A few points to clarify.
1. Why this action?
The rolling block action is an inherently sturdy and accurate action, in most cases making it even more accurate and sturdy than a bolt action rifle. The only drawback is that it sacrifices ammo capacity for excellent accuracy and durability.
2. Why so many cartridges?
IRL sporting rifles come in a dizzying array of cartridges. This is because of shooter preferences (regarding recoil, how they like their bullet trajectories, etc.) This rifle comes in a small caliber, a medium magnum cartridge, and a heavy cartridge to satisfy three different groups of shooters: Shooters who desire a small cartridge to have fun with that's still flat-shooting, Shooters who desire a magnum cartridge for long-range shooting, and Shooters who desire a heavy cartridge for the novelty of it and for the utter power behind it.
3. Why different DR values for each caliber?
I based the DR values of each cartridge on what type of game each cartridge is suitable for. The smaller caliber has a DR of 2 because of the fact that it is considered a small-sized round for varmint hunting (coyotes, squirrels, small game, etc.) The medium caliber has a DR of 3 because it is used to take larger game (deer, pigs, two-legged animals, etc.) The heaviest caliber has a DR of 4 because it can be used to take larger game.
4. What are "wildcat" cartridges?
Wildcat cartridges are pretty much cartridges that can be considered "non-standard", that is, the popular .30-06 (used in the M1 Garand, etc) is a standard cartridge you can buy. A wildcat would be taking the head of a Mauser 98 bullet (8mm) and putting it in the case of the .30-06 round used in the M1 Garand. This can be done in the backyard and sheds of several gun owners with reloading equipment.
