I have 2 - .30-06's. One I have had for quite some time. It is a late 1960's vintage Sears Model 53 (Win Mod 70). The other is a Savage 110 (Pre accutrigger). I have a good load worked up for the Sears, 57 Grs H4350, 150 gr Speer Hotcor. I have never been able to really get the .30-06 to shoot well. I gave it to my dad for a while, and just recently gotten it back. Previous to me giving it to him, I had adjusted the trigger to get the creep and over travel out.
I shot both the other day. I could not hit paper at 100 yards with the Savage with either the handload or Win factory loads. (This could be a scope issue and I plan to try another scope on it). I also noticed that on both loads, the primer strikes from the Savage seem different than the Sears. The primer seems to flow around the primer strike area, but the primer is not flattened as much as with the Sears. I worked up this load in the Sears and backed off from max (about 60 grains), and the load with near minimum for this load, depending on the manual, and the Savage should be a stronger action anyway. It all just seems odd to me, or are these strikes normal. I have never seen a strike like this in any of my guns that I am aware of. They almost always come out more square/flat rather than the primer strike flowing as it is in these pics. Any help, suggestions, or ideas where to go from here would be helpful. Thanks, First pic is the handloads - Savage on the left, Sears on the right. 
Second pic is the factory loads - Savage on the left, Sears on the right. - On this pic I actually put them back wrong in the box after looking at them - the order is off, but it is very clear which is which.

Quoted:
It appears that the hole in the Savage bolt head that the firing pin passes through is a little larger that the one on the Sears. That's likely what you're seeing. Keep looking for things like bad scopes, and loose mounts. Thank you. Also I noticed a typo. The Sears shoots well. The Savage is the one that has always been difficult. |

Keep looking for things like bad scopes, and loose mounts. Yep. Either the FP hole is slightly over sized or the FP is slightly undersized. Looking at the base of the case and rest of the primer I see no indications of high pressure, I wouldn't worry about the tiny bit of primer flow. Have you tried shooting it closer? maybe start at 25yds, see if you can get on paper and get a group. |

I'm wondering how this is a reloading question? Sounds like a rifle issue. Not a reloading problem. Because I'm human and figured this would be the best place for it because the reloading folks often have more knowledge when reading primers and understanding what the signs are. It can be moved if you wish. No skin off my back. |
