Hi guys,
This might be in the vast treasures of DB somewhere, but just to "cut it out in cardboard" - as the Danes say, I'd like to ask some specific questions.
I have discussed this a bit with a fellow Dark Sider from here and I would just like to swing it by you.
I remember reading that 13mm inner barrels have the upper hand on dry muzzled guns but now, I am a bit puzzled.
Say, we take two Stens of the same length (both with a 40mm outer tank), one with an 11mm inner barrel and the other with 13mm, add dry muzzles to both of them - then how would they compare to each other in terms of getting the most power out of the guns?
I know a 13mm will have a more powerful shot if the two were at the same pressure, but the 11mm would also be easier to load.
To get equal power out of an 11mm we would have to raise the pressure, which would also make it more difficult to load.
I guess my question is whether, at the end of the day, if we want the same power of shot from each of the two, will the loading effort will be the same and the only difference is the pressure of the guns?
Let's say the loading effort of a 13mm gun is X and the spear leaves the gun with Y energy - would those two values be the same in an 11mm gun?
(Remember, I am not an engineer, so this might be completely flawed)
If that is so, then I guess there are a few pros and cons to take into consideration:
- An 11mm gun will constantly operate under higher pressure. That might not be an issue with a Mares, but as far as I remember Seacs are rated to 20bar whereas a Mares' goes to 30bar.
The trigger pin of a 11mm gun would be slightly harder to press.
- The piston will be lighter in the 11mm. My feeling is that it is a negligble pro as the spear weighs relatively much. But maybe it has a say in how the piston slams into the bumper?
- It has been pointed out that a 13mm inner barrel has the advantage that one could use both 7mm and 8mm spears with an 11mm inner barrel can't accommodate the 8mm spear.
