6.5x47 throwing third shot

[jimbo_10x]

I know this sounds stupid but I keep chasing my tail and cannot figure it out .
6.5x47 benchmark barrel , trued 700
130 eldm jumped .020
450 cci
Varget
.002 shoulder bump
200 yds
Shot off a bench with a rest front and rear
No wind .
Shot this today . ( load development ) Puts 2 in there good most of the time and throws out the third .
cannot figure out why this is happening . Any advice ?

Try different seating depths. If it doesn't tune in, change powder. This is all assuming you have no question about your skill or the rifle/optics functionality. Do you have group pictures? Does it go the same way out everytime: i.e. two together, third is at 4 o'clock?

Reads like the first two shots are the ones together. Temperature issues or a pressure point affected by temperature???

Try this. Only take those first tow shots. Then wait a while allowing things to cool. See if there is a #3 and #4 in the same place. That would be a clue of a temperature issue or a pressure bedding issue. Good way to eliminate that as a possibility. Only problem I envision is having the same conditions after a rather long wait.

Load seems warm to me. I shoot 37.0 varget with a 130 vld berger. Some of my rifles won’t shoot hornady bullets too, some will. I would start at 36.8 and work up 0.2 at a time and see what happens. Also might want to try another bullet just to see....

 

[Dusty Stevens]

Id like to know where the 4th and 5th shot goes and if its the third every time. Id also like to know what would happen if you shot the 2 together then waited 5mins and shot the 3rd

 

[jimbo_10x]

Ill try shooting 2 then shoot 2 later .
Yes I am on the upper end of pressure . 38.7 gave hard blot lift and extractor mark , pierced primer .but 38.4 all signs went away .
37.5 normally shoots good but this is a new lot of powder has opened it up .
I feel as though I am a efficient shooter but am always trying to improve .
I have a fairly new sightron s111 8-32 and
My trued action is bedded in a good stock so I don't think my equipment of faulty but I cannot rule anything out 100%

 

[Sandstorm]

What speeds are you getting with 38.4gr of Varget....All my accuracy went away trying to push them too hard with Varget.
Id come down with the powder charge ther's a good solid node around 2760...just my experience for what its worth
with my 6.5x47 and the 140gr Bergers....dont know about ELDM's ...

[jimbo_10x]

Yes I agree, bad shooting form and habits can creep in if your not careful ,
I'll check my base and rings . I have a new spring in it now but might put the old one back in .

I have a small fan set up pointed at my barrel when I shoot my 6.5x47L. My groups stay pretty consistent.

Load development ? You should only be looking for location /poi of the center of the group in relation to the groups on each side of the charge weights being observed, in addition you should look at smaller increments of perhaps 0.2 gr
Not knowing that caliber puts me at a disadvantage however I would agree with those who suggested (those ain’t flyers they are your group.)

Whew, those are big groups for a 6.5x47 and they're kinda all over the place. In my experience, no amount of tweaking the powder charge or seating depth makes 1.5" groups shrink to <0.5" - I think you've got some other problem here.

I'd check and make sure action screws and scope mounts are snugged down correctly and you have no movement when you push and pull on things. Be careful not to over tighten your scope ring caps. Small deformations of the scope tube can cause the mechanics in the scope to misbehave. This sounds funny, but make sure the barrel is screwed on tight and hasn't worked loose. What type of rifle and shooting position/rest are you using? Both for my own selfish enjoyment and to be able to make suggestions on what you might want to check, could you post a picture?

If everything on the rifle looks good, then I'd go back to your reloading equipment and start diagnosing each piece to make sure there isn't something wrong. Just for example: Do the 130ELDM match your seating stem reasonably well? Are you using a bushing FL die and you locked the bushing in and didn't allow it to float? Is there a little crud in your shell holder that is canting the brass at an angle as you size it and again when you seat a bullet?

 

[Ranger188]

Does your barrel have a brake or tuner on it?

 

[jimbo_10x]

Yes , has a little bastard .

I have a good mechanical front rest and leather bunny ear bag in the rear filled with shot . The action it 100% bedded and properly tightened in a bell and Carson medalist stock , barrel is a benchmark and is fully floated , lapped luggs and action face trued . Timney calven elite set at 10oz.
Lapped steel scope rings tightened to 20 inch pounds . 8-32 sightron .
Full length hornady match dies with eldm stem.

Take the brake off for starters.

All mounts and rings need to be double checked and snug.

Reduce your powder charge at least 2.0 grains and work back up to 37.0/37.5.

Your rifle is pillar bedded. Try different torque settings on your action bolts. 65 INCH pounds is standard for a pillar bedded rifle. You can go lower.

Something is wrong if all of these fixes have been addressed and it still shoots like that. RE-15 is a known good performer in 6.5x47mm, so is H4350 and RE-17. If a good cleaning and different powder doesn't get results I would contact the gunsmith involved.

 

[Ranger188]

I was asking about the brake cause, sometimes it becomes just a touch loose or it's
put back on after cleaning and not threaded to the same place as before.
Or not cleaned and something touching the bullet as it pass it.
Eliminate all the easy stuff or even something you don't think it could be, first.

 

[jimbo_10x]

I been trying everything but have not figured it out yet , I thought about tearing it all down and putting it back together from scratch .
If it was just grouping bad I could understand it better but to shoot the first 2 really good most of the time then throw one way out doesn't make sense. I try to load very carefully pay attention to detail . I have my own range so I'm not rushed to shoot or bothered by other shooters .
If someone else ask me this question I would tell them to practice more !! HAHAHA

 

[BoydAllen]

Some years back, a friend and I were working up loads for a fancy rifle that was driving us batty with thrown shots in test groups. It turned out that the culprit was a rock hard rear bag. That particular rifle did not like a bag filled that way. Another thing that I would try is to reposition the front bag a lot farther back on the stock.

 

[jimbo_10x]

Iy had crossed my mind about the bag being filled with lead shot making the gun kick away during the shot because it is to hard .
Normally my guns shoot good with the setup I have but I may try another bag with softer fill .

 

[Ranger188]

I had a 6br that started to shoot 2-3 in one hole then shoot 2 more in into the same hole just 1/4 inch away.
drove me nuts, changed load did everything everyone here has said to do. Had a friend tell me to
check the scope. I haven't heard any problems with this scope. Sent it in to the company and
sure enough the reticle was shifting. Sent back to me and problem was fixed.
You could check this if you have another scope to mount. Don't have to zero it, just see
if you can get 3 shots without shifting.
