I bought a chronograph fairly recently and it's a good thing because it gives me more reason to go through the gun safe and fire some rifles that had become otherwise dormant.

I put some of my 270gn handloads through my 375H&H CZ550 and recorded the results thinking nothing of it - average of 2858ft/sec with a SD (10 shots) of 13ft/sec. I've since found out that that is actually a fairly "healthy" velocity. Loads are far from hot (primers look good, cases extract easily, brass lasts a long time etc). I guess this must me due to the longish barrel.

Anyone else have chrono results for comparison?
