I agree with both Skyline, and Ray especially where cartridges used for large & somtimes dangerous game animals. The selection of good quality bullets is one of the reasons for this, but not the only one.
As Ray says I can load better ammo than the factories, and it will always feed through all my rifles, and chamber easily in my double rifles. The bullets will do what they are supposed to do. The saveings in cost are real when you start to use any of the Nitro Express cartridges, in both money spent, and allowing you to shoot more becoming at one with a rifle that may be needed without time to think, or even aim.
In the case of double rifles, very few will shoot to regulation properly with factory ammo, and handloads will make your double rifle shoot properly shot after shot. Anyone who takes to shooting a double rifle it's almost a sin to not load your own ammo, and if you want to get the best from a double rifle you will handload all your ammo, not to mention cost, $17 per shot for the 470NE for factory from federal.
Gentlemen there is a difference between a re-load, and a hand-load. Re-loads are for practice stump shooting, and to save money learning how to shoot your double rifle or big bore bolt rifle instinctively. HAND-LOADS are what you use to save your life, or the lives of others in your hunting party.
What I mean by all this is, Hand-loads to be used hunting for the bite-backs is loaded by hand, after properly matching the brass by weight, sizeing, and trimming, seated with bullets that are the best you can get, in NEW brass, useing fresh primers, all loaded with the same lot# powder. When you finish a batch of those loads you can weigh every cartridge, and they will all weigh the same or very close to it, and all will feed through your bolt rifle, from a full magazine, or chamber in either barrel of your double in a "DROP-IN" smoothness.
Like Ray and Sky, I have been hand-loading for all my rifles since the early 1950s for all my rifles, except rimfires,the only place I use factory is with the rimfires, shotguns and simi-auto pistol ammo. All hunting ammo is Hand-loaded, very carefully, and the recipes are all for individual rifles, so as to get the best load I can for any rifle I own.
