Bearing length

[Sth Oz Dan]

I thought I had my load for 35 Bergers nearly fine tuned. 2 3-shot groups with O.A.L. .01" apart at .55" and .38"
But I ran out of bullets. So I ordered some more and can't get close to those groups.
Luckily I kept 1 of the old batch, and I measured that against the new. The new ones seem to have a 0.01" longer bearing length.
What to do with that info

I measure from base to ogive with Hornady comparator, so I thought that should have eliminated that difference.
But I guess the base of the bullet is now 10thou deeper.

So I'm thinking the next step is to seat 10thou longer?

Any suggestions?

Ah the fun of experimenting.. That just might do it. I am not sure, but it would be worth a try. Bill K

Seems to have done the trick.
I'll probably recheck some loads at the original depth to see if I just had an off day, but 3/4" 5 shot seems fairly acceptable for what they're coming out of.
Now, what else can I test
