Polymer coated bullets

[capo602002]

I recently decided to give polymer coated lead bullets a try in 40 S&W.
Bullets are readily available from several different manufacturers.
Finding load data was another story. BUT - after a bunch of searching I ended up on Federals web site accessing their reload data. Never knew Federal provided load date. They provide load data for their Syntech bullets which are polymer coated lead in several different powders. For those interested here is a link to their site.

Many of us have used Powder/polymer coated with good results. I really liked them in .38 SPL, and have a bunch to try in 9mm, but luckily I don't own a Glock, so no worries there...

Here's the Egglestons Load Data page.

Instead of scouring the internet looking for polymer coated bullet specific load data, why not just use lead load data and work up from there?

I was looking for load data that used powders I already had on hand. Makes things a little more difficult. Unfortunately the Eggleston data did not list the bullet (160 gr from Eggleston) or any of the powders I had on hand. The Federal site did though. Same with most of lead load data I had.

Yeah, that is what I've been doing. Seems to work well, as they are just coated cast. Mine are Missouri bullets. .45 Colt, .357(158 and 180) and 30-30 in 165gr loads. Seems also to clean up(bore) pretty easy.

I use Brazos coated for .357 (158 gr) and with lead load data. They work great and clean. I tried coated, both Brazos and ACME in 9mm, 115 gr. They work great in my M&P9, they lead the crap out my CZ barrel. Went to FMJ for the CZ and the FMJ work just fine.

Using MBC's Hi-Tek coated 165 RNFPs in .30-30 I noticed the lead load data with H4895 was leaving a LOT of unburned powder in the bore (typical for not enough pressure / too low charge), have you seen similar? I was going to keep moving up from 21 grains into jacketed load data territory until I see evidence of coating failure (leading I would assume).
