Re: .243 win and h4350 questions!
I have a question as well just piggy backing on this question.
Barrel 26" Mcgowen Barrel
I am running 41.5gr H4350
CCI BR2 primers
400Ft ASL of evelvation
29.62 HG pressure
i should be getting 2900+ FPS according to a reloading guide and several other sources. But my DOPE says other wise , i was shooting this past weekend ZEROed the rifle with a 300yard zero. my program stated that i need 8MOA give or take to get out to 600yard. Atmosphere conditions taken into account.Now real life i was more like 11MOA to get from 300 to 600. i dont know what is the issue with the load not pushing 2900FPS. ANyone have thoughts at all on this?
