On your post of June 17th, you said: I don't measure OAL. Instead, I take my measurements from the ogive. With my RCBS comparator, I'm showing .130''
I also am working up loads for my Savage 12 FCV w/26" barrel, so I read your post with a lot of interest, but I am not sure what you mean when you say "I'm showing .130" Do you mean to say that your are seating your bullet 0.013" from the lands? or are you saying that you have 0.130" of the bullet in the cartridge case?
When I look at the measurements that I have for the Hornady 40 gr. in my rifle, I get a measurement of 2.041" to the lands and if I back off 0.013" that would make it a ogive reading of 2.028". I am using a Hornady Lock-N-Load straight O.A.L. gauge and a Hornady comparator to get the ogive. Does that sound right to you?
I have been working up some loads H 335 and did not like the results I was getting by using a setting set back 0.040" from the lands. I then changed powders to Benchmark at the same set back (0.040") when I realized I was chasing the wrong variable. So I adjusted to 0.010" set back form the lands and improved by 15% to 45% over the prior groups. I am heading to the range tomorrow (God Willing) and will be trying the same Benchmark loads set at 0.005" off the lands but I am a little concerned about how much bullet is seated in the cartridge which might give me too much run out (which I can not measure here).
Any help you can give me work up to a better seating depth for the Savage 12FCV will be appropriated.
