TP9 Polygonal barrel: Plated or only FMJ?

[tkarl]

Thinking of getting either a CT9 or a TP9. With the TP9's polygonal barrel, I think I know I cannot shoot lead bullets, and that I need to shoot FMJ. Well, how about copper plated bullets? Like these: http://www.midwayusa.com/product/1050308877/rainier-leadsafe-bullets-9mm-355-diameter-124-grain-plated-round-nose
Can I shoot these plated bullets in the polygonal barrel without lead fouling?

[CJB]

They may foul.

I've shot tons of lead through my PM45 (poly rifling), and it never fouled much at all, and cleaned easily. YMMV as 45 bullets go a wee bit slower than 9mm bullets do.

I use them and they work great, just don't load for over 1500 fps is what I think they recommend on their site. Another great bullet is the one produced by Berrys manufacturing. https://www.berrysmfg.com/

According to Lee's reloading handbook, there are only three possible loads that go just slightly over 1500fps -- and those are for "90gr XTP" bullets -- I'm not even sure what those are! Just to make sure, you were referring to plated bullets and not a lead compund?

You do have the option of using Hi-Tek coated bullets that sooo many bullet companies are now selling and they runthey work well in polygonal rifling . I have run a few thousand coated bullets from Buyou and Missouri bullets thru both my regular and polygonal kahr 's and my sigs polygonal barrels .

Most times the price is lower than traditional lubed lead and eg copper coated .

I've got some of those bullets too! So glad you mentioned this because I never thought they would work in polygonal rifling! The bullets I have are from a local guy: http://www.snscasting.com/bullet-information/. The website lists the same velocity limits as for the copper plated bullets. Wow, more options! Price listing is $62/1000 9mm 115gr. RN bullets. Not sure what shipping would be -- I got mine at a local gun shop.

You will want to get a lyman M die for neck expansion . It gives that little extra that lead and coated bullets need over a normal expansion die .



If you paid $62 a 1000 locally that's a sns retail price so good buy for 115gr
