Just a little more info;
When I'm getting ready for the hunt, I fire 2-3 primers through my rifle before I load it. This removes any oil or moisture. Then I load it (all except the primer). In my state, the rifle isn't considered loaded until the primer is installed. I have a small belt pack that I use. It holds 3 wads, 3 bullets, the triple Quick Load Tubes with the desired amount of powder & 3 primers and a ball starter. As far as the rifle goes, that's all you need in the field. Then I load my other gear - knife, drag rope, yada, yada, yada. Then the Range Box with all the other stuff goes in the truck. Most likely, 4 shots is more than enough for one day afield. If it isn't, it's time to go back to the truck for a break. Eat a sandwich, have a Coke, clean your rifle, restock the fanny pack and put your head back on straight.

By the way, if you hunt in areas that are cold, remove the primer before you put the rifle in the truck, and then leave it in the truck over-night. If you take it in the house at night, where it is warm, moisture will collect through the primer hole, into the powder and foul your load. Just saying. It happened to my son.
About rifle barrel twist; There are always exceptions, but it's been my experience:
The Old Long Rifles generally had a 1:66" twist best suited for Patch & Round Balls.
Newer Side Lock Rifles generally have a 1:48" twist, again, best suited for Patch & Round Ball. Might shoot well with a Conical Bullet???
Some later models have a 1:38" twist. They shoot a Patch & Round Ball very well. They also like Conical Bullets. They will, sometimes, shoot a Sabot well if you select a bullet of 200 gr. or less. (that is my experience)
Our CVA Optima and most newer rifles have a 1:28" twist and generally shoot best with Sabots and a bullet of 240 gr. or heavier. Like 240 gr., 250 gr., 295 gr., or 300 gr. (the heavier bullets maintains better energy at longer ranges)
Just buy a variety in smaller packs and see what works best. Once you find what it likes, you can buy the wads, (50/pack) and the bullets (100/pack) and save on the cost. Midway USA or Cabela's should have them. The wads come in different colors depending on whether you choice a .429" (44 cal. - green) bullet of a .452" (45 cal. - black) bullet. I've seen no difference in accuracy based on bullet diameter but weight really does matter. You might select one diameter over another based on bullet design and impact performance.
I hope this helps.
