I spend more time on cast bullet specific forums, that's my thing. I shoot cb's in everything. Fairly often some one will ask 'what's the limit?' for 45-70 loads in a Handi. Usually it's the result of seeing the different load levels published in the loading manuals. There's always a standard reply, from some one, pointing out the gun will stand more than you can. I agree, been there, done that. Now I look for lighter and lighter loads for my H&R 45-70. More fun, less pain. I got some Trail Boss and Ranch Dog 350s to mess with. But, I'm wondering what others have done as far as pushing the limit. What's the heaviest load you've tried? I'm just curious, not likely to go there again myself. I'm definitely not advocating heavy loads or exceeding published maximums, just wondering.
