So how close is the .400H&H to the .400 Pondoro discussed in the A square manual? The Pondoro has a .409" bore and propells a 400grs bullet out of a 26" barrel at about 2350 with about 53,000 CUP pressure. The .375 H&H is about 53,000 CUP with a 300 grs bullet. Could you shoot .410 pistol bullets out of the .400 H&H?
