6 x 45 16 inch barrel velocity?

[varminter .223]

I ordered one today and I will most likely be shooting 58 Vmax bullets. I hear that 2200 is a good powder. Does anyone know what kind of velocities I can expect and what other powders might be good.

With 27.9 of 2200 and a 58 VMAX I got 3525 in a 24". Not pushed bad. With a 16" I would look for every bit of 3300.

Nope, my 3 16” barrels with a max load of Benchmark nets 2850fps. That’s 2ARs and 1bolt. Bolt get 50fps more. A little faster with H322 but close enough I went with the more accurate load which was the Benchmark load.

I got around 2800 fps with 70 grain bullets in my 16" 6x45.

Idk what mine is but a 70gr NBT and 26 grains of XBR is mean coyote medicine

Why is this not a more common round it seems perfect?

Because up until it was SAAMI'd a few years ago it was a wildcat with no support. It is now SAAMI and no support. Back then there were bigger cases and no one wanted s small capacity round. It got jumped over in all the new cartridge offerings and will probably never get much traction. It will run side by side with the new 24 Nosler but I bet you don't see that in a gun rag.

So I assume brass has to be fire formed?

Nope. Just run .223 brass through a 6x45 sizing die and that's it.

yup.

and since you're only expanding the neck from 5.5mm to 6mm..... well yea... its a easy-peasy thingy to do

What kind of velocity from 90-100 gr bullets?
And will they shoot?

 

[forty five]

I get close to 2800fps out of my 12.5 inch barrel using a max load of H-322 under a sierra 60 grain HP.
Under an inch at 100 yards.

 

[varminter .223]

27.6 grains of 2200 runs a 55 bt right at 3310. Brass looks great. Getting some right and left but it is awful windy today.

Try AA2015. I did per Mike at D tech's suggestion, and it made both my 6x45 shoot like bench guns.
