New TMK announced

How long does Sierra usually take to release their official load data for new projectiles? I figure I can probably use a 107 HPBT/SMK or similar to get started but as a brand new reloader seeing the actual projectile I'm loading listed in the load data gives me a little confidence boost. I got some 107 TMK's for my wife's rifle but haven't started on that one yet figuring they'd be releasing some data at some point but seem to be dragging their feet on that. If it's gonna be a while I'll just get started but if it's right around the corner I can wait a bit.

my 6 dasher: H4350 34.1gr 108 eldm @ 2.367 COAL (~.010 off jam) = 2870; 107 TMK @ 2.46 (~.010 off jam) 2846.
108 eldm @ 2.367 32gr varget = 2918; 32gr varget 107 TMK @ 2.46 = 2865
different days with varget, but similar temps i think.
 
Loaded up 50 107's in new Alpha Dasher brass last night, hope to push them through my brand spanking new barrel to do some speed up this weekend before load dev. Loaded them with a very mild 29.5 gr Varget, thinking after that I'll do a bunch of 5 round groups at 0.5gr increments. Will need to wring some speed out of this one, Ladasha only has an 18" barrel and is waiting on either a 2-12 NX6 or 3-18 Rokscope to trim her top end up a bit lol.
