Ive been reloading for a little bit now, far from expert but powder selection has always kind of confused me. Im looking on HODGON's web page http://data.hodgdon.com/cartridge_load.asp for a good load for 30-06 shooting 190gr. Ive been using IMR4350 and no complaints with it.
Their data shows a 190gr BTSP going 2647fps with max load of 54.5gr of IMR4350. Also lists 58,500 psi as the pressure associated with that.
The same table shows 190gr BTSP going 2608fps with 46.5gr of Varget with a 46,700 CUP pressure accosicated with that.
My question, if Varget is a faster burning powder than IMR4350 and not really recommended for 190gr especially in 30-06, whats the deal with the pressure difference. I understand PSI and CUP dont exactly match up but a 14,000 pressure difference!!! And your getting almost same velocity. So whats the deal, why should I not use a faster burning powder like Varget. It seems the better deal to me, less pressure, less powder, almost same speed. Help me understand im just not seeing it.
