Sighting in Rifle Question(s)
Posted on 10/12/24 at 7:27 am
Posted on 10/12/24 at 7:27 am
I've noticed when I try out new ammo for my 308 I can usually find one manufacturer's ammo that will group the first 2 shots tight and sling the 3rd shot. I usually discount the ammo as not accurate when that happens. I'm beginning to wonder if the 3rd shot flyer is a result of the barrel getting hot when I fire 3 in pretty quick succession. This leads me to the next question of how many rounds does it take to heat up a barrel to where it affects accuracy?
I tried out the Remington Corelokt Tipped Ammo last season and this is what it was doing so I didn't use it. I just bought some of the Federal Fusion Tipped Ammo I found at Academy. I've had good luck with Fusions in other guns but couldn't get good grouping from their regular line in my 308. I've been hunting with the Winchester Deer Season ammo, which hold a good group, but was wanting something more bonded or solid.
Also contemplating sighting my deer rifles at 50 yards this season instead of 100. I'm thinking it would be more accurate out to 200+ if I did that.
Just my Saturday morning thoughts. I'm getting ready to break out the rifles and get them ready for deer season soon. Appreciate any of you experts thoughts on this.

How many seconds/minutes between shots when sighting in?
After each shot I point my barrel up to release smoke and open the action. I bought a little battery operated fan off eBay that blows air through the barrel. I wait around 5 mins between shots. I know this is the overkill, but I’ve found it works for me.
I had a Savage 308 that couldn’t group Fusions, but could stack the standard Corelokt in 150gr. Some rifles like certain rounds.
I’d always sight in my 308 at 2” high at 100’

I usually shoot them within a few seconds of each other assuming 3 shots won't heat the barrel up to where it effects the accuracy. I guess that is the crux of what I'm trying to figure out and if anyone has also noticed this with a 3rd shot flyer.
I also shoot the the savage 308. Trophy Hunter/Model 11

I doubt your barrel is getting two hot, but I think you need to give it a little more time between shots. Concentrate on your breathing and trigger pull.

I think that you are flinching on your third shot. Think about it. Every third round out of a random box is not defective.

3 quick shots on a thin hunting barrel could heat the gun up enough to through the 3rd shot off, absolutely. I’ve seen it happen on a Winchester I was helping a friend sight in.
You should slow down if you don’t have a fan.
As to distances, I sight in at 100. It’s uniform on all my rifles and I know the dope on all of the although it isn’t needed for 99.9% of shots.

Run your ballistics through a calculator that gives you the drops/rises at 50/100/200/etc. It'll vary a little by round, but I find sighting close at 50 can get you and easier shot at 200 and you're only messing with an inch or two at 100. I prefer that, and most of my shots at a deer are 50 or in anyway.
3 quick shots out of my 30-06 and it's definitely warmed up. I wait a couple of minutes between shots because I know my shot at a deer will be that first cold one anyway. Which is why I bring multiple guns to the range every time so I can keep rotating and shooting.

I'm shooting off of a sled and I'm not flinching on the second shot that I know of, although I did consider that as a possibility. That's what led me to the hot barrel theory.
I'll shoot 2 that are almost touching at 100 and tell myself I've found my new ammo and then like clockwork, the 3rd shot is 5 inches off from the first 2.

Let the gun cool down for 30min then shoot the third.

I had an old man show me how to sight my 30-06 in years ago.
Draw an + on a piece of paper and get it hitting 1/2 inch high at 25 yards.
It will be close to dead on at 100, then start dropping depending on ammo

How far is the 3rd shot from the other 2? An inch? That could be heat but in reality it's the gun. 3 inches? That's not heat.
You could shoot 10 straight with a hot barrel and it won't walk shots. If the gun shoots it'll group them all in 1.5 inches or less. Bigger than that change bullets.

I think it’s a hot barrel. Many of today’s rifles have very thin barrels. If everything is acting crazy on a third shot fired very close to the other two it’s the only likely explanation IMO. Especially out of a sled it’s hard to have user error there. Space your shots out more and allow the barrel to cool. It doesn’t take much for many barrels to move with heat.

There’s some good discussion on this on rokslide
Rokslide cold bore hot bore test
The short of all that discussion is, a 3 round group isn’t representative of the cone of a gun, you’re approaching the real cone of a gun with 10 shot groups. Like if after your third “flyer”, you shot seven more it wouldn’t look like a flyer anymore. And for the heat, it doesn’t really affect it like people say it does.
I haven’t tested this myself, I’m just sharing it. I will say I’ve experienced what you are with 3 shot groups and since I’ve started shooting more 5 and 7 shot groups, they look less like flyers and more like a real, larger group. Turns out with larger groups a bunch of .5-.75moa guns turn into 1 or 2 moa guns, which is completely acceptable.

A hot barrel should still group 10 shots in an under 1.5 inches. That's plenty accurate enough for hunting as far out as 500 yds if someone is capable enough.

Exactly. Very few 0.5in rifles exist. Anyone claiming they shoot half inch groups all day long are full of shite. A factory rifle will not do that.

This makes a lot of sense. I only shoot the 3 shot groups because that's what I did in the Army and ammo costs too dang much. I should try to shoot more rounds and see what happens.

More like 5 inches. All I know is I have a .243 that I can shoot bullets through practically the same hole at 100 yards with Federal Fusions and am seeking similar results with my 308. I admit that it may not be possible.

Ok so 3 shots, how big is the group? It should be plenty good enough to hunt with. Even a 3in group at 100 yds is good enough to hunt with up to 200 yds.

That's definitely not heat. Check the scope, mounts and rifle. If none of those have issues change bullets.

I didn’t read “ quick shots “. Give time for barrel to cool. Shoot three good shots.
I never thought I flinched. The old Marine that taught me how to shoot said I was flinching. He said let me load your rifle.
He stood behind me and loaded a single round. He skipped a round a couple of shots later and my “ flinch” was obvious.
I had to learn how to “ squeeze “ the trigger. So steady an easy that when the round went off I didn’t flinch.
Get you buddy to load your rifle and suprise yourself.
