Need some FTR rifle reloading advice

The story is that the ORA separated from the DCRA for some reason. (Does not make sense to me how that is even possible.)
Again... I hope that is not true... If you know different, please clarify.

Heard some ORA board members got voted out from being DCRA board members and some other non starter issue...

- At issue The ORA would have zero access to any military range.
- DCRA controls the military ranges across the Country including Ontario.
- ORA would lose any standing to DCRA events (Nationals, Easterns /Westerns)and
- Shooters in Ontario would lose the opportunity to be a Team Canada Member.

I hear they ORA and DCRA are working it out

Cheers

Thank you all for the replies, between this post and the emails received from build gunsmith, I now know well what needs to be done and how to proceed with it.
And 200 SMKs 2231 or Berger 200.20x are not the answer.
Cheers!

ps : will post build pics and target results once my new bullets get in....
 
If your CBTO of 2.360 has a 0.020 Jump, then I'd say that you have a fairly long throat.
Might be too long for the 2nd gen 200 MK. .... ?

I mentioned in some of your other threads that my optimal depth is around a 0.030 jump (a CBTO of 2.165).
In the pick below, you can see through the cut out that the entire bearing surface length is in the neck.

I choose my barrel and chamber reamer with this projectile in mind... Before the build began, my research and the advice of others that use these projectiles was a short throat. My gunsmith had recommended the 308 US Palma Team reamer from JGS.

One last bullet choice.

I continue to forget about the 210's but both Berger and Matrix (currently closed) make good bullets in this weight class.

Great idea cutting a window into the brass case to examine what's going on, I like it and will steal this from you!
Yeah 2.380'' touching rifling is quite a ways long to be honest.
Tried 2 different methods, with a sample of 3 each, and got to the same exact number to the thou close every single time.
There's no doubt about it, that's where I'm touching rifling.

Will look into it.
Tom at GBT was shipping a Manners stock to me tomorrow, so I got him to charge me and throw a box of the new 208s at the same time.
I really feel like these are the answer!

With this new Manners stock my long range carbon hunter in 6.5x47L will be finally complete.
Another one will need tuning!
It's got the same chamber as my 6.5x47L PRS setup, at least I'll be in known territory.
 
I'm not an f-class shooter but since your barrel has a long throat and you don't want to rebarrel. I'd just try a longer bullet to reach out to your lands or leave it as is if you feel you have enough neck tension to keep the bullet from getting bumped and having run-out issues.

If you are single loading and carful with your ammo I can't see it being a problem. Not sure I would run those in a magazine.
 
I run about a .145" freebore with the 200smks which puts you about 3/4 of the way down the neck. Those 208 bergers should fix the issue if your gun doesnt like them try the 215's.
 
Just got my Bergers in, but had to go back to work.
Quick pic shows 200 SMK to the left, berger 208 to the right

We can visually see the difference in bearing surface.
Will have some lenght testing done this evening.

Edit, did some bullet seat depth measurements tonight.
Definitely more bearing surface and further out ogive.
In full JAM, I am now 2/3rds engaged into the case neck, that is bearing surface excluding the boat tail.
I now consider this acceptable.
