retreeverKnowing how to shoot a big rifle and it fits you, you can see rapid accurate firing is possible and doable with practice. Great shooting.

shootawayThanks Mike.I adjusted the windage to the right and tightened down the sight screw with loctite.Ishot a few rds offhand today and here is the target.The rifle does not shoot the 405gr bullets well.The best groups off the bench,at 50 yds were three and four inches large.I am going to see how well it does with 500 grainers.[URL=

Either this was a shotgun with buckshot, or really bad shooting...oh wait, never mind

Once a new bore gets really hot,over and over again,it turns to shit in no time.A couple of weeks ago I put 1000rds down the bore in a single week.Four days at the range about a half hour each time.This and a bullet or load that was never accurate from day one.

Tyler KempBoy I bet you nearly shot the rifling out of that barrel after 1000 whole rounds...
Love shooting precision and long range. Big bores too!
Recent college grad, started a company called MK Machining where I'm developing a bullpup rifle chassis system.

It's not that the rifling is shot out.The rifling looks like new.It's just that when it gets so hot that I see the streaks of acraglass I put on each side of my rear sight start to boil ,shit happens.

lets see:
1000 rds in 4 days /half hour a day.
thats 250 rds per trip @ half hour shooting
thats 8.333 rds a minute for the whole 30 min or aprox 1 rd every 14 seconds for 30 mins.

you are full of it

a.tinkererShootaway-
Will you please tell me what you're using as bedding compound - especially the stuff you said was melting/boiling near your rear sight?
Cheers
Tinker

shootawayAcraglass but it didn't need bedding is was alright to begin with.Acraglass will melt and boil if the barrel gets really hot-no doubt about that.If you shoot 10 or twenty rds at the range over an hour there are no issues.If you shoot 50 in 10 minutes-well things are going to get hot.It once got so hot that I could feel the heat through my glove and through the padded rifle case on a cold winter day.

a.tinkererShootaway-
I'm not interested in whether or not it was needed.
I'm interested in getting a gauge on your barrel temperature.
You can find out the maximum temperature that AcraGlass will withstand.
From that figure you can estimate barrel temperature.
I'd like to know *how hot* you run that barrel during a typical shooting session.
Cheers

I called Brownells today to discuss the max temperature that cured AcraGlass can handle.
They note that (as most epoxy compounds) AcraGlass starts to off-gas (decompose) just over 400 degrees farenheit.
You noted smeared, essentially liquefied epoxy.
That indicates some seriously high barrel temperatures.
Cheers

Cross LA round every 14 seconds for 30 minutes might build up some heat.
