I have had a nagging suspicion since 2020 that this incredable reloading inflation is partially because of the amount of new reloaders.
I've been sitting pretty since Obama taught me to buy in good times. But new reloaders post 2020 really have no idea what primers and powders are supposed to...
I have had/ have three 300wsm barrels. The one thing I've definitively learned is Standard rifle primers produce better precision than magnum primers in this cartridge ( same for 6.5, 270, 7mm wsm).
My current 26" 300wsm has two great loads.
180gr Elite Hunters and Reloder 16.
180gr Ballistic...
Damn right.
I set it up a few inches in front of the brake per instructions the first malfunction... jarred the freaking guts loose.
That RUM might cut it in half even with the brake, lol.
My labradar got destroyed on its second range trip... 300 RUM 230gr N570 and a big brake! Got repaired and have used it every range trip for the last 6yrs. It's read about 97% of all shots. The bluetooth app is unusable.
I really like it to calculate the actual BC instead of relying on listed...
The throat after fire lapping obviously lengthens measurably, ask yourself what dimensional changes happen to the bore diameter. .284 bore fire lapped to remove fire cracking might be .285 or more.
Just a thought.
I used Win 300wsm brass for my first 7wsm, I found Norma 270wsm for my second 7wsm.
It sucks, it makes the 7wsm short neck even shorter when it's all done. But at least I have brass.
A couple of years ago Hornady made a batch of 7wsm.... I'm not doing Hornady for anything.
I think you can relax.
If you follow the condensation trails they go from one airport to another airport.
Because many flights go from one to another multiple times a day and the wind is moving them in a certain direction. That's the uniform patern.
Congratulations! Don't know where you hunt in SE TN but I got this buck in Hardin county last night.

Got outstanding performance in my 300wm this evening! 275 yards in the elbow crease.
77gr Reloder 23 at 3300fps.
I was very scared this load was too fast for a light bullet for whitetail. But he hit the dirt hard, no unnecessary meat damage.
I try to use 180 to 215gr out of my 300win mags...
Yotes on my property either intentionally get sprayed or kill skunks and roll in their stink!!!!!!!!!!!!!!!!!!!
To throw off their own scent. I can smell them coming.
Except 7.62 51 probably doesn't get gm215m, CCI250, Rem 8 1/2 or WLRM primers.
I didn't know where they went, maybe their efforts are all on non magnum large rifle manufacturing.
Not sure if we're still talking about chamber length but....
Here's some of my max chamber length guages. I cut half the neck with a dremel, debur and chamfer. I ream the cut off piece to about. 001" tension on a bullet.
Seat a bullet in the case.
Chamber and carefully extract, measure and...
My advice is, do not try to make a 6.5 Needmoor a 26 Nosler. Like making a Mazda a Corvette. Lol.
Powders that are too slow for useful barrel burn curves will soot your bore horribly (and cause hard carbon rings) and cause unnecessary muzzle blast and recoil.
The only sensible solution is to...
