Good share. I know certain smiths give considerable attention to the ignition system to make it ideal and lots seem to ignore it unless there are problems. I'm pretty ignorant on all the details involved but seems its a good thing to keep on top of.
I believe and know that there's a bunch of barrels out there that shoot worse or to a different POI after heating up but I also think it's far over played. Wouldn’t surprise me if it was a factor in these tests with factory CVAs, savages, and a 300 WM tikka in use. I think there's lots of people...
If you want to shoot to 500 yards I'd look at a bullet that isn't a parachute in the BC department. Even just going from a 150 TTSX to a 145 CEB lazer @ the same velocity keeps a guy above 2200 fps impact speed over 100 yards further out.
What rifle and barrel length are you using?
For "good enough", you can use the WEZ tool to work towards a scenario where ammo/rifle precision has next to no impact on hit rates compared to human error.
Are you trying to evaluate to where you can pick the proper load to win a bench rest competition or hit an animals vitals?
If benchrest - the guys that do well dont' seem to believe in statistical validity anyway :ROFLMAO:
If hunting - it doesn't matter below a decent base level of precision...
^ This was my first thought.
If the brass chambers fine before seating a bullet, it doesn't seem it's a brass sizing issue. If that brass has already been fired without issue, it doesn't seem like it'd be a neck clearance issue. I'd think it's one of the following:
1. your seating die is...
Yep. I bought ibonds when rates were way up including with the tax $5k tax return option. I cashed out recently because the rates were lower than what I can get in a savings account.
