there is no way to answer that. If I tell you something

like our 30 GNR is safe and you run it way past max and blow the gun up or run the wrong powder in there and blow it up, then I am at fault. The person shooting the G-2 or loading for the G-2 has to decide for himself what is safe. I would recommend never shooting a high pressure round like the 454 in there nor would I recommend any of the 50 caliber rounds as the chamber walls are very thin with that cartridge. But that statement can come back and bite me in the ass as I have chambered a lot of Contenders in 50-70. Some of my personal cartridges are probably not good ideas to shoot in a G-2, like the 476 GNR, based on the 50 Alaskan, but on the same note my 416 GNR and 450 GNR, bases on the 50 Alaskan work fine in the Contender and they were actually developed for the Contender as there were no Encores or G-2 around in 1990. All of my cartridges based on the 405 case are fairly high pressure cartridges but they were all developed in the Contender years before the Encore. So there are no cartridges that are mine that I would say absolutely don't shoot in the G-2. And I would be a hypocrite if I did as I have some of my personal cartridges chambered in my G-2s that I would never chamber for a customer as I have control over the loads in my barrels.

In factory ammo, for sure stay away from any of the belted magnums or even any of the non belted magnums like the 416 Rigby or Ultra Magnums or WSMs. TC chambers some of these in the Encore but for sure not the G-2.

So if you are not sure of the safety of a cartridge in your G-2, don't do it. Look at TC's list of cartridges they chamber in the G-2 and if you have questions ask on here. Somebody will know the answer.
