And the gun shoots all over with factory ammo....shooting with the fire controll lead slead.... And I still can't get this big prick to group
Any recommendations please private message me back
I'm using 180 gr bullet x (Barnes triple shock) loaded factory ammo
Any help thanks fellow shooters...... Davide
 
1) check screws on rings and bases and your action screws.
2) check crown, chamber and rifling for obvious burrs or defects
3) check stock for any unusual stock-reciever fit
4) try with different scope
5) bed rifle
7) have another shooter try
6) if it still doesn't group after the above I would sell with full disclosure.
 
Rob maybe nails it. rings can be a good start. we had one to set up a while ago and it took us few answers from Leupold before getting the right solution.

not the best caliber i loved to shoot.

I had one and got rid of it, I felt it wasn't worth the extra cost of shooting it for the slight velocity advantage I got over my 300 wby and 300RUM. I had accuracy Issues with Mine also. I found only on load which my rifle liked after wasting a few boxes of factory ammo.First, check all the action screws and check your scope base screws and put Loctite on them!!! The load my rifle liked was a federal 215 primer, a barnes 180 gr TTSX and Retumbo. Use the coal out of the barnes manual. The best accuracy I got was around the max load. This load worked in a friends rifle too. Give it a try, Good Luck
 
Just a heads up. Sometimes no matter what you do a rifle is a dud. I had a friend who bought a Browning X-Bolt and tried everything to make it shoot. Finally a gunsmith figured out the the chamber was reamed off center from the bore. Not noticeable to the eye from factory, but devastating to accuracy.
 
Quoting cam1936, "rifle is a dud." Until it happened to me recently, I thought that was unlikely with the state of today's technology. Boy, was I wrong. I bought it from a major specialty retailer. They tried to be helpful, but their answers were obviously from a script. The retailer was fair and told me, frankly, an exchange will not avoid the problem. You read between the lines. It isn't tough. I traded for another rifle. A great improvement in terms of accuracy, but it will be the LAST American-made rifle I ever buy.
 
Boy, that Leadsled set off alarm bells.
Try another scope as these sled gizmos can pewch a scope toot sweet.

Lots of arguments on this, but it happened to me on two scopes and a feller
gummutter too.
No coincidence on this either.

Before you give up on the rifle, find a reliable single X optic and give it a whirl.
 
I believe Weatherby has a 1.5" 3 shot group guarantee for their rifles when using their ammo.
 
Mine shoots well with 220 grain Sierras not so well with lighter bullets. I've never shot factory ammo out of it so don't know how it would shot.
 
Is it a new rifle and have you had it apart. Sold a new accumark in said 30-378 a few years ago and it shot well new. The buyer disassembled it and it would not soot so he sent it in for Warranty. Paul retorqued the guard screws and it was fine again. Apparently the torque is very critical on the guard screws. It's worth a try

A pal of mine had a MK-V with an improperly cut chamber, and we subsequently discovered this problem wasn't unheard of. Examine your fired brass for abnormalities which might indicate the bullet is not being chambered in line with the center of the bore. Lopsided necks, or uneven shoulders indicate you have a chamber problem.
 
When I got my Vanguard 300 Win it had the original factory wood stock. Average group size, on a good day, was about 3". Stock incorporated a pressure point at the front of the forearm. Instead of mucking with it, I bought a new synthetic that was made for free floating the barrel. Groups shrank to well under 1", with factory ammo.

Occurs to me a 30-378 barrel probably gets toasty pretty quick, which certainly could affect accuracy if not free floating.
 
Every time I hear a story like this , with a really high intensity caliber, first thought that comes to mind is, he's flinching, lead sled or not. ;)

A braked 30-378 is not a difficult gun to shoot from a bench or even prone, I know because I have one. I remember doing 30rds of load development with my .340Wby one afternoon with various 250gr bullets. Un-braked Euromark shot from the bench in a T-shirt. Shoulder was black/blue the next week but my best load showed up on the last group shot. Shows there was no flinch influencing the results. If a lead sled is needed to shoot a gun from the bench then maybe you've got more gun than you can handle. Lead sled's are also hard on stocks, scopes and mounts, check all these again before returning to the range.

Mine shot terrific with Weatherby factory 180gr BT's. So much so that I haven't even spun my 30-378 dies in the press. Maybe give these a go?
