Thanks everyone for the input. Does anyone know if there is a deburring tool that fits a 0.59 flash hole. That's the size of my flash hole on lapua Palma brass, as I wouldn't want to make the flash hole biger.
So would this Wilson be a good trimmer, it's the base model I would guess, I size my case necks a little tighter to obtain my accuracy so the cheap lee case length gauge cutter pilot doesn't fit and that's what I'm worried about with other pilot style cutters.
Ok everyone I'm going I do a seating depth test I'm going to load 5 rounds the same starting at 2.800 and up. What increments should I go up in. At 2.830 I had horrific groups....
Ok everyone I shot my same loads just seated deeper to 2.805 and all groups shot the same.. All erratic except 43.7, it was a group of 2 inches, 5 shots at 385 yards. I'm very happy with that, but should one try more seating depths to get better or is that about it?
I'm looking at the hornady case lenght trimmer, what is everyone's opinion on this tool, I also looked at the lyman one, which is better. I've been using the lee cheap one but found it was scratching the inside of the necks.
I'm very excited because I never understood or took into account parallax. I'm betting I didn't have it set right. I just turned the knob until it was focused on my eyes.
If I didn't have my parallax set right could this have made my groups that spread out?
Thanks guys. Yes those groups are shot at 380 or so. Everything I did and used were the same when I did my ladder test. Does that seem likely that I just need to play with seating depth and it could shrink my 42.8 group with such horrible groups below an above the 42.8.
I've been doing some load development for a rem 308 milspec. I'm using lapua Palma cases, gold math primers, imr 4064, and hornady 178 hpbt at an overall lenght of 2.830. A couple weeks ago I did a ladder test from 39.7 to 43.7.gr at 380 yards. The 42.2 to 43.7 all was grouped in and 1.5 inch...
