If you are talking about tube inserts like those used for skeet, I don't think the mfgs will recommend shooting turkey loads through them. The 28 ga tubes are designed for 3/4 oz target loads and the .410 for 1/2 oz loads. Turkey loads could easily be twice that heavy. By all means, contact the mfg and ask them, but I personally think it is a bad idea. I have heard of tube sets cracking from shooting target loads (albeit from a lot more shooting than you will ever do with turkey loads).
