Round nose cast bullet for 44 Mag?

[mtgrs737]

Hi all, I will shortly be loading for a 92 in 44 mag. My question is: is it safe to load a 240 gr. Lee round nose cast bullet for use in the 92 tubular magazine? I do load and shoot them in a handgun but would not want to not be thinking and load some of those round nose bullets in the 92 for fear of setting off rounds in the magazine tube from recoil forces. So, anyone have any experience with round nose cast?

Thanks!
