I would like to shoot some cast bullets in a 45-70 but its ported will it work ? :?

Gas Cutting

The ports allow for some serious gas cutting on the plain base bullets and will destroy your accuracy.

P.J. thegas checked work just fine, but.....

...you need to check your ported area for debris, and you will get whiteish/blue streaks outside of the vents...it wipes off easily though, but all the same ....I just didnt like it...and stopped doing it. I dont know about un-checked bullets.
