    I am having 7mm allen mag built and I'm wondering if anyone makes a suppressor that can take that kind of pressure. ...more than 338 lapua powder capacity out a 7mm bore size .. ?

    What is its water capacity, the barrel length, and your load data?

    Do you know what powder will be used?

    I can't replicate that in QuickLoad, but it would be OK at that barrel length in a .338 suppressor, such as our new (not yet released) .338 model.

    How much louder would it be (approx) than a 338 lapua. ....with the bullet size vs suppressor size of 338 to 7mm? And how short could the barrel be before there was an issue?

    I have no idea. It should be pretty close based on the amount of powder (around 100 grains). On the barrel length, I can't get a good read in QuickLoad so I don't have even a semi-reliable predictor on the burn rate

    Thanks ..! And when do you plan to have the 338 one out?

    I know of other LKRM 338 Terminator owners using the TBAC 9 Ultra; they're surely satiated in its use! For what its worth my maximum loads approach 3150 with a 300 grain Sierra MK, Berger OTM, AND 275 grain Peregrine using H50BMG, RL50, RL33, HUS869, AND VV n570 loading from 100 to 113.5 grains (depending on powder of course). The LRKM is a single shot turnbolt bullpup. My barrel is 31" and the heaviest Broughton offers. Princess at camp5.jpg
