Out of curiosity, who will ream a Tikka barrel these days?
When i wanted mine done neither Gunworks or Hardy would do it.

And the 7mm Lazzeroni Firebird for sheer madness[emoji6]

Dave Ward in Dovedale does. He’s doing one for me as we speak - 7-08 to .284 Win. The last one he did shoots 162s ELD-X into .5 MOA 5 shot groups. He knows what he’s doing.
I still think the idea of hand feeding 180eldms will be the way to go. Guy i know shoots them out of his 280ai at a touch over 3k and on his last trip shot 1 tahr at over 1140yds(I am 99% sure of that figure). If you can even shoot them at 2850 you will have 1350ft/lbs~ and be doing a touch of 1800fps @ 1000yds which is more than enough to knock over a big red.
the 8x68s case is a really strong non belted case you could neck down :wtfsmilie:

@ChrisW Thanks for that authoritative advice. Norma state the 338NM and 300NM were designed to swap out in actions made for 338LM.
Do you think the 300NM would work well enough in the Sako 85 long range XL action or the TRG M10 ? Come to think of it. Are those in the pipeline as factory options ?
Bit of an update, Dave Ward does, but doesn’t have the 7BM reamer. And Arthur Clealand does, and has quoted me $350 to rechamber, including a bit extra to get the reamer... bargain if you ask me
@Stocky thanks mate yeah will do, have had a good look around and found that there has been two revisions of the CIP standard reamer, Rev B has a freebore measurement of .3645", whereas the original freebore of Rev A was .0631". I’ll confirm what I need with Greg.
I've read most of the thread and hope.i havent missed this, as the rifle is you should be able to get the 162s to around 3050 fps, with running those numbers how much more are you after from your rifle?
You’re quite right, the 162gr eldx is great and comfortably gets me to 1000 yards. I ran a ladder test last week, and although the chrono was on the blink it looked like my top accuracy node was only 2920, which isn’t quite there. The goal, and that’s it a goal, would be to have a cartridge/rig capable of 1 mile on steel, and enough energy to take an animal at 1Km. With some great advice, I’m going to work up a load seated out to the lands (a couple possibles I’m working on) and single load to see if it’s worth taking the step up.
I would go 7BM ratter that RM if I was to build another too.
Spoke to Tracy at Deadeye, he suggested 7 LRM as a straight rechamber. $350 to rechamber, $200 for dies and $3 a pice for the brass. So for $1000 I could fit the atlasworx DBM and ASICS mags (to run max 3.6” COAL), have the work done and 50 brass. Sounds like a great cartridge, has slightly more capacity than the 7 BM, and a long neck. I understand that the brass wasn't the best, is this still the case? Is there any one out there with this cartridge that can give some real world velocities, and loads?
IIRC, brass is made by Hornady and is reputed to be poor quality. It’s a good cartridge in theory but has largely failed to gain traction due to poor brass quality.
Work out which projectile and velocity is required to get the job done
Make sure your chosen chambering has the best quality brass
To be effective past 1000yards use the best components made
Then for the next year be prepared to be schooled by the wind
