Did roughly the same thing on a ferrell hog hunt with factory 300 grain XTP/HP 44 mags out of my Marlin 1894. 30 yard shot the pig fell like something knocked its legs out from underneath it. this was big pig too it weighed in at 261 lbs.

I never tried the Light Magnum stuff ,but I use the Custom in my 7 rem mag and 22-250 and get ragged one hole groups when I do my part.
I also agee with a previous post , I also like the Federal Premium. The Hornady 139gr. and Federal TBBC 140 gr. shot to the exact same point in my 7 rem mag and give the same one hole performance.

I was using the Hornady's out of my .243 exclusively. I dropped a 200 pound boar at 220 yds with it. I mean dropped it, I could hear his head hit the ground. Complete pass through on the neck, same with deer, I put some big 'ol holes through deer with them also.
Past two years I have been using federals with the sierra game kings, not much difference if any, cheaper and easier to find.
but to answer your question, Hornady makes fine ammo. I would highly reccomend them.
