Thread: 22.250

What is the best powder for a 55g projectile in 22.250?

mine likes AR2209. I use Hornady 55gr SP's and Federal Match primers. Easy thumbnail group at 100m with no real load development. What made is the rifle? Do you know the twist rate?

It is a tikka t3. 1-14 twist was using win 748 and serria 55g gamekings but not getting very good speeds from it. was thinking of trying BM2 or 2208. Any throughts

They really honk with W760. I used 40 grns, but that's up there.

748, BM2 and 2208 don't look like they would have too much difference in speed.... how long is your barrel?. what speed were you getting?

It is a 22in barrel. I was using 36.5g with fed primer and hornady brass. The avg speed was 3359 fps.

that is quite slow huh!! yea try a slow burning powder like 2208, 2209, W760(2209 equivalent)

36 years ago I bought a Tikka 22.250 and started reloading for it with 34.5 gns IMR4895 and 60 gn pills. Shot like crazy up until about 4 years ago when I had problems getting 4895, so tried Norma 201 - shot like crazy. Ran out of N201 last year so tried both 748 and 2206H, both shot like crazy, but the 2206H clocked in at 3623fps so 2206H is now my go to powder for the 22.250. That Tikka can still put 5 shots under the magic inch!

That and 60 grain partitions would be a deadly combo on most game in nz

What load with the 2209 do you use and what speed you get?

my t3 varmint loves 35.5 of 08 pushing the 52 g amax at 3680.that is a 1/2 moa load.
A mate and myself and our kids shot 125 magpies out to 290 last week for the ohignaiti kids hunt.
the little fxxkxxs thought they were safe but the dirty old 22-250 sorts them out!

good effort!!

I use 2206H in mine. works well.

Loaded some up after work at 37.3g of 748 an extra 0.8g. Avg speed went up 208 fps with a avg speed of 3567 fps. Alot happier with these results
