[QUOTE="jdyoung, post: 1997802, member: 113391"] According to the Hornady manual you referenced. [U]In that Manual, u[/U]sing Hornady 150 gr SSTs at a [COLOR=rgb(184, 49, 47)][U]col of 3.210” [/U][/COLOR]as shown over 61.6 gr H4350 will only produce 2950 fps, and according to QuickLOAD, it is a [U]13.5% compressed load[/U] . (QuickLOAD also shows 3110 fps at that length with pressure at [COLOR=rgb(184, 49, 47)]68,191 psi[/COLOR]). [U]In that Manual[/U], reducing that load to 58.1 gr of H4350 to give a velocity in the range of 2800 fps [U]is still a 7.0% compressed load[/U] at 55,695 psi (ref QuickLOAD which shows a higher velocity of 2930 fps) [U]At a 30-06 standard col of 3.340”[/U] with that H4350 charge of 61.6 gr, [U]it is a 9.8% compressed load[/U] (ref QuickLOAD which shows 3046 fps at that length ,pressure is[COLOR=rgb(184, 49, 47)] 61,988 psi[/COLOR]) [U]At a 30-06 standard col of 3.340"[/U] with a charge of 58.1 gr of H4350 it is a [U]2.9% compressed load[/U] at 2871 fps and 51120 psi. More acceptable but still a compressed load. Increasing the col can lessen the compression and pressure but if the bullets have a cannelure, you probably won't be able to crimp the case mouth into the cannelure groove. No offense, but to me, compressed charges are not worth the risk ! I know seasons are here and supplies are short in components and loaded ammo , but I certainly would go for what I consider a safer route when it involves a family member or friend. [/QUOTE]
