Wow, yet another "miracle powder".
A new one seems to pop up about every 5 yrs or so. I remember all the clang and clamour over Varget about 16 yrs ago. It is good, but it did'nt make others like 4895, 4064, or 3031 any worse in the same cartridges.

The Shooter's Den in Sudbury has some. Give Dennis a call and he'll ship anywhere in the country...anytime I'm in there, he seems to be sending something to someone somewhere in the country.
Proof is in the pictures. Chronoed the 30 grain bullet at 3628 fps.out of a 26" barrel, MAX VELOCITY SPREAD 4 fps over 20 rounds. (Target squares are 1/2" on a side) Have had similar results in the 223 and about to try it in 204.

If I wasn't already getting one hole groups in my 222 with reloader 7, I'd be trying that powder for sure. I am getting very good groups with 28gr of Varget in my 204 Ruger, but not all in the same hole, perhaps it will be the magic elixir... FS

Ive got a bunch loaded for workup in my 22-250 . According to hodgdon I should be in the Hight 3700's with 55 gr. bullets. It will be interesting to note the velocities at -20C and again at 20 C . Just need a bit of time and for someone to plow a way into the Range !

You aint lyin'. I went and worked up some loads for my .260 today...12" of snow and the thermometer read -13 C :O . I plan to see what i can do with 8208XBR, H4350 and Varget this winter and then compare the winter load in the summer

I usually dont' work up loads the winter for that reason.....If this powder is so stable than I should be able to use the same load spanning a 40 C change.
I temporarily froze bolt in a rifle on a hot day years ago before I knew better...RL-22 is not very stable.....found out the hard way.

Im aware guys, what I should have said was work up my winter loads, chrony them. Then work up to the same loads but in summer conditions to compare.
Not just chamber my max winter loaded round in the summer and see what happens...work up as normal and compare to my winter data

I tried it in my 17 Fireball as well, works great
19grs 8208xbr w/ 25gr Berger
5 shots @ 166 yards (flyer was no doubt me)
3 shot groups @ 110 yards
Looks good. How do you like your 17 so far? I need to take mine out for a drive and get re-acquainted with it.
Maybe I got lucky but I like this powder
I finally tried IMR XBR 8028 today in my 223. Not great conditions -6 without wind chill. Head wind switching to the an east wind. I had already been shooting 308 and 223 for a good hour so by this time I was becoming a bit of a baby trying these loads.
This is using 69 grain SMKs. I hope somebody finds it useful.
Had the following 6 loads to try :
22.5 grs @ 4 shots group = .434
22.9 grs @ 5 shots group = .524
23.2 grs @ 3 shots group = 0.218 (I bolloxed 1 shot ignore as see fit)
23.5 @ 4 shots group = 0.320
23.8 @ 5 shots group = 0.341
24.0 @ 5 shots group = 0.341

What was the distance? From what I've read 300yds isn't too much with the proper shot placement. I like the low recoil and relative quietness of the round. I was hesitant to jump into this caliber but decided to after doing a fair bit of research. I think if more people would put aside their bias and try the smaller calibers, they would find a whole new level of fun in their shooting/hunting experience. Cheap shooting too which is a plus for me.
