The increase in shroud stiffness should be about 8 times higher when comparing 38 mm against 25 mm with the same wall thickness.Īt what shroud ID does the airgun look silly? That is a matter of opinion. I could calculate this for specific barrel ODs, but am just trying to make a point in principle. And barrel outside volume is more significant with smaller shroud diameters. However, its weight increase is proportional, as in 1.5 times higher (for the same length) while its volume is 2.25 times higher (less barrel volume). But the added weight of a larger thin wall tube may be worth it: One reason to make the shroud "thin" is weight reduction. You know that they are developing CF barrel stiffeners that replace their flimsy shrouds? These are used with large screw-on LDCs. I can only speculate about the FX shrouds. I look for specific clues to help me identify the key that unlocks the rest of the data. I just have a particular approach towards making sense of things that is rather intense. I would never claim to know more than anyone else. mega-monster silencer specifically fitted to the Impact and the Leshiy 2 - it seems like they felt the same. When Huma created the "Hornet" - their 2" dia. (3) Also, did I mention bigger diameter barrels/ shrouds look better (to me, at least). test this thin shroud and saw no major improvement in sound supression with thicker shrouds? ❓ with a 700mm barrel) - and to the point of this thread - (2) they can gobble up less air, especially with the enormous power that the increased plenums and other power-pixie-dust are now producing. Why does FX (and many other PCP manufacturers) make shrouds so THIN?!? That way they are (1) flimsy (flop around like a noodle, esp. I'm always on the lookout for comparative silencer tests that will give us a better idea which models (or which types/ volumes/ lengths) are likely to work best for our personal applications. Wow, Peter, you know so much more about so many things than I do - cool! □□
