I will compare springs too.

JE, Challenge accepted. I will run some through the Oehler 35 with both. That would be a good thing to know. If I learn a path to better and more consistant ES from this it will make it a worth while venture.


Thanks Jeff.

It would be good Info with hard evidence like the chronograph.

Like you, If it works out to be true and not just the opinion of a great shooter (I never saw the
test results that proved it to be the case.

The Smith/BR shooter that told me the effects of light firing pins always said to me, "Don't believe
anything you hear and only half of what you see" So I have no doubt he believed it but proof would put it to bed.

Re: Primer strike issue 700 Rem

Bear with me on this. I used to shoot NRA Black Powder Cartridge Rifle Silhouette matches in Missoula MT. I usually fared pretty good. One such match on the second day, I couldn't hit a bull in the butt if I was standing on his back, even the day before I did well. Mike Venturino whom many of you may know of from reading his books or articles came to me and said "Jeff, check your firing pin, I am betting it is broken". He explained to me that if the pin did not strike the primer with the same force the primer would ignite differently and would therefor ignite the powder charge differently affecting its burn and thereby changing the velocity and of course changing where the bullet impacts.
To make a long story short, I took my block apart, (this is on a 74 sharps) and my firing pin was indeed broken in half. Mike happen to have a new one, I put it in my rifle and things went back to normal. I am a firm believer that a firing pin that had light strikes will give you wide ES compared to a good hard strike.

My 1.5 cents worth.
