Home Forums Reloading Big Game Rifles 30-06 problems

Ok folks got one stumping me today. Savage 110 30-06 does not like 150gr bullets 3-4 inch group at 100 yards, 165 grain bullets shoot and inch group so I’m loading Nosler partitions 165 grains over 47.5 grains of H4895 CCI 250 large rifle Magnum primer give Constant groups under 1 inch at 100 yards but move it out to 175 yards and it then shoots a 3-4 inch group 8 inches low and 6 inches right. Does the rifle just not like the bullet or do I need to play with seating depth I don’t understand I was guessing it would shoot around an inch low not 8.

Is the barrel being cooled before that 175 yd group? Theoretically it should shoot just under 2" at 175 if it consistently shoots 1" at 100.

No need for magnum primers

Yes it sat till was close to ambient Temp. I know there is no need for magnum primer but shoots a better group with them than it does with standard

Velocity baby velocity. Seen and heard of to many loads that shoot great at 100 but fall apart at the 23 marks. 40% load 60% shooter.

I could go for that if I had not been the shooter. The savage is my brothers gun I was shooting my Remington 700 30-06 with the same load now mine does shoot tighter groups 1/2 inch group at 100 today and 3/4 inch at 175 with this same load was pulling them out of the same bag that is what has me so confused this gun has never been a tac driver but has always been reliable ran Hornady 165gr sst with it for years with out a problem till we started having to many problems with the sst that’s why we made the switch or are at least attempting to make the switch if I can figure out how to make this one shoot something else

Tried other powders such as H4350, IMR4350, etc, changing COAL, tried other bullets (Sierra, Hornady, etc.), checking scope (possible parallax error), checked concentricity of case necks, checked neck wall thickness, make sure the barrel is not hitting the forearm, cleaned the barrel thoroughly? These are but a few of the many problems which can cause the inaccuracy described, best is to check and eliminate them one by one.

Clean the barrel fully.

If that’s doesn’t do it I would say the barrel is suspect.

All I can say is BTDT. My M700 in 30-06 is a tack driver (even shoots different weight bullets into the same groups at 100 EXCEPT it doesn't like 165's Could never get it to shoot any 165 until I tried 165TTSX, then it settled down and shot them fine. Bad juju.

You may want to swap the scope on that rifle, and check the mount screw torque too..

This is assuming you are using a good rest / bags that a rifle sling swivel stud didn’t catch on when firing the rifle.

Something is amiss here.

If, as you say, you are CONSISTANTLY getting less than one inch groups at 100 yards, then you should not be getting the 8" low 6" right groups at 75 yards beyond that.

It just doesn't work that way.

If your rifle will not shoot 47 to 49 gr. 4895 under a 150 gr. bullet there is something very wrong going on with it. Start from the start --------- pull it apart. Take the scope off, take the action out of stock. Re-assemble making sure nothing is binding, barrel not touching anything except the action. Torque down everything 45 to 65 inch pounds for the action. 25 to 30 inch pounds on the ring bases. 15 to 20 inch pounds for the score rings. You get the idea!!!!!

My bet is on a crap scope. What scope is it anyway?

+1 with 30338. Sounds like a scope/mounting system that is bonkers. Only thing I've seen that can cause that amount of change in 75 yards.

Nikon buckmaster 2 4x12x40

Kinda strange. I have the same scope and it groups ok but if you look through it for just a little while it tries to pull your eyeball out of your head. Hate it. Just throwing that out and hope that is your problem. Cheaper to fix than the rifle. Ed k

Clean the barrel. Check all the mounts. Torque receiver screws to 50#. Try a different scope.

I suggest trying all those things listed above + 52gr of IMR 4064 and any 150gr bullet. I have never seen a rifle shoot it worse than 1.5 MOA.

Thanks, Dinny

Check for parallax error and for the scope being possibly canted.

Thank you everyone for the response and great ideas. I went to pull the scope off tonight to try a different one and ship that one back and discovered that the from base was lose not crazy lose could not tell with the scope on but as soon as the scope came off it was very noticeable so i put more lock tight on it and got them thighed back up now to figure out why they came lose in the first place or if it’s just one of them crazy things
