Training does not magically turn a non-barrier-blind bullet into a barrier-blind bullet - in those situations where a barrier-blind bullet will make a difference.
But training, of course, is what will get either bullet on target in the first place. Personally, I'd rather the services use a cheaper bullet that sometimes fails than a significantly more expensive better round IF (and only if) the money saved is used on more training ammunition.
The earlier comment about the new M855A1 not fitting into the safety zones of existing ranges is a pretty big deal. Lots of money will potentially be spent to move dirt, relocate range roads, etc as a second-third order effect of this ammo change.
So what if regardless of the round settled upon, troops trained with M193, more training was afforded due to the lower cost, and zeroes were adjusted in-theatre?
Wear would be a non-issue.
Training would be increased.
Cost would be decreased.
No changes to existing facilities would be required.
Am I missing something?
When produced in quantity on SCAMP, there is little cost differential between M193 and Mk318, so why train with one and fight with the other?
