Rhys95, welcome to the board. You have a very nice gun by a well known maker and at a very favorable price. There are two factors you need to control in selecting ammo. The first is pressure and the second is recoil. Pressure affects the metal parts and joints between parts. Recoil affects the wood.
Pressure is controlled by shooting ONLY loads, factory or reload, of KNOWN pressure. IN the USA, we are able to buy suitable loads from RST. Equally, we are able to make reloads easily and at about 50-75% of the cost of factory.
Recoil is a function of ejecta weight and ejecta velocity squared. If you will confine your shooting to 7/8 oz and 1 oz loads at about 1200 fps and 1 1/8 oz loads to less than 1150 fps, you should be fine.
Generally, loads below 7000 psi should be fine. Will you buy or reload? The 3 1/4 ton per square inch proof for 2 3/4" chambers is nice. It proves the gun is reasonably strong. The chance of it "blowing up" is remote. However, I'd not recommend a steady diet of CIP shells.
Questions?
