I don't have enough rounds on mine to comment. I'm using AR2208 (Varget) and AR2209 (H4350) behind 105gr Berger Hybs. I have a short freebore - .104". 32.5gr Varget and 36gr of H4350 shoot to exact same point of impact at 100m.

Those using H4895 (AR2206H in Australia) any comment on the below thread? A number of dasher shooters in Aus appear to have increased throat wear running that powder - it appears contrary to Josh's experience stating Varget was torching throats.

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 Varget barrel life was better but at an increased maintenance rate that I wasn't a fan of.

I run IMR 4166 currently and I'm liking it a lot. 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.

This is why I love this sport. Gunsmiths who take the time to share their experiences and knowledge. I appreciate everyone else's replies as well. This is a great place for me to start. Looks like I'll be picking up some IMR 4166 to try along with as much varget as I can find.

Thanks guys!

What about RL15?

What kind of max load with the IMR 4166 for the 105 and 110gr bullets?

Thx

Several folks out here shoot jlk. I hear that they are the next step up from Berger/Sierra etc. in all aspects. But you have to order ahead and get enough to last. It’s a one man show.

How are the 105 JLK's compared to the hybrids? Doesn't seem like many people run the JLK's.
105 jlks shoot great! They used the same exact powder load in two of my dashers as the 105 hybrid and at the same speed. However they shot considerably slower in another barrel (3 groove) compared to 105 hybrids with the same exact charge. Either way they shoot well jumped .015-.025. Brian Allen and the Allen clan exclusively shoot JLK bullets. Dan Bertocchini shoots the 110s inhis dasher and gets phenomenal results. It’s crazy how consistent their base to ogive length is and you can see those results with how consistent you seat and group. But yeah order now don’t hesitate and expect 2-4 months of waiting

In my rifle, NORMA DASHER BRASS,110 SMK, 32.8gr Varget, CCI 450. Throat is eroded .060+ so my CBTO Measurements are no help to you. I have very good luck jumping them a ways.

Best of luck!

Any load info with the 4166 ? I loved it in my 308 for years

Officially gave up on the Varget . Way too much carbon.

Anyone has solid data with IMR 4166 or any other clean good powder for the 110 SMK?
Waiting on my 8-lb jug of 4166 to get here, but I'm planning on doing a velocity ladder with 105s in the same range as varget, probably 31.5-33 grains, CCI 450s.

Start lower with 110s, maybe 31-32.5? Depends on how hot it gets in your area.

Probably it will run 2850 to 2900 but I'll know more this weekend.

Very interesting - i run 4895 currently as Josh turned me onto it. But seeing the 107 loads here with 4166 very interesting. I am shooting 110s .. I love them in the dasher. Need to get a bottle of 4166 for the 110s I think.

What action, barrel length,speed ,and what freebore/reamer , I also shoot 110s in Norma Dasher using rl16
Bought used bbl action - Defiance Deviant, 25” Bartlein M24 contour, speed is not a concern- accuracy is. Reamer?? Was cut for Lapua brass but the throat is so eroded I can safely use the longer Norma Dasher brass.

Interesting, I know throats erode but I have never heard of any throat burning up enough to increase 50/1000 in length AND 30/1000 in diameter . That’s crazy
Speed is a curiosity as not many people use Norma Dasher brash so not much of a benchmark to compare.
Thanks

The throat diameter has not increased .030, maybe .003. The length has increased .050-.060”, maybe more. Still shooting great!
A guess at velocity is 2800+ as it shoots right with everything else.

Does anyone have h4350 data?
You can go up around 36 grains, for me it was a pain to get it in the case(too full) and didn’t offer anything more in speed or accuracy, my barrel is 24” possibly beneficial in a 28+
I found rl 16 to have better velocity, less pressure, and more accurate, 34.3 grains for 110 smk
35.3 for hybrids 2880 and 2960 respectively

Finally got out to do some load work up. Specs are Bighorn TL3 w/ 26" Kreiger barrel capped with a 30 cal Titanium phantom supressor. H4895 under Berger 105's.
These were once fire formed Lapua brass.
Charge Min Max Avg. SD
31gr 2881 2913 11.7
31.2gr 2912 2925 5.6
31.4gr 2920 2949 2932 11.9
31.6gr 2936 2947 2942 4.1
31.8gr 2955 2982 2967 10.0
32.0 2971 2988 2988 6.9
32.2 2994 3007 3001 6.3
32.4 3011 3022 3017 4.6
32.6 3013 3039 3028 10.2
32.8 3044 3063 3052 6.8

This was a cold day at 5760 elevation. Definitely not my best day shooting but with this I can start to see where I go next. 32.8 was starting to show a slight tension on bolt lift but not bad. I'm looking at 32-32.4gr playing with seating depth.
Out of curiosity, is that's the Cheyenne Mtn range?
