Seating shorter for accuracy?

I had posted not too long ago about my 1st ladder test and got great results. Now I went and loaded 2 more 3 round batches (3.32 and 3.34 respectively) to 2 slightly longer OAL's to hopefully finalize this load developement. Well I got 2 groups higher and spread out quite a bit more than the ones seated to 3.3 and the recoil seemed worse. I did have a 30-06 that loved seating bullets deep. Was this a fluke or a common occurence in your experience? I am going to load 2 more 3 round batches seated to 3.28 and 3.29 (down from 3.3 I ran the ladder with) and see if it works better.

BsChoy,

I do load development in exactly the opposite way. I start out with the bullet seated out as far as possible. My OAL is either restricted by magazine length or throat, and if throat, I'm at 0.010" off, and then I play with charge weight.

So do you think I should seat the bullets out further? I have a good amount of mag space left so it wouldn't be an issue. I got a tighter group with this charge seated to 3.3 so it would make sense if it shot better seated further out. I guess its time to play around with it a bit and see.

I seat my shorter than recommended simply because I need to get them into the magazine. If I seat to recommendations, they don't fit.

BsChoy,

If you've got an accurate load, I wouldn't worry about the OAL.

At some point in the process, one should say, "good enough, good to go".

When you arrive at a sufficiently accurate load, and verify its numbers over a chrono, then I think you have arrived! :)
