That was the problem,when I bought the rifle there wasn't any bullet choice except what was being sold at the same shop I got the gun,I remember they were winchester ammo in silver cases with black coated bullets and red hard nylon tips.not sure what the weight on them were ,but no other choice really as they were a new cal and no selection.I shot bears up close and deer 100 yards plus,too much damage for me.
I do remember they were big game rounds ,I didn't expect that kind of damage.I have used 30-06 with light and heavy bullets for a long time ,45/70 even longer,and never made a mess out of an animal like that little .243 wssm.those that are saying it was bullet choice ,well there certainly wasn't any selection of ammo back then on te shelves,and I don't know any local shops that even carry the wssm ammo.ive never seen it in years .
I still see quite a good selection for .300 wsm.
