There are a couple posts already regarding this issue. They are:

LOL, I think he's just setting up the thread so as he works on it he can edit each post with his steps and have them all listed on the first page. It should be really interesting to see how it develops. I look forward to pictures Dog Down!

Berger (I know you're using Barnes) suggests a minimum twist of 1:11 up to their 210gr VLD's. I'm sure using that 150 TTSX you've got more than enough twist. Even if you're over-rotating it, it's not like the jacket's going to fly off of a Barnes, they're solid copper.

I picked up a set of the hardened screws from MT. I'm not looking back. I stripped out one of the factory ones torquing it down to 35 inch pounds. I'm hoping it was either a soft screw, or a really sharp bit, but either way, I got the first set of hardened screws they shipped.

I just checked and Witt Manufacturing makes their brakes from 416 stainless. It's the same stuff a lot of after market stainless barrels are made of. You're probably fine for some time Eric.
Vixty on the other hand with the Kahntrol brake (I can't access their site due to my antivirus detecting malware and blocking it) may have an issue. Theirs are apparently made out of machined aluminum. I'm guessing his 300wm is throwing some exceedingly hot gasses which is melting the baffles and is going to lose brake effectiveness down the line.
-
What is that thing MADE out of? Also, what's with the line around the center? It looks like what you'd find on injection molded plastic parts.
The brake DOES look like it's functioning though.

In my experience on this forum, Eric doesn't mess around. I picked up a Redding competition set with a bushing style neck sizer and micrometer seating die. It mentions not compressing loads, so I won't be able to do that. Haven't been able to use it yet since I don't actually HAVE a rifle in that caliber though. Still waiting on the new barrel which won't be till late summer.
I was going to seat my 7mm 180 Berger Hybrid Targets a couple thousands off the lands and generally play around with it to see what works best. Looking forward to Robert announcing the new longer bottom metal with 3.6″ COAL availability. I think he said June. IMO, June can't come fast enough.
As far as powders, I've seen the 4166 and new Enduron line from IMR. I've got a bottle of 7977 waiting for a 695 in 6.5-06 to get back from the smith. Apparently when it was done 20 odd years ago, the smith didn't know too much about the cartridge and never polished the chamber. We've had tool marks on all brass and it's been a bear to get some rounds to extract. We're hoping it's just a simple chamber polish, and not a set back 1/8 inch and re-ream job.

You might also try CFE-223 from Hodgdon. You're shooting Barnes which iirc are solid copper, so a powder that helps limit copper fouling is probably a decent choice. Velocity on Hodgdon's site list is comparable to slightly higher than Varget, with CFE-223 starting loads at 46gr and max at 49.5gr.
Either way, Varget/RL-15 are both fine for that round. It's basically a coin flip. Alliant doesn't have data specifically for the 120gr, the closest they have listed is 115gr with a max charge of 46gr.

You're probably ok with this set up. I've got a Viper HS 6-24x50mm with lows, but on a rail, and it doesn't come near the barrel. I'm on Vortex Tactical low rings.
-
With a .243 Win and that many rounds with those pressures, I'm surprised it's not shooting worse than it is. I imagine it's almost certainly the barrel. That caliber likes to burn em up.
Unfortunately, I don't have any information on barrels in Australia.
-
Wait, are we seriously going to debate using rational thought the decisions someone in some office made?
I don't think you're missing anything really all that obvious. They're just really really proud of their product. It's why I purchased a T3 Lite used at the gun shop and am building my own off of the action.
-
It's probably the adjustable stock as standard, along with the different muzzle threading and a manganese phosphate coating on the barrel. Or… and I'm spitballing here, it's so expensive for consumers because if they list it at that price they're able to have wiggle room to wrangle M/LE contracts.
-
I do have to admit, it's a lot more difficult to compare different models on the 2015 Tikka website. I prefer multiple tabs. It looks like the caliber choices between the two only meet on 308 win. CTR has 260 Rem, whereas the Tac has 223 Rem, and 300 Win Mag. Adjustable cheek piece is standard on the Tac, only an option on the CTR. The muzzle threading also appears to be different.
In my opinion it makes sense to replace the factory stock. Take into account that I need a 14.5 inch LOP and you can understand why.

Maybe you can spend the downtime formulating new CNC programs for awesome new gears?

Thanks for the update Jason.
When I spoke with Robert the other day he told me you weren't supposed to do any work for two weeks after your surgery. I applaud your dedication to us that you've defied the order and given us this information.
That said… Hurry up and get better so that you can get back to what you love! (Which coincidentally will also benefit the Tikka community.)
