Yup cut into the fluting when I went to 19, some people said not too but majority said it’s fine and I’ve had no problems.

Tikka 300wsm cut to 20inch,Dpt can,178eldx getting 2890fps with RL17

Here's an update of how things progressed.

I eventually cut the barrel to 21 inches and suppressed my rem mag with a dpt. Talked to a few people and got some reloader 23, 162eldx and loaded them to the same length as factory precision hunter ammo. Did a ladder test starting at 63.5grns and working upto 65.5 grns. All shot well but 65 grns shot exceptionally well. So loaded up another 15 of these and went to the range, zeroed at 100 then shot a group at 200. The 100yard group was 1 hole and 200yard group was. 393 of an inch and dropped about 2.6inches from my 100 yard zero which gives me a speed of approximately 2900fps (il verify this out further), but pretty stoked with the result.

Defintely don't regret chopping the barrel and suppressing as it's alot more pleasant to shoot now and accuracy improved.

That's worked out well for you, sure is shooting well.

Love my 20 inch 7mm saum
Many years ago Robbie Tiffen cut a 7mm rem mag down and re reamed it to a 7mm wsm, probably the most accurate rifle I have ever owned.
Could be a good way to go if you could get a Smith to do this for you

My 7mm saum has an 18inch barrel, throwing 150 bergers @ 3000 is fps. Ragged holes at 100.

My 19 inch 300wsm is certainly no hot rod but with a very mild load (2782fps) it'll consistently put 3 x 178gn eldms in a ragged 1 hole group with ease.
Same load 2.75" group at 500y in less than ideal conditions
Pleasure to shoot and carry with the suppressor and more than enough poke for what I use it for

Used a couple of model 7 7mmsaum cut to 16 inch

3000fps with 140 AB or NBT

Factory mod 7 saum barrels shortened often return exceptional accuracy that they lacked at their factory length

Mag fit loads?

Talk about a thread revival

Just curious is there anyone in NZ that would/could fit dual ejectors on an a7 bolt ?
Same issue with my a7, have seen on usa forums dual ejectors fitted as a solution as it seems to force the brass to eject more horizontally so it doesn't hit the bottom of the scope and fall back into the action ? Although you never loose your brass which at $4.30 a piece isn't a bad thing

I can’t see why not @dannyb lots of smiths are fitting the sako style to the rem bolts gunworks is probably the outfit to speak to could be worth asking next time your stopping by

Might not happen but keep in mind more aggressive ejection could cause the case necks to be dented on the inside of the action (not that I consider this to be a problem, but some treat their cases with more care than a newborn child... )

I anneal my wsm cases every time, not worried about dented necks, far less force exerted than firing off 60k psi
