When I was a kid, 40 years ago, I bought a cheap Anshutz 22LR. It was cheap compared to all the other Anshutz rifles at the time. It doesn't feed great, even after thousands of rounds through it, but it shoots just about anything amazing. I can sit down at 50yds and literally shoot out a 1" dot...
I shot that same bullet for quite a few years in my 375-358STA. Mine was running 3080fps in a 27" tube with 4350. It hammered all kinds of animals from a duiker to a kudu in Africa and antelope to elk here.
The head to the belt dimension sets the headspace. Trimming the neck wont fix that problem. It sounds like those cases have too long of headspace dimension for your rifle. Belted cases have been known to have terrible tolerances in the belts. The "premium" brass made now is much better.
Today my Draht puppy went 31 miles and I went 5 miles. I don't have a GPS collar for my lab but I bet she is half that. My youngest son and I got 4 birds and he shot a bird with a 22" tail. One of the better birds this year for planted birds. I shot a 24" a couple weeks ago.
My Drahthaar puppy probably does twice the miles my lab does. He is like a crack addict with ADHD. I talk to the owner of the brother to my dog and he tracks his dog chuckar hunting. He walked 9 miles and his Drahthaar puppy did 29 miles. That's burning tons of calories.
I've done a lot of experimenting with food recently. My Draht puppy was raised on Inushuk dog food out of Canada and when I was ordering it from Chewy both dogs seemed to do well. I reached out to the owner of my dogs brother and asked if he was interested in splitting a pallet, 65 bags. After...
I got into 2 birds this morning and my Draht jumped one early. The other one jumped when I was tangled in some trees and couldnt even get my gun up. I did get 2 yesterday though.
Have you tried going out to the Calculations page and then back into the specific calculation program to see if it will reset? Sometimes it saves info from the previous session but if that doesn't work you might try refreshing the page itself to see if it will reset. Otherwise you might have to...
All of the issues with sizing brass in the PRC chambers is using tougher brass like ADG and Lapua. The die to chamber dimensions are too close for tougher brass that springs back more coming out of the sizing die. when the brass is too close to the chamber size it doesnt spring back enough to...
We did tons of rockchuck dispatching in the 90's with about anything you can imagine including 375 H&H, 416 Rum, and 460 Weatherby. The problem is the bullets from the big bores are too tough, without modifying, to get explosive performance like a varmint bullet. We shot tons with .30 cal 150gr...
JBM will do data in about any increments but you can't pick certain drops at various distances. You can pick odd zero distances just nothing like -5.00" at 406yds. If you pick 10 yard interval distances you could probably figure that out though.
I built a 30-378 Imp with a 30" barrel years ago. It shot 150 Ballistic Tip over 4000fps, 165's 3900fps, 185's over 3600 and 210's over 3400 with WC872 ball powder. Mine was a caliber length neck, 35 degree shoulder, and minimum taper.
