I don't follow this at all.
How did you come to the conclusion it was the chassis and its lack of stiffness that is causing the POI shift with suppressor?
It seems like you are inferring that the forend of said chassis, and its relative lack of stiffness, is what's resulting in the POI issues. The forend should have relatively little to do with any POI shifts - unless your barrel is flexing enough to make contact with the forend (but that's not really a stiffness issue).
The forend should be free floated and isolated from the barrel, its stiffness (or lack thereof) should not be a determining factor for POI shifts.
I can understand why this reasoning exists in the industry but it's not true. The soft (not stiff) handguards cause POI shifts in several ways:
1) Bipod loads are transmitted through the handguard and a soft handguard will put different loads into the action and the rest of the way the rifle recoils. Inconsistent bipod loading will generate strange POI problems. The softer the handguard is, the worse these problems show themselves. IE, a shooter with average bipod load consistency will see larger problems with a soft handguard than a stiff handguard.
2) Certain chassis designs make this situation worse because of how the handguard attaches to the center section and the load is directed through critical areas. Two examples that I think are particularly attrocious is how the Ruger RPR and the Tikka Tac A1 do it. The RPR runs all the handguard and bipod loads specifically through the barrel nut and the receiver is pretty soft flexturally. This means that a bipod on a long lever arm (bipod legs and back to the receiver face is a pretty long diagonal to torque on) gives you really wild performance. Someone who can shoot an RPR really consistently in a lot of conditions and a lot of positions is doing a really good job with BRM. The Tikka runs the handguard to a mounting bung which is screwed to the face of the center section and the scope rail. The scope rail is held on with a few small screws and we're adding the torture of those screws from recoil impulse as well as bipod load now.
I've seen a guy swear up and down that we made him a bad RPR prefit. His BRM was attrocious. I sat down, dry fired it twice, then shot a 5 round group with his rifle and ammo at 600yd that could be covered with a playing card. Another friend of mine in WA state did the same thing to help a guy. That rifle may be inexpensive, but it's not a forgiving platform to shoot long range for a beginner. A lot of what makes it difficult to shoot consistently is how the loads from the bipod and handguard travel directly through the receiver.
So, still Curious to see what everyone’s experience with the PVA osprey carbon barrels are…
The performance in the industry is pretty darn good. Hells Canyon is using the Osprey as their primary core for their barrels now unless a customer specifically asks for something else, we've delivered almost 500 cores to them since the beginning of the year and they're doing great.
We also have HCA doing the wrapping work for us with a specific layup to our core contour. I know this is me tooting my own horn, but the results have been really solid. They've been wrapping for us now since about a year ago and the relationship has been excellent.
Plus your gunsmith can order a 6.5mm blank and not worry about the specific finish length like you have to do for Carbon 6 and Proof. You can cut these down without any issue.
