Thread: Where to from here with my 7WSM?

As has been said the crown looks rough, it also appears that the rifling is damaged/not straight just inside the muzzle (about halfway down the visible part). Maybe the muzzle end of the barrel has opened up slightly when it was threaded.

I'd send it to a trusted gunsmith with instructions to cut an inch off the barrel and rethread, make sure you mention it's not shooting quite right and get them to check the barrel with a borescope first in case there's damage further up. I'd be sending the whole rifle to not just the barreled action, that way the smith will be putting it back together so no issues with mag binding etc.

Before you send it to the smith. alot of Remington rifles unbedded (is it bedded) shoot terribly without some form of barrel pressure point at the very foreend of the stock.. slip a business card up there and then group it.. some may notice some Remington factory stocks have small pressure points integrated into the fore end....
I've seen a .243 700 that shot 2-3" tighten up to 1/4 with that simple trick...

Secondly.. (ya can't fuck it more) you can do a simple recrown yourself before you send to smith with a drill and a case mouth camfer tool....

Delete the thread and put on TardMe...

That crown yuck,chop chop.

the rechamber itself would raise suspicion with me. get a smith to have a look. had a 280 rem years ago and the chamber looked like it had been done with a cordless drill and a masonry bit...

So its been rechambered from 7mm Rem Mag to 7WSM ? That raises the needle on my weirdshitometer.

Greetings,
We have the winner, a badly damaged crown. I am amazed it shoots as well as it does. It looks like damage was done by rough handling. I have no doubt that the barrel is original to the rifle and originally chambered for the Remington short action ultra mag after comparing it with my own rifle. Who knows why. This may have been done some time back as the 7mm WSM has faded with the 7mm SAUM soldiering on in F - class. In any case the rifle is now a bitza but still worth cutting back the barrel enough to remove damage, if required, and re crowning to see if there are more demons from the rechambering. This would let you get some use from your components and dies. Not the answer you were hoping for but it is what it is.
Regards Grandpamac.
PS. The rifle would have originally had a 22 inch barrel. Handloads with projectiles of 150 grains and up would have seldom topped 3,000 fps.
GPM.

Thanks all! I'd assumed the crown would be fine as I've never carried it without the brake on, and I had that put on as soon as I got it... woulda thought the smith who did the threading for me might have looked at the crown, but there you go.

Yes @grandpamac - 22 inch barrel. Didn't want to shorten it further, but needs must.

Will take it down to Gunworks, but I'm also thinking of switching to a suppressor so I'll wait until a secondhand one comes up as I may have to get it re-threaded anyway.

gunworks will see you right..... probably looking at around the $400 mark for them to recrown,thread and fit brand new suppressor.

As fault finding and nothing to lose, try polishing the crown before you get it cut back. This is diagnostics time, as I said you are looking for improvements not a complete fix! Brass round head screw, grinding paste (it wont tear worse chunks) and polish until its even in the light. Try it again and see how it goes - push a patch through to clean everything out and also check for loose ares (bulges) in the barrel and at the muzzle.

Better?

MUCH better.....interesting to see what range result is.

Looks betterer to me, if grouping improves I'd still get the bore scoped before getting it professionally crowned.
