I am ordering a 110 BA next week with plans to do the following:

30" Hart 416R Stainless Fluted .875 (est.) barrel chambered in .338 Edge (.338 -.300 RUM).
Does anyone know if the 110 BA bolthead is removeable like the standard 110 bolts, and if it is necessary going from the .338 Lapua to the .338 Edge (.300 RUM case necked up to .338)

The goal is to shoot .338 at 1000+ meters cheaper than the Lapua.

Additionally, how many times are the .338 Lapua shooters reloading their cases (like the Lapua or equivolent)?

Does anyone see any other issues I should be factoring?
