"Some do but you will have to shoot 10 rounds in 4 minutes. Your rifle barrel may or may not hold up to that accurately."

10 shots in 4 minutes centerfire rifle. 6mm-6.5mm cal.

medium sporter, steel, barreled rifle which shoots half inch, 3 shot groups @ 100 yards.

what will happen to accuracy shooting 10 shots in 4 minutes?

versus a heavy straight tapered barrel.

trying to answer the above quote for anyone who wants to shoot a sporter rifle at 500 yards.

With a properly stress relieved barrel I don't think it would matter much.

Hard to say for sure but you'll likely see the groups open up some or POI shift a bit after the first 3-4 rounds .

Bet

I think if you space the shots it's doable, but it's most likely going to start opening up after the first 5 or so. My Tikka CTR will shoot the first 10 pretty accurately but you better let it cool for 10-15 minutes after that, and I'd bet that shots 8-9-10 aren't grouping as tight as 1-2-3.

Most will open up some and the more rounds on it, it'll be amplified. I don't shoot my sporter barrels more than 3-5...I don't have any need too and don't want to torch a barrel any faster than I already do

To shoot a match like that, I always wanted a Heavy Varmint but really preferred a straight contour.

223 not much accuracy wise, 28 Nosler alot

A "Medium Sporter" I would not count on it holding together for 10 shots in four minutes, even in 40° ambient temps.

In 90°+, absolutely not.

Unless the barrel is 18" or less. Then it is a maybe. But you'll have to shoot it for yourself and see what you see.



M24/M40 contour, or heavier, they will hold together in +100° weather.

Customers hunting rifles, I do not shoot more than three consecutive shots, no matter the weather. Then I let them cool completely off before I shoot them again. That is going to take several minutes, even with a fan blowing on the barrel.

The round being shot has a lot to do with that. Run it at 58,000 to 62,000 PSI the round count will be less before losing accuracy will be less than one running 50,000 PSI.

Part of what I like about the Grendel, 50,000 PSI trajectory of a 308 and only burning 28 to 31 gr of powder 10 shot strings no problem at least staying under MOA for 10 shots faster than 4 minutes.

Like Jason said 223 no problem, 28 Nosler, 7 Mag, 7 STW problem along with many other mags. Load workup for the 264 Win Mag takes a while just for the barrel to cool. Take a few other rifles to the range when doing that so have something to do while the barrel cools.

Pretty simple really. Take your sporter rifle out to 500 yards at the temps you expect to hunt in. Use precise paper targets, a good scope and a good rest. Everything else is just conjecture.

true

thanks all for the great answers!

I think you could do it

and remember if you ever get a chance to take 10 shots at a deer at 500 yards, dont go for 11, run. Its a robo deer

Even with a straight contour, or letting a sporter weight barrel cool, it will usually open up some with 10 shot groups. The more rounds in the group, the truer the picture you get of how a rifle really shoots. If you have a rifle that will consistently shoot 10 as tight as it shoots 3, it is special.

Could be some shooter error mixed in there as well.

I knew an old game warden that named his deer “Memorex”.

Ranch I hunted on in Montana they setup the robo deer (big Mulie). One of the ranch employees saw the it driving by, went over the hill, parked on the shoulder, got out crossed the fence and crawled over the hill to where he could get a shot which he did and killed robo real dead. hit right in the controller and motor for it. Nothing wrong with what he did. They usually called the rancher before putting it out but someone forgot to do that. OOPS!

.82 at the muzzle.

You'll be fine, just come and shoot. Your lack of a dialed in hand load will be your biggest challenge.

Agree on both.

.82 is at the muzzle is not what I consider skinny for a barrel.

Bartlein calls a Varmint/Sendero .830" at the muzzle

Definitely not a medium sporter barrel.

Have you ever measured the length of time it takes to cool off enough to take the next shot? I’ve always heard 3 min but don’t know if that’s bogus or not.

I shoot three in a row, on a weekly basis. Almost every barrel can tolerate three consecutive shots, in under one minute.

The next volley is going to be a wait time.

A whole lot of factors come into play.

Cartridge
Ambient temp
Barrel contour

Thin barrel, big magnum, and July, it's going to be 10 minutes or more, even with a fan blowing on the barrel. The 3 minute number you were told is mostly bogus, due to the millions of combinations there can be.
