I would encourage you strongly to use and enjoy your gun. I would also encourage you to go as lightly as you can on modifications and loads. I would shoot reduced recoil .30-30 loads if you can find them. I have shot my Hollenbeck a in 32-40 and 30-30 very casually. However in 25-35 I spent A LOT of effort working up a load and figuring it out. I found the gun to be VERY sensitive to presssure and what I thought were very light starting loads were too much for it in the long run.
I shoot it. I love it. I would never discourage anyone from using one but I hesitate to plunk factory loads in it. Even though we all think .30-30 is a light round.
