Short barrel ARC powders

[KY_coop]

Ive had some great results recently trying out the vihtavuori powders in my nrl 6.5 creed and 284 win rifle. I would like to try some out in the smaller cartridges ive got but im not to knowledgeable about burn rates. What would the best options be from vihtavuori for SHORT barreled 22/ 6 arc?
16" 22 arc 75-80gr bullets
18" 6 arc 103-108 gr bullets

Edit: both are bolt actions so I can push the pressure a little bit compared to most available load data.

Look up the powder burn chart and find the closest VV powder compared to what you already use.

N555 and 560 is what ive used for my 6.5 and 284. I figured they both would be to slow to get good results considering the short barrels. My current best load in 6 arc uses h4895 but haven't loaded for the 22 arc yet

That's my bad, I initially read 6cm not arc. Again, check the powder chart. The closest VV powder to H4895 is N530. The Hodgdon load data site would be good to check too. Lots of people using lever powder in that case to get some speed. Heard about some people using Staball Match too.

That a bolt?

Yes

@Gstew1930 do you mind sharing more data on your load? I was able to pick up a pound of N540.

Running a 6 ARC straight pull ULUL 16” barrel so obviously I will need to back off your bolt load more than just dropping 10%

Hornady brass 1x and CCI BR4 typically for me. ASC mags.

Thought I would update. 6ARC 16” Bear Creek barrel on a side pull upper no gas. I settled on 28.3 gr VV N540 with 95 TMK at 2625 fps. Some cases just get a little shiny spot on the head but all extract fine and I don’t have any caming leverage like a bolt.

That out does factory 108 ELDM by a little so I’m happy with it. Stocked up on a few more pounds of the same powder lot. Have another 100 bullets to load and going to take it to some distance and see how it holds up.

6 ARC, Bear Creek Arsenal 18" bolt action. less than 100 rounds thru barrel.
I loaded a bunch of Hornady 80 gr ELD-VT this weekend. Used 32 gr of Lever. First 3 shots were
2975
2962
2955
Primers a little flat but nothing I would not push further.
This is about 90 fps faster than I was getting from factory (speeds were all over the place) but handloads are tighter groups. In fact the tightest I have shot in this rifle. Not as tight as my Ruger American 7.08 but it's a start!
