Home Forums Hunting & Shooting Hunting Rifles 760 hot brass and split brass

My 760, a .35 Remington, throws the hottest brass I've ever felt and it's a very low pressured round ( 35,000 psi) compared to the .30-1906.

Did you finish 8'th grade? Your reading comprehension indicates not.

My public service was to offer you information about the subject of Physics and the laws of Thermodynamics in particular.

Heat travels from hot to cold.

Steel is a pretty good conductor of heat.

And then there is the science of internal ballistics.

The inside of a cartridge case is subjected to tremendous heat and pressure as the cartridge fires. The brass gets very hot, and is then subsequently cooled by contact with cold barrel steel. Steel with which the cartridge is in contact due to having been fireformed to fit the chamber.

It appears that your Zerk personality is adopting portions of your Slavek personality.

I've had at least half a dozen 760 rifles. I can't remember ever noticing hot brass. I've had one 742 and I was shocked how I couldn't even pick the brass up until it cooled off. I know I never had that with a 760

So did some shooting today. Interesting 165 grain factory corlockt cold. Hand loaded 180 partion/interlock 54.5 grains IMR4350 warm. Same load in bolt, cold. Not a physics tests, because both shooting off bench, and not racking rapidly.

7400 factory ammo, damn that is hot.

Now for something interesting. I bought some starline 30-06. Full length sized it. Would not shoot, dented primers. Tried multiple times could not get the primer to go off. Three rounds dented primers. Fired remington brass after that.

One of the things I don't like about pumps is you have to rack them hard. You can't sneak one in like you can a bolt. I have read to use small base sizing dies. IMO it is a flaw in the gun if you can't shoot ammo out of it.

All my shooting from this rifle has been remington brass, factory loaded or hand loaded


Another interesting thing remington factory brass has cold and silver primers.

You have more important worries than warm brass if your rifle only dented the primers on recent handloads.

Which is why I asked what brass looked like or pics long ago.

If there is a problem the heat could be a symptom. So yes, you should pay attention.
Shoots remington brass just fine.

Starline mics .004 bigger. is that enough? I don't know, isn't much. but pumps can be annoying. I have never used small sizing dies, I wonder id that makes a difference.


Shoots remmington factory and remington brass hand loaded, but dents star line. Yes, I expect some comments.

One theory is, thicker brass, not chambering.

It doesn't need a small base die.

I have loaded for at least 4 of them. Standard full length dies used in all applications.

Only difference is I usually ran a little bit more mild load in a pump.

Starline and Remington brass sized using the same die and die adjustment?

Same primers used in both handload?

Primer seated deeper in Starline brass??

I told myself I was not going to reply to you, cause I can't figure out if you are an idiot or just talking dumb.
Yes same primers, dumb question

Same sizing die, dumb question

Same load works in remington brass, dumb question.

I think I answered my own question, with you again.

Once again.

Primer depth?

What does fired brass look like for about the 4th time??

Actually forget it. Don't answer.

It doesn't matter what someone tells you if it isn't what you want to hear they are the idiot.

Don't forget, you're the one slinging schitt here, others are just trying to help yet you want to criticize them and call them names because they won't tell you what you want to hear.

I could call you a lot of different things but I will take the high road.

Move on, and go shoot a chipmunk with a revolver.

I get tired of repeating myself with you.

I think the moral of this thread is Zerk is a [bleep] idiot..

My theory is the starline is heavier premium brass. I have never used small base dies. But they are made for this it. Talks about them in reloading manuals for pumps. I also wonder about starline being semi new to bottle neck cartidges

One of the things I don't like about pumps is you have to rack it hard into battery. With a bolt, if the bolt is closed you are good.

I retired this gun for a few years, the rattle drove me nuts too. Replaced the oring. I like the stock on this rifle, it feels good. I was going to cut it down to 20". But now with Remington, I don't know. Though there are a ton of these out there. Which makes me laugh when people pay dumb money for them

I email starline, to see if they share an opinion.

I have considered in past getting small base die, so this racked nicer. But it works as is. If I did I would probably settle on brand of brass, and just stay with it, to make sorting easier. I have a ton of remington.

If you want help/ideas about an issue with brass, why not post photos so people can see what's going on?

Do you want a picture of a brand new starline?
The forum software is old here, I would have to send it to my computer resize it, and then post. It won't accept pics from a phone. I posted that a week ago.

I also feel like it is a waste of time with some here.

Reloading manuals talk about small base sizing dies. And some act like it is made up because they never did it. I never did it either, until I bought starline. I suspect it is a premium thicker brass. I would not be surprised if I bought other premium brass I encountered this too.

Then what's the issue??

Exactly what can one learn about a firearm from unfired brass?

Yet you call me an idiot?
