Being on the annual safety plan it's cheaper for me to keep it as I rarely go over the allotted messages.
I think right now it 11.99 a month and would be 14.99 to go to the comparable plan (with more messages)
Just did 23-24gr varget yesterday under a 75eldm 150fps difference.
Should be said that with rounding to 1/10gr +/- you are getting up to 3/10 variation in charge weight.
So in that scenario roughly 45fps.
I think in same lots 40-50fps ES seems pretty normal.
I posted recently about 2 different lots of 6.5cm Precision Hunter having a 140fps spread between them. 2560/2700
Since you're trying to bump the shoulder I would imagine you have a headspace comparator? Is the fired brass shoulder you're trying to bump longer than saami spec (i.e. the die)?
That's really weird. Take the collet out with the stem. That's the only thing that could stop it if the neck was too long (and it would have to be really really long). Other than that the only thing that can stop it is the shoulder itself.....
Might have to hit it with your big purse 🤣
2750-2800 with the 77/75. 18" barrel.
Don't have chronograph data for the 69smk but if I had to guess in the low 2800s. In my data book they were lazers with the accuracy. 20" barrel.
