I'm an engineer and took a course called strength of materials. In the course you learn a lot about shapes, composite members and moment of inertia. How two separate pieces come together has a huge impact on the ability to resist deformation. For one thing steel is incredibly strong. A little goes a long way especially in tension which this is tention. The adapter definitely helps but it will never have the same strength as when it was one piece unless you bind the adapter to the gun somehow. A strong adhesive would be great but torquing it on tight might even be plenty to add extra strength. One way of think about this is a phone book. Hold it by the spine with one hand and the pages sag. Now glue each page together with epoxy or super glue and you effectively have an indestructible brick. When stacking materials you only double the ability to resist deformation, when you bind them together the ability to resist deformation increases exponentially. For my adapter I added some locktite and put a good torque on it. I think this a reasonable precaution. The stronger the adhesive the better insurance you'll get. The main benefit of the locktite is it effectively multiplies your stress on the threads due the lubrication. This is why people who use locktite blindly strip stuff. Torque specs are usually intended for dry application adding a lubricant can double even triple the stress on the threads when applying the same torque. Unfortunately with lubricants it depends on a lot of factors and it is not an exact science but there are some good rules of thumb out there for how much a lubricant will multiply the stress on the threads which also increases the tension in the screw effectively applying more pressure to hold things together.
I Only theories about wall thickness and thread roots from naysayers. Not saying issues haven’t happened, but I can’t find any evidence.
Going light weight and shortening the bbl will help your balance issue. The difference between my ultra 7 and nomad Lt is significant on my 20" 270wsm.
Being that many rifle makers such as Browning, Ruger, Christensen, and weatherby who are known for out of the box accuracy, thread 1/2x28 on some of their rifles tells me this is definitely not a concern. Steel is incredibly strong. You don't need a whole lot. You can hang 5 x F150s from a 1/2 inch grade 8 bolt. Steel is impressive. It could impact accuracy. My gun smith laughed when I asked him that question. He gets that question asked alot and he's never had an issue. Biggest downside to 1/2x28 is most muzzle devices for medium bore are 5/8.
I refuse to shorten a barrel. Most of my rifles are flat shooters and I can't compromise on that. I also hunt in areas with enough trees that 22 or 24 inch barrel with a 7 inch can is just obnoxious. Earplugs are lightweight and they don't get hung up on trees. These are just my preferences. Everyone is different. I like taking long shots on paper and with a good rest I don't mind shooting game past 300 yards. Honestly with a 30 cal 600 yards isn't all that long. Plus extra fps provides quite a bit of room for error and helps with wind. I also prefer a break for magnums, no supressor can do what a nice break can as far as recoil. Again not saying youre wrong just my preferences don't align with hunting with supressors except varmints. If my hunting was close quarters I'd probably be on board.
Youre good to go.
1/2x28 with an adapter is fine. Many people do it with no issues. As far as gymnastics and money I guess that’s all up to the individual. When I had mine set up for 5/8x24, I was sending them off anyways to get done, it was 30.00 more to get shouldered for 5/8x24 than it would have been to just get 1/2x28. I figured if I was sending it off anyways, I’d just get exactly what I wanted. I had 2 rifles done that time so 60.00 more (I just spent more than that on mid grade sushi in the anchorage airport) for exactly what I wanted.
