I have a Tikka 22" barrel with an 8 twist and I bought these bullets a while ago. I'm looking for a place to start, preferably with StaBall 6.5. Could DrMike or one of you fine gentlemen with Quickload please run that combo. If StaBall is not in QL maybe a run with a variety of powders. Thanks in advance.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 65000 psi, or 448 MPa
or a maximum loading ratio or filling of 100 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

2 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Could DrMike or one of you fine gentlemen with Quickload please run that combo. If StaBall is not in QL maybe a run with a variety of powders. Thanks in advance.
if StaBall doesn't give you what you're looking for, RL-17 worked very well in my fast twist 22-250 with the 75 ELD-M. One of the few rifles I truly regret selling
 
Thank you very much DrMike, I greatly appreciate it!

Hunter, I have quite a bit of RL17, I might give that a try as well, thanks!

The rifle is definitely a shooter, I have 2 sub MOA loads already, 50g BTLF over Varget and 64g Hammers over StaBall.

I’d say you’re golden.

I‘d bet a dollar or two that 17 or SB6.5 will show you the good.

I LOVE that 77 TMK. Probably my favorite 224 bullet. Accurate as all get out and just works on anything.

Thanks, Scotty! I shot this little Tikka this past weekend with the 50g BTLF and the 64g Hammers for groups at 100 yards. The 3 BTs were at 1/2" and the 3 Hammers all in the same hole and only an inch higher than the BTs. Now I need to stretch them out and see how they do. Can't wait to see how these 77g TMKs do.

That's typical Tikka performance. Silly things just shoot!

I'd bet you'll do great with the 77 TMK's.
 
Well I tried StaBall and RL17, and StaBall matched up with QL almost perfectly, thanks DrMike, but RL17 gave better velocity and accuracy. Thanks hunter24605. I had 2 in 1 out yesterday at just over 3200 fps, so I seated them a little deeper and just shot a nice 1/2" triangle at 100. Now I need to stretch it out to confirm. Got to love these Tikka's.
