Thread: 7 WSM or 7/300 WSM

I went with a 7/300wsm to use a longer neck. I burnt out my 270wsm barrel in less than 1000 rounds ( IIRC 750ish).
Also at the time there was a better selection of 300wsm brass than 7mm wsm.
I'm using Norma brass and necking down with a redding bushing die.
Velocity with 180gn bergers is 856m/s so not fast but accurate. I may be wrong but I think the longer neck helps hold the long projectile I have the base of projectile at the neck junction.
I shoots better than I can.
Got to run to squash, but throw some questions and I might be able to answer

So 300 WSM for full length etc then your neck die? I was thinking a 300 WSM type s set then change the neck die sleeve

Ouch. Is that common?

I got about 1100 of best accuracy out of my last barrel running it flat out.
I understand 1400 is about tops for a .270wsm but barrels become consumables when running such high pressures and speeds if you want to shoot targets/steel as well as animals.

Guess so. I have never thought about it. Mines done about 200 so there is a bit of life left. 5 years maybe, and then we will both retire. Or my sons can re-barrel it.

Tahr I shot several mobs of goats. So a lot of the damage was my fault.
Also I was running pretty high pressures I believe. Speed wasn't there, but the powder was.
