Hey everyone,

Long-time lurker and first-time poster.... hoping I'm not beating a dead horse here with this question.

Currently trying to build a lighter weight western/mountain hunting rig. My sets are currently set on the Weatherby 307 Alpine 7MM backcountry. 16" barrel and lightweight is what I'm looking for (that would get into the low 20"'s with a suppressor). My question is, is a CGS Hyperion K .30 cal can compatible with this cartridge? I've reached out to SilencerCo and they did not have a definitive yes or no for me, and I have had no luck in a response from CGS direct.

Changes my build a bit if I'm going to need to buy a suppressor specifically for it - and may have me leaning towards a different setup if so.
 
My son and I hunt with 280ai, his a Weatherby backcountry myself a Cooper M92. Use Hyperion and Hyp K on the rifles with no issues. K is a little louder but doesn’t startle elk at 300 yds. The Hyperion on the Cooper is a little long but usable.
