varget was also prone to producing nasty carbon rings in the throat that had to be consistently maintained or the thing would start shotgunning.

I also ran H4895 and it was super accurate, very easy to load and plenty temp stable. It's a little on the fast side for the 105's adn definitely too fast for the 110s/115's but it was available and I could get 16lb of it in a single lot, that was enough to have the barrel mostly smoked (2800rd).

The 4166 gives me a little more speed than the Varget, less pressure than both Varget and H4895, it doesn't seem to be anywhere near as prone to carbon ringing a throat like Varget was, and it's readily available because it's produced domestically.

What powder charge weight did you use for the IMR 4166? I currently use Varget but can't find it anywhere. I currently use 32.7 gr. of Varget for my 6 Dasher. I shoot the Berger 105 Hybrids.
 
I have had great luck with IMR4320,IMR4895 and H4350.
For some reason Varget isn’t that great in either dasher.

The H4350 is a pain to get enough in the case, but does really good.
IMR4320 is the Best but its discontinued unfortunately.
