I gather that. Good to know.The Dominus was originally designed as a full auto 5.56 can. The 30 cal aperture helped with back pressure without giving up to much performance. You can watch the entire surge test on the product page. Anyway, because it was designed for full auto 5.56 first it was verified for magnum cartridges after the fact which is why it has different ratings than the Ultras and Magnus. The Magnus is closer to the 338 in design and strength because it was designed as a magnum can.
Originally when the Dominus came out it was quiter than our Ultra 7. But with the Gen 2 Ultras the Dominus and .30 Ultra 7 meter identical. The Gen 2 Ultra 7 is also lighter than the Dominus now and has shorter magnum barrel ratings. If you are considering a Dominus for hunting, take another look at the Gen 2 Ultra 7.
The baffle geometry must be different between them as well as I see they recommend weighing the magnus and gen 2 338 every 500 rounds due to trapping and holding gas. Any info on this?
Also curious if you can share how you pressure test cans?
