I find the Noslers to be difficult to load. They seem to have changed plastic sabot manufacturers also. This time they appear to be MMP... just like T/C recently did by switching to Hornady. My most recent batch from Nosler featured tan 44/50s that were a bear to load. I threw the remaining 46 or-so leftover from the package away. I still have the black 45/50s. They are real thin & long petaled. I think they are MMP HPH-24s. However, they don't slide easy like the Harvesters. Both of these appear to be too soft of a plastic material that grabs the bore walls instead of slides. Stay with the Harvesters for tight bores... otherwise buy the MMP HPH-12s for normal/oversize bores.

I'm getting more n' more into shooting bulk Speer Gold Dot bullets. They come in 180, 200, 210, 240 and 270 grain for 50/54 caliber. I prefer the soft points . but I also own the hollows. They are just as accurate as the Hornadys. Eventually, I'm going to try Nosler bullets too. I see they come in .429 and .451 bulk too.
