Gey yourself some good current reloading data for the round and see how much you can download it. A lighter bullet at less velocity can help reduce recoil. Start with the lowest power lightest bullet loads in your data and check for accuracy.
You can fiddle with the load from there. Obviously you'll want full power and a heavier bullet for hunting but you have a few months yet before you have to use those again.

For myself I would want to have that chamber issue solved before I took that carbine into the field. As a point of information there are no drill scope mounts available for that model receiver. Considering how notoriously bad those sights are it may be something to consider for use as a hunting rifle. You can try thecountryshed.com they sell many milsurp no drill mounts. Many are the scout scope type.
