Go to powder for 69gr SMK in 22-250

[Lefty Trigger]

What would be your "go to" powder for the 22-250 shooting 69gr SMK's in a 8 twist. So far out of the 1/2 dozen powders I have tried the only thing I can get to group is H414 and only with a magnum primer. I have a 26 inch Shilen barrel in a Savage. Just looking for ideas of something new to try.

Ramshot Tac maybe..?

 

[long40shot]

I'd try, Varget, H4350, RL15 or maybe H4895.

I have had very good luck with 3 differnet powders; IMR 4166, IMR 4350 and H414. I only use the IMR 4350 in the winter because of its temp sensitivity, 414 is also temp sensitive. For the most part I used 4166 and was suprised at its accuracy even at very long distances. The 69 SMK is a great bullet in 22250s that have 12 twist or slightly faster barrels. My gun liked them jammed and I shot it that way until the barrel was done.
I need to edit this some. The 69 is not supposed to work well in a 12 twist barrel. I live and shoot at 4500 ft and up here it works great in my 12 twist Savage. At lower elevations it may not stabilize.

Not a standard 22-250, but a friend of mine has a 22-250 Ackley with a 1:8 twist Kreiger barrel. He's getting 1/4" groups fire forming with GI surplus IMR 4895.

H4350 is a great one to start with.

H4350 is a great one to start with.

Yup, I’d try that

I did this several years ago with SMK 69's and went back to my notes-----H4350 produced smallest groups.

This was before the TMK 69's came along----still have the 8" twist barrel and should try
the TMK 69's.

mine is 8 twist and really likes H414

I use AR Comp with 69gr TMKs at around 3150 fps with amazing result .

 

[bullseyeshtr]

I am using 32grs of Varget with a nosler CC moly coated not running them real hot was the same load I used before moly coating them. CCI 200 primer. shoots in the .2"s with my savage model 12 bvss. I think the velocity is around 3100fps if I remember right.

I have a 10 twist and shoot the 69s. H4350 produces great accuracy. CCI 200 primer.

There are probably 10 or so powders that would work for 69 grain bullets in the .22-.250.

I like H4350 & H414. There is a $8-$10 difference per pound. Recent lots of H4350 are apparently faster than old lots so I use about .5 grains less. H414 seems to be affected by high temps like over 90* - sticky bolt lifts & hot days.

I am unable to realize max loads in the Hornady manual using their 68 grain bullet with both H4350 & H414. Loads shown in the Berger manual for 70's & Nosler site are OK & work for 68-69 grain bullets.

I plan to use Re16 for 68 to 75 grain bullets starting with mild H4350 loads.

CCI 200 primers for all.

My old 10 twist did real well with 68's & 69's using H4350.

I’d be less than surprised if you found that 4064 shot well with 69s.

I believe I fireformed cases for a 22-250 AI with a max loaf of 4064 for the 22-250 and had very good accuracy results.

 

[MikeT49]

Plain Jane 22-250 26" 9 twist, near max load of I4166, BR2, 3350fps very accurate (69 TMKs) Note: I used Hodgdon I4166 data for a 70gr

4064 is a REALLY accurate powder in every gun I've ever tried it in. I think folks get a little caught up in the temp sensitivity stuff.
