458 Lott Hornady DGX / DGS
I just recently started reloading 458 Lott and I am using Hornady DGX 500 gr , 350 gr interlock FP. I tried a few of their recommended loads and was not to impressed with what I got compared to the factory stuff they sell.
When surfing the net and in the cartridges of the world reloading book along with Hog tech service , Jack Lott himself all indicate 500 gr bullet with 75-85 max gr of IMR 4320. Hornady for some reason recommends a Max of 77 gr IMR 4320 with DGX / DGS ??? with real poor velocity ratings as expected.
Has anyone ever shot the DGX / DGS rounds with IMR 4320 before and if so how did it work pressure wise ?
When I asked Hornady about this they just said that they used a Ruger 1-10 twist 24" and that's all they could get out of 4320 in that rifle. I also noticed all their recommended loads are are lower velocity then what they sell pre made. They won't give up their secrets either I tried already. They use 77 gr of something they won't share ?
Can the 500 gr hornady rounds be so different then others that IMR 4320 at 85gr is not an option because of their reload data or did they just have a bad shooting day at Hornady ?
