Thread: Sako Brass

Anyone reloading with Sako brass, the new stuff in components, not once fired factory?
If so are you happy withy it ?

looking about for Lapua Creedmoor brass [hellishingly expensive and seemingly unavailable]but have come across some Sako .
Will be reloading for best accuracy I can get. Planning on a long range Wallaby gun.

No problem with Sako component brass

Have annealed it on the 5th firing in rem mag and another batch annealed every firing

Two minor neck cracks out of 100x brass (when not annealing every time) which is quite normal

I have been using 308 SAKO brass. good stuff so far. Not as soft as Norma

Get Sako ammo for work, give all the brass away, don't like it personally.

Too brittle, thin walls.

Prefer RWS, Norma, Lapua etc.

I’m a fan so far only .223 but

In NZ that means “annealing suitable” and greater powder capacity for more velocity

Pretty sure it's diminishing returns R.E case capacity.

Top of the line brass usually has less internal volume (Lapua, ADG) vs. the cheap stuff (Remington, Hornady).

Brass only flows forward after firing, and guess what happens when you trim brass?

Rather not have a case head separation.

What's the difference between once fired factory and new out of interest? I ran it at max load in a 308 and have been more than happy with it. Used norma and lapua previously in other cals so have a benchmark atleast to compare in the future

There's Petersen brass at Workshop Innovation as another option.

Greetings All,
There have been a few myths about regarding increased case capacity and velocity. Some have claimed stupendous increases in velocity due to changes in case shape and hence capacity but actual pressure tested results have shown these increases have only been gained with stupendous increases in pressure. A few years back John Barsness developed some rules relating to case capacity and velocity based on pressure tested load data. One rule was that possible velocity increases at 25% of the increase of available case capacity. I used this rule, when developing some loads in my 6.5 x 55, to calculate what velocities should be possible and it worked well.
Using the .308w as an example case weights vary from about 170 to 190 grains including the fired primer. 20 grains of brass work out to about 2.3 grains of water or 2.2 grains of powder or a 4 to 5% increase. This works out to 1 to 1.25% increase in velocity or around 30 fps or about what you would get from an extra inch of barrel. Worth thinking about.
