Are Hi Tech or powder coated bullets safe to shoot in polygonal rifled barrels?
Want to do a 8 inch 300 BO but keep running into Polygonal rifling in barrels that aren't $250+...Missouri Cast Bullet Company is showing Hi Tech coated 245gn 308 bullets available at $40/250. This an acceptable price point to me to make 300 BO sub's but don't know if the coating will be GTG with any rifling type. |
|
Yes, they're Glockable as are dry-lubed cast bullets from other companies. Load to cast bullet specs.
Hi-Tek is supposedly a 2nd generation dry lube. When Precision bullets first introduced their dry-lubed bullets back in the 90's I literally shot tens of thousands of them through my Glocks with no issues. |
|
Other companies? Sorry maybe google fun is weak, could you share?
|
|
All I've purchased recently are coated bullets, mostly "blue bullets" for use in my Glocks. They work very well.
|
|
I know Black Bullets Int. are now using the hi-tek coating, as are Bayou Bullets (local guys called LNL bullets use the bayou method).
No idea on .300 BO offerings, but the pistol calibers using the hi-tek coating are GTG out of poly-rifled barrels. I use coated bullets for all my pistol competition ammo, and love them. A bit smokier than plated or FMJ, but very clean on the bore, even after hundreds to over a thousand rounds, and the lower price means more trigger time. |

Am looking at the #309245BLK .309 Diameter 245 Grain RNFP for use in an AR15 pistol with a 7.5 barrel in .300 BLK. Got a few questions: Do you have any recommended or starting loads for these in .300 BLK? Would these bullets lead up a suppressor if I get one? Thank you for your time, |

Any word on whether these will lead up a sealed can? View Quote I don't have a supressor but I think I can answer your question. I have recovered many of the coated bullets and they retain nearly 100% of the coating even after pent rating through several inches of wood. I don't think they would cause any problems with a supressor. |

I just ran some Ares polymer coated projectiles through my G17 and G35.
The 9mm, 147gr polymer were 50-80 fps faster than 147gr plated with identical load and OAL in a G17. I have 180gr polymer .40sw but I have yet to test them against 180gr plated. With about 100rds of polymer coated through each gun I have not noticed any build up in the barrel. |

They are expensive but you can get them from the Canadian dealer out of Montreal. I only bought 250 each of the calibers I wanted to test but they had 1000 and 2000 rd boxes for sale.

Upper receiver built and test fired with 60 Remington 220gn subsonic rounds last weekend. I ordered 750 of the coated 245gn from Missouri Bullet Company and 250 of their 165gn coated bullets to play with for a heavier super sonic round. I will be making another 100 or so 208gn Amax rounds tonight and shoot them this weekend. I will post pictures of the baffels before and after I clean it, hope to have the cast bullets by next week. |

How is the accuracy of the Hi Tech or powder coated bullets out of the Glock polygon barrels?
|
|
I can get about 4" at 25 yards, I think the limiting factor is still the shooter at that point.
Better than plated, about the same if not a bit better than jacketed for me. |
|
this is on my winter to do list, picked up a 144 gr mold to try with HiTech coating if everything works out , plan on having a set of molds cut for the Magma Bullet Master
|
|
Most reports - at least of the non coated versions of these bullets - state that these bullets are horribly inaccurate. I'd certainly like to see some information to the contrary, but until then I'll stick to 208 hornady bthp blems for sub plinkers.

I'll be honest, got to loading some of these up, and the coating is pretty spotty. I'll get some pics up later, but on the bullets I've got, there's a good bit of exposed lead. As probably expected, you MUST bell out the case mouth to get these to seat without carving off the coating (so you'll need a die to do that belling). Just had the chance to pop off a few I loaded up this evening, around 9.0 grains of IMR 4227, and seated like a SWC (about a fingernail's thickness from the case mouth to the diameter change on the bullet). This load functioned fine in my 10.5" pistol with suppressor, didn't get a chance to put it through the carbine. Will report on velocity and accuracy when I get the chance.

I've shot coated bullets for years, but always in pistols. How fast can you expect to push these newer coated bullets in a rifle before there's an expected issue?

I just seated until there was about a fingernail thickness of distance from the case mouth the last sharp diameter step before the ogive. Fed fine. |

Did you use an M die to open the case mouth a little?
Would appreciate the measurement, still waiting on my delivery. Will get pictures up tonight of the Mystic baffles after all FMJ shots. |

Did some shooting this weekend with the MBC 245gn.
Tula KVB223 primer 10.7gn of IMR 4198 PMC resized brass (checked neck thickness all showed at 0.11) Loaded to 2.105 Trimmed to length with Giraud trimmer Belled case mouth with Lee expander Medium crimp with Lee FCD Rounds stabilized and made nice round holes, no chronograph but were going super sonic through the Mystic once stabilization was verified. 10.6gn of IMR 4198 kept the round subsonic. Function was not 100% reliable, would get inconsistent FTF, round would start up the ramp but would get caught on the magazine feed lips, not sure what mess with on that one. I fired 54 rounds of the 245gn MBC coated rounds, during clean up I did note some lead build up on the muzzle right where the rifling is. I will check the Mystic tonight to see how it faired. |

Using Precision Bullets' 124gr RN and VV N320 (can't remember the load) I used to put FBI "Q" targets out at 15 yards and put 100 or so rounds through them. left a nice hole about 4-5" in diameter COM. |
|
Even with the Lee expander I am wondering if I need a larger neck expander. Seating these bullets isn't smooth and some are visible not getting seated straight in neck. Might pull a few after seating and see what the before and after sizes are, curious if the neck is swaging the bullets down a bit.

Thanks for the pictures Rocket. I am planning on loading up some more rounds tonight after work. I really want to get a good sample size before I post pictures of the baffles, going to shoot 250 rounds before posting pictures of the baffles. These are all being loaded single stage so making the rounds is taking longer to complete.
I did get a couple of rounds where the coating didn't coat in the lube grooves, this may account for the lead that was noticed on the crown. |
|
|
Tried oil, brass brush, exacto knives but that was about as good as it got.
The baffles cleaned up with oil and a brush, didn't come out perfect but the big junks came off. Was going to keep shooting without cleaning but after the effort to get the stack out went ahead and cleaned it. So far that is all IMR 4198, haven't tried any other powder. |

|
Yea I bought a crapload thinking they would be great for suppressed loads. I tested 12 rounds of .45 acp I loaded yesterday. While not quite as bad as uncoated lead I will be selling them all. They are still dirty and I can see lead residue on my glock 21 mag from only those 12 rounds.
|
|
thanks for the pics and report, can't say I'm surprised by the result
|
|
The baffle build up was all carbon, nothing shiny in them when I cleaned it.
Still thinking about why, what appears to be lead, is only in the blast area. There was a lot of carbon in the first couple of baffles but no shiny build up. Look at the picture where the I beam support is. Wonder if I shot a few super sonics after sub's would help burn out any residue left behind. |
|
I contacted MBC about this to see if it might be a bad batch or something, and in the event that it's something that needs more development, offered to run some testing for them (for free) to see if we can develop a way to make them work well. I will post in here, and probably make a new thread as well, if they respond.
|
|
Went through my open box of 250, there are some where the coating didn't get into the lube grooves and left bare lead. Even the ones that are coated aren't coated evenly.
|
|
Mine are coated fairly evenly. They are shaped like regular bullets with no grooves. I will clean my glock really well then try again but I'm pretty sure they are just way dirtier than fmj.
