I ordered some .358 38 match bullets Tuesday. Amazingly they showed up today. I am impressed with how fast I got them and they look great. Do they resize them after they apply the Hi-Tek coating? I pulled out 20 randomly and mine are all measuring .361. Seems like they weren't sized after the coating? Just curious if anyone else who has ordered some, noticed the same thing. Thanks for the help/replies.
 
Hi-Tek isn't going to add 0.004" to the bullet. More like 0.0005".

According to the directions for Hi-Tek you coat then size.
 
Probably reason for larger size is hoping your gun barrel or cylinder slugs out around .359. Giving extra size sometimes helps accuracy with lead bullets and definitely helps with leading the barrel. The coating would prevent leading anyway. I cast my own and lube some but I do powder coat a lot of them. I cast and size and powder coat and size again. My GP 100 slugs out at .3587. I size mine to .360. My security six I have to size at 359 due to forcing cone size. All are definitely different.
 
From the FAQ of MBC

http://missouribullet.com/faq.php

What is the Hi-Tek coating and how is it applied?
The coating is made in Australia and imported here. We are currently lined to up distribute this coating along with unsized/unlubed bullets so that folks can apply the coating themselves. The coating itself consists of a catalyst which binds a polymeric colorant agent with acetone which is then applied in bulk to raw bullets and baked onto the bullets' surface at nearly 400 degrees. The coating is a polymer (bonded with metal) and forms an extremely tough new surface for the bullet. The application of the coating is repeated for an additional coat. The bullets are then sized normally but not lubricated, as the coating itself acts as bullet lube. Nominal bullet diameter is not affected.
 
I would call Missouri Bullet and ask them why they are .361 vs .358 and get it straight from them...if they say .358 then they should not be that far off
 
I load MB's 38's Hi-Tek coated by the hundreds (mostly the 125 grain RNFP.). My revolvers spits 'em out with narry a glitch. I must admit I don't put the calipers on 'em to double check the size.
As a matter of prudence, I guess I aught to, just to confirm their specs are as advertised.
 
I'm thinking these weren't sized after the coating. I've bought Double Alpha that were this large also. Granted they fit, but weird the FAQ says they are sized after being coated. Unfortunately they are closed till Monday, but I did send them a email asking about the size difference.
 
A buddy got a couple of boxes of 45 Softballs a few years ago that were sized at .454. Call Brad, he will make things right.

That's the reason I have 3 Lee push thru sizing dies ( 0.356/0.357/0.358) and push thru all coated bullets I buy to "qualify/standardize" them.
I buy the biggest diameter sold as standard and re-size to whatever I'm loading, mostly bullets sold as 38 and even size them down to load for 9mm when needed.
If Lee made other sizes like 0.355/0.359/0.360, I'd have them too.

This saves all the "wonder" about what diameter ordered verses diameter received, as most bullet companies have a tolerance.
Even if the MB sends you replacement bullets I doubt they will want the oversized bullets back, so you will need to deal with them.

Buying those sizing dies all at once can be expensive (not really) so buy what you need now, you will have them forever, and find them useful in the future I'm sure.
:D
 
Look at NOE web site. He has push through body with every size bushing you can think of. The bushings are cheap and you can still use the Lee bullet catcher on top to push them into. I think body is around 40.00 and bushings around 6.00. Screws in bottom of press instead of from the top.
 
Yeah I didn't even open the other box, because they have they same date code stamped on the bottom of the box. Waiting to hear what they say first. I dont even have a single stage press to resize them with. I was looking at a Lee push thru sizer though. Figured worse case, I will have to run them out to my Dads house and use his single stage press to resize them. Was hoping someone else had some laying around that they could measure and see if theirs are larger diameter than the stated size.
 
Springback?
Does the plastic coating SB? Can coatings be compressed with a micrometerr ? Just asking. Dont use plastic.

Naked cast bullets, some do , some dont. The harder the alloy, the more SB. About .001" difference at the most.

Found this out the hard way, leading in first inch of 357 mag. Sizing die marked .357" It always produced .3575" bullets for many years. Perfect.
Then was given 80 lbs of pure. Added some limotype. Checked dia as bullets dropped from mold. Larger then needed. Never checked the FINISHED dia. till the leading appeared. Soft alloy doesnt springback.
 
243winxb these are supposed to be .358 with a Brinell of 12. If I really, really try to compress it, I ooo can get a measurement of .360 diameter. That coating is pretty damn hard. I honestly don't know about springback.

Hi-Tek doesn't add much. 0.0005 or so. It's not plastic. It's a stain.

HUH? No, it is not a "stain" If it was a stain it would add nothing to the dimension of the bullet. It is a physical coating which has a dimension. A "stain" would be absorbed in whatever it is applied on.
As is Powder Coating Paint it does add a dimension and bullets need to be resized.

Technically Plastics are a Polymer.

The key difference between polymers and plastics is that plastic is a specific type of polymer. Plastics are comprised of a long chain of polymers, where polymers are composed of smaller, uniform molecules.

It's been described as a stain by the inventor. I've never been able to measure a difference. Nor is it a plastic according to the inventor. There are two parts to Hi-Tek. The coloring agent and the component that is actually what does the work.

You must have "insider" information then.

About our Coatings
Hi-Performance Bullet Coatings is bringinging cast bullets into the 21st century. The Hi-Tek Heat Set Supercoat was developed specifically for commercial bullet casters to provode reloaders with a cast bullet that didn't smoke and gum up reloading dies like a traditional wax lubed bullet. Properly applied the coating molecularly bonds to the lead, encasing the entire projectile in a protective shell that is self-lubricating. This proprietary coating contains no PTFE or Moly.

What this means to you? No messy wax lubes that smoke, gums up your reloading dies or bullet feeders. Since the bullet is totally encapsulated, it also greatly reduces your exposure to lead. Cleaner hands, cleaner guns and cleaner air are all benefits of the Hi-Tek Supercoat.

In use in it's native Australia for over 20 years. We introduced Hi-Tek Supercoat to the U.S. several years ago. It's been an overwhelming success by both commercial and home casters alike.

Nothing more than I've read on the over 500 page thread at castboolits about Hi-Tek.

I get it. Hi-Tek pissed in your Lucky Charms. You've got a hardon against it. So why not just ignore any mention of it?

Geesh get over it. How did you come to any conclusion that I have something against Hi Tek. I use their coated bullets all the time.
Just run out of "brilliant" statements or what?

You seem to be the one with an "issue" You made a statement that it is a "stain" So please clarify that. and show us the fact(s)

Searching the "simple hi-tek coating" thread for stain returns 90 results.

Hi-Tek is a stain. Just like I told you.

Man, you just will not give up, plus you need to resort to being rude and condescending The links you provided show nothing. Might as well have posted a link to the "Internet" or WWW.???

Here it is direct from Donnie Miculek (but what the heck does he know?)

"Dear xyz
The confusion is the use of the word stain is used to describe how thin the coats should be applied (very lightly). Because the coating is thin it looks more like a woodstain than say a coat of latex paint.
I hope this helps.
Donnie"
