I would be very careful if I were you.Wild West Guns even tried and made the 500 Smith in a beefed up leveraction and it didn't hold up to the pressures....Everyone try's but until just recently,none have held up to the pressure....

Then I could say no one thought you could make a 454 Casull in a leveraction,but they did at 65,000 PSI/SAAMI.But others failed miserably.

I would be real hesitant until it is tried and proven and just not another idea in a long line of them.

The data for a 500 Smith in a 22" barrel does not not meet the ballistics of a 45-70/.450 Marlin..Surprised me also.

22' Barrel data for the 500 Smith!

Just my opinion.....
