Help please locating canadian made reduced capacity 308 cases

I can imagine what you're describing, but I have to ask... what's the point? If you must use a standard bullet and primer, why not simply load one of the many reduced or very-reduced recipes available in a standard brass casing?

I've even come across some loads using very heavy lead bullets and low powder charges with filler that were substantially sub-sonic, IIRC.

Agreed. Uber expensive custom made cases .... or super cheap 10gr Trailboss loads in conventional cases. Same end result ballistically. Not so same financially.
 
- pistol powder goes along way, much more than trailboss!!

reduced loads with trailboss that are only at partial case capacity tend to show velocity/ poi changes in big temperature changes

Weight wise you are gonna use about the same regardless of the powder.

The velocity changes are most likely due to the powder distribution in the case. TB goes a long way to alleviating that. And you could always use a small amount of tissue paper wadding on top of the powder if it is an issue.
 
I can't help but ask, why not just shoot cast??

13 grains of red dot and a 150-200 grain cast bullets has served me well for many years in all of my 30 caliber military cartridges.

And as for trailboss having changes in poi and velocity that's common with reduced loads. Way to fix that is stuff a small amount of a filler like dacron into the case after you put the powder in. The dacron holds the powder against the primer and really helps give uniform velocity.
 
If you have some of these cases, I'd like a couple for my collection. My PM is disabled. email me direct at cronhelm@shaw.ca
Thx

I would like to see pictures and know who makes them.

And cronhelm, I'll be damned; that's where you were hiding instead of expanding your pages, CGN :).

Thanks members for all the info.
the cartridge cases I am talking about are very close to the brass ones with the smaller inside capacity shown in the german links on page 2 of this thread
wish I could read german!
still looking for the Saskatchewan guy who was making these cases

Back in the day we used to resize 308 brass to 7BR for use in the Remington XP100. Dies were available to push the neck back to about an inch and a half, trim the long neck and then resize to hold a 7mm bullet.
 
I forget where I read it, but, there was an article somewhere about subsonic 7.62x51 rounds for Vietnam (?) where the manufacturer placed a small bit of rolled up cardboard inside the case, allowed the cardboard to unfurl inside the case and hold itself against the outer wall. Then powder and a bullet were added.

I have no idea about what kind of powder it was, but probably not a charge of fast burning shotgun powder. I have no idea when the idea of using shotgun powders came into general knowledge for reduced loads.

As for the cardboard smoldering and lighting fires, or causing problems for reloading, I don't think it was high up on the list of problems for the military in 'Nam.

Anybody else hear of this idea?
