I have been shooting a starter load of 38.0 grains of H380 in my 22-250 Encore. I was using CCI Bench Rest primers and I noticed what I consider to be too much fowling in the barrel...looks like a bunch of unburnt powder laying in the bottom of the barrel.

At any rate, I noticed in a Speer loading manual that they recommend Magnum primers for all Ball powder listed in the 22-250 load section.

So I bought some magnum primers....still seems to be a lot of "powder" left in the barrel.

SO, I HAVE 2 Questions:

First, what is a cleaner powder, and

Second, what powder gives the best overall performance???

I would suggest trying either H 4895, Varget, or N 140. They all burn pretty clean and have worked well in several 22-250's for me.

Varget is going to be hard to beat.....Its about perfect for the 22-250 and it is a stable powder so you don't have to be too concerned about temp. changes...Its all I use in my 22-250....Good luck....George

I'd have to put in another vote for Varget. Quite impressive how clean that powder seems to burn, and in other rounds as well.

ZZ,

Varget works well. A near max load gives me consistent results with a clean burn in my rifles.

I am not familiar with the Encore what is the barrel length? Anyone have any thoughts on barrel length and powder burn in the .22-250??

Kind regards
Carl

I have a 26" heavy barrel on the Encore 22-250.

On the Varget and 22-250 round, what primer are you guys using???

i must be living wrong or something. I hate Varget. I have not had the luck with it that everyone else seems to. I like the way it meters, but beyond that, NOPE.

My 22/250 powders have settled into IMR 3031, RL 7, RL 15, IMR 4895 and IMR 4064, and IMR 4198. Honorable mention goes to W 748 when I am out of the other above listed powders, as does H 414, with heavier bullets.
All the above mentioned powders give me much better accuracy that Varget or H 380 ever do. Don't get me wrong about H 380 as it is one of my ' to go to " powders in several other calibers.
This experience is based on 4 different 22/250s.
Two factory Rugers and two custom barreled rebarreled Winchesters, 3 heavy barrels and one sporter weight barrel.

I must just live in the Burmuda Triangle of Powder Luck.

Cheers and Good shooting

VARGET MAN VARGET!

Try loading 39gr. H414 with a cci#350,which is a large magnum pistol primer.ww brass. Seat bullet about 1/2 turn of die off the lands. I shoot a ruger#1b.I really don't know how clean this is but I shoot till the ground squirrels are gone or it gets dark and dont lose any accuracy. Doesnt seem like its real bad when I clean it. Let me know if it works out for you.
