Bravos are good chassis. You said you single load which indicates bench or f class type shooting
the bravo is not heavy, and the polymer forend has a bit of flex in it. Under the polymer is an aluminum backbone, but the polymer inself presents a little bit of flex
My krg X-ray custom gun is a consistent 1/2” to 3/4” 308 off a bipod with a rear bag. I think with a bit more rigidity in the forend I can get that 1/2” to be more consistent and reduce the number of those 3/4 groups
depending on accuracy demands, barrel, and front and rear rests this may or may not matter to you. I’m going to upgrade my X-ray with an aluminum forend that should reduce the flex significantly
