Vertically string of shoots
 

I was trying to work up a load for my new encore this weekend. I'm have a problem
with vertically string my shoots two inches off the bullseye. I'm using 295gr powerbelt,
with 100gr 777 powder. I wasn't sure if there was something I can do to correct the problem. I have attached a target, I used red dot to show shoot position.


Thanks for any help you might be able to give me.

RE: Vertically string of shoots
 

I think it goes like this: to correct vertical stringing increase charge a few grains,and to correct horizontal stringing decrease charge a few grains.I think i got it right.If not i'm sure someone will correct:D

RE: Vertically string of shoots
 

Also you did not say if you were swabbing between shots.not swabbing between shots tends to build more pressure with each shot hence the stringing as well:D

thats powbelts for ya. I found 200fps velocity spread with em. Lower your charge.

I knew i was wrong[:'(] SORRY!!!!

RE: Vertically string of shoots
 

Not that your wrong, he is getting blowby with those crap powerbelts. Has to lower his charge to get his Velocity spreads down or increase his bullet wieght.

Makes sense

I believe the replies so far are both correct. You're pushing them too fast I am guessing. Try dropping your charge 10 grains and see if that does not help.

Also as asked, you are swabbing between shots I hope? Since you're shooting Triple Se7en I would also suggest that before you load the powerbelt, pull the plastic button off the bottom. You will see a lead spike on the conical that the plastic slips back on to. Put a drop of lube, oil, spit, what ever.. It will help them shed the button faster and give you better accuracy.

If you are shooting powerbelts because they are slip fit loading, there are other projectiles out there that are slip fit that will give you better accuracy maybe. They are .503 diameter 460 grain No Excuses Conicals. I shoot them with 85 grains of Triple Se7en or Goex 3f and the accuracy is exceptional. With 85 grain, that big chunk of lead has plenty of knock down power also.

No Excuses Concials can be found here. The guy is great to work with.

That is a great rifle your shooting. Give it some time it will come around...

Hi,

Thanks for all the replies.

I do swab between shots. I use a patch dampen with T/C No. 13 Bore Cleaner and then a dry patch. I hope that's OK. The reason that I was using the powerbelt was because they loaded in the Encore. I had problems with other bullet, sabot combination on the second shot. I'm just trying to find a combination that is consistent, and decent down range performance.

I will try removing the plastic button and lube it. I have also purchased T/C 250gr shockwaves and hornady 300gr XTP. I'm hoping that I can seat them, after the second shot. I will order some of the No Excuses, and try them, but what kind of range does those 460gr have? That's big, almost a lead mine in it's self.

Thanks for all the help!

Maybe the target is slowly sinking in the mud:D

75-80 grains of 777 and a 295 gr powerbelt is a good load to try. I get good results with it. That 777 is potent....you don't need to use as much.
Are you letting the barrel cool between shots?

RE: Vertically string of shoots
 

I've got conical loads worked up that are really accurate at 125 yards.
With conical, also use a Wad and seat that first on the powder for a gas check.
I love shooting conical.

Also you can use the No13 on a patch, but just plain water or spit will serve the same purpose. When shooting sabot, I always shoot from a bone dry and clean barrel. I spit/alcohol/dry swab/patch inbetween each shot. You may need to swab more or less depending on fouling.

Flinching or pulling/anticipating can also cause a stringing effect. Make sure when the ignition goes it is a "surprise".

Hi,

It was a little muddy out there.

I will defiantly lighten the load. I’m pretty slow at loading it, and it was pretty cool out there last Saturday. The range officer did warn every one that there was no rapid fire,
at least 3 seconds between shots. I laughed.

Thanks,

Mike

I shoot a T/C Black Diamond XR with a 1.5 X 4.5 power scope. This was done off a bench rest at 100 yards. I have since upped the charge to 85 grains of Triple Se7en of Goex 3f and the accuracy is exceptional. Also I do not have to swab when I shoot these. They are a slip fit conical like the powerbelt. All I did was draw a cross in three places on a piece of pine board and put that out at the 100 yard range... I wanted to test some different powders with the No Excuses Conicals. Although Triple Se7en did the best job, I still shoot Goex 3f.

I see no reason why if you practiced with these they would not be good out to 150 yards. With that load of lead, there is a lot of down range energy.

One thing to remember, your rifle is new, but there is no reason why you should have to stand on your range rod to seat a projectile. When the sabot is that tight, it is time to change sabots..... Many times the sabots that come with bullets are not a good fit for your rifle. I found the Thompson Center Mag Express to fit best in my Black Diamond ....

good luck..

Thanks for the reply, and great shooting.

I was having problems loading 265gr Hornady and Harvester sabots. I found that the bullet were .430 44cal, causing the tight fit. I will try the NE Conicals. Should I seat conical directly on top of the powder?

Thanks,

Mike

RE: Vertically string of shoots
 

Yes, seat No Excuses right on the powder charge. I only shoot 85 grains because if you go more the recoil can get a little brutal.

As for the Harvester Sabots in a T/C barrel, get some of the T/C Mag Express sabots and try them. For the .430 diameter I think the green .429-.430 should work just fine. Keep the charge around 100 grains.

I will not swear to this and Triple Se7en is much more up on sabots, but T/C used to be made by MMP I think. I used to have trouble loading Harvester sabots myself.... In fact I broke a short starter trying to get one down the barrel...

Is your breathing correct? Take a breath and let half out and squeeze.One of the first lessons taught by USMC marksman instructors is consistant breathing.
