john.... so you can bring ammo from here to the US. so can u bring in other stuff like Lake city 7.62 or 556 into canada?

Not sure I understand your question, why would I ship ammo from here to the US ?? Our US dealers are delivered directly from offshore


On the other hand you ask if we can import from the US to Canada the costs are simply too high on that ammo to make it worthwhile .... Don't forget the Can $ is anout 25% below the UD $

HI HITZY;
Perhaps you would be kind enough to show us how to indentify which is which, berdan and boxer,,,WITHOUT taking the ammo apart ??

Have you tried weighing the rounds? Or the full cases? The web might be thicker on one version or the other, changing the weight. Other than weight, if it is not marked on the packaging, I don't know how to tell the difference.

My M305 does not like 308, especially Winchester brand. Rips the back off some of the casings. The brass that survives show definite signs of pressure at the neck. Shoots 7.62x51 just fine. There may be a 308 brand out there that will shoot fine in this rifle but, why bother. I know what works and what doesn't.
In my humble experience, one can shoot NATO out of a 308 without issue. The other way around 'sometimes' causes some issue.

There are differences between 7.62 and 308, but the dimensional differences are insignificant compared to the huge gun to gun chamber differences in the guns of both calibers.

7.62 is made to a set of specifications that includes some issues that 308 does not address. The powder is required to have a lower muzzle flash. Commercial ammo specs are silent on that point. The big difference is that the case head for 7.62 is typically harder (stronger) to resist the violent extraction of an automatic action. When 308 brass gets chewed up by extraction, this is sometimes ascribed to higher pressure. Not so. The pressures of the two flavours are about the same. 308 brass is often softer - that is why it gets chewed up.

7.62 also has port pressure specs, which 308 does not. This can cause 308 ammo to over gas a M14, especially if a heavier bullet is used (slower powder means higher port pressure.)

I hope this is the case (no pun intended), with sturdier brass for this batch of Hirtenberger, as I am a bit concerned after reading a couple comments about it being high octane stuff and maybe too much for an M14, or Norc M305 in my case. Since this stuff should be made under the more strict controls per the NATO spec as you say, I'm hoping the M305 will tolerate it. I've had no problem with the Barnaul steel cased .308 stuff and some similar MFS, but not tried any true NATO surplus ammo yet. Would really like to know that it works fine in a Norc machine.

OH my, will the expert opinions never end....
how do we take into consideration the variable humidity in the wood, no two will be the same....
As for web dimensions, PLEASE note that I said NATO spec, therefore all the same ....

Please let me know how the group buy from Montreal turns out, just in case we can't get enough people from Quebec city.

Will be pleased to help. I may end up processing my own 10 case order. All depends on feedback and arrangements I get from Simonyzer, no news or reply so far.

See above.
 
I'm also organizing a group buy for the Montreal area. Minimum 10 cases to a full skid of 48. Anyone interested let me know.

Ganderite is only trying to be helpful John.

Speaking of helpful, if the younger guy with the tattoos is still working for marstar maybe a trip out to your range with some of this ammo and an M305 would be helpful.
