I have Remington 760, 81 or 83 30-06. The brass has been coming out very hot. I don't remember it doing that before. Imr4350 54.5,. With partions. Remington brass with wlr. I don't recall the hot brass in past
And then last time,and this may be indication, it split 2 brass out of 25. Brass had been sized years ago,and tumbled after. Someone though cases seemed like they had lube split on neck length of body.brass was only fired twice.
I did remove barrel in 2016 to replace oring. Shot maybe 200 times since
I picked up box factory ammo this weekend, and when I get home will see if the brass is hot . If not hot, I am going to clean my brass to see if lube is issue
I also stuck a mop in barrel from chamber. I do clean barrel a lot,but not chamber.
I've gotten this rifle to 1" with cold shots.
Opinions on hot brass? Thanks

Fired brass is very hot from everything 22lr and up.
When I die I hope I don't start voting democrat.

Bolts are not hot. 300 win mag, same load in 30-06, cold. Maybe doing lots of shooting to heat barrel it is possible.
I think semi autos may be hot due to gas. But not a bolt.

Zerk, my experience is that brass is hot coming out of the chamber. Just get a few down your neck. Your 4350 load is very moderate and shouldn’t cause case neck splitting. I regularly load 56.5 gr for my 30-06 and it’s still below max. I’m thinking it’s brittle brass. Just a bad batch. I had a box of that some years ago and threw it away. Remember that you’ve set off a (hopefully) controlled explosion in that case - that means a lot of heat. If the chamber (and I’d be surprised if your chamber damaged) is OK then just use a different batch of brass.

Go shoot a round in backyard from a bolt. I have been doing lots of shooting lately. 300 win mag and 30-06 yesterday. Brass is not hot from a bolt.
I am not sure if pump is exact same as bolt if there is a way for gas to blow back. I don't have pump with me.

What is your experience with bullet impact on split case? I am getting ready for hunt and concerned about shot placement if brass cracks

I have never had a bolt operated rifle through brass down my neck,that I recall. Again I suspect the difference is gas operated guns.

Years ago I had a BAR in 243. The ejected brass was always too hot to pick up as soon as it was ejected. Never figured out why. A bolt doesn’t eject hot brass. Why the little Browning did, I never figured out.

Why the little Browning did, I never figured out. It's a gas gun, brass will be hot. BAR, Remington or whatever other semis are all the same. If you could operate a bolt gun extremely fast you would get some pretty warm brass. Not as hot as brass from an auto but pretty warm. With a bolt you're probably 2-3 seconds or more after firing before you spit that brass out in your hand, it's already cooled a bunch. No surprise brass heats up as it just had a hell of an explosion go off inside of it.

One of shots was low. Not sure about other.
I ordered some starline brass. I got tons of Remington. But I got trip coming up and I want this as back up
I hope sleeping dog ammo is legit. It came up on ammo seek.
Back to pump does some of the gas blow open slide? Some people saw their slide opens. I always wondered if that is some kind of wear. Of course I don't think about it when shooting

If they open easy a lot of times they come part way open on firing. At least 1 of mine was that way.

Back to pump does some of the gas blow open slide? Some people saw their slide opens. I always wondered if that is some kind of wear. Of course I don't think about it when shooting On a 760 it's not gas, it's mechanical and it's only because you're shooting off the bench. Upon firing it disengages your action lock. It's all happening in milliseconds and it would be like after firing if your bolt was all the way up on a bolt gun ready to be pulled back. Difference is the forearm is being utilized as your bolt handle and it is setting on a front support. The rifle recoils back into your shoulder then front again pushing the pump (bolt) slightly open, or sometimes very open. Very hot brass is not uncommon as it had no chance to cool in the chamber. Shoot it normal and not off the bench and you will notice the brass isn't near as hot, or not at all, because your action will stay closed immediately after firing.

Again, do pump's brass get hot or not? Bolts do not I was shooting different times with hot brass. Same brass in bolt, not hot or splitting.
I bolt I shot 75 or so, no splitting. I have ejected brass fast and slow on bolts, it is not hot. With pump it is not warm, it is hot.
I have my doubts it has anything to do with how long in chamber. The rifle is cold. Slow shooting.
Maybe slide is opening and allowing gas to heat brass. Odd I never thought about this before. It is very hot.

With a bolt action the fired case stays in the chamber long enough for the chamber/barrel to act as a heat sink, drawing a lot of the heat from the case.

direct impingement gas gun equals hot piston driven gas gun equals slightly cooler bolt gun equals nice and cool...
