I finally got around to working up some loads for the 6.5 Creed Tikka. It seemed to like H4350 loads of 42.4 and 43.2. I did not see any over pressure signs on the 43.2 and wondering if I should try 43.1, 43.2 and 43.3, thoughts?

The pic of the cases shows the 43.2 (top) and 43.0, anything alarming on the primers?

Tim, 42.4 is exactly the same charge my 6.5 Creedmoor and a friend's 6.5 Creedmoor shot. After having done a 500 yard ladder test, then group shooting it at 500. Group shooting at 100 yards is tougher to find what the rifle wants.

42.4 seems to be "the" charge for the 6.5 CM and a 140 gr. When I switched lots, I had to bump it up to 42.8 gr, so you are in the sweet spot at 42.4. But if you want to retest, shoot the 42.4 and the 43.2 at 300 yards or more.

Thanks Jason, that is what I plan to do and then will begin playing with seating depths, currently .015 off the lands.

Buzz, this is the rifle I'll shoot at Jason's competition. I'm playing catch-up with all you accomplished shooters!

I shoot 42.3 in my Creedmoor with a 140 AMAX, so I think right in there is the zone. I can actually run up to 42.5 in the winter pretty easy, but that is too hot shooting fast and heavy in the summer. The rifle will handle it, but it starts loosening up primer pockets to fast on that soft Hornady brass.

Nice shooting, I would want to try between 43 and 43.2, if the velocity was higher than the others.

Unfortunately, I did not use a chrono (on wait list for Lab Radar unit) so I can't use SD or ES to decide on the load. 43.2 seems like a hot load from what I've read so wondering if I should just stick with the 42.4 for now and experiment with seating depths (shooting at 300 and/or 500) or if I should load up corresponding 43.2 and 42.4 loads with differing depths and compare.

Any thoughts on this? No pressure signs on cases or sticking bolt on any of the loads.

Also, below is my data and, in addition to 5 shot group size, I've also measured approximate group center from target (down and right in all these cases). I believe there are programs that do this but wondering if any others use this technique?

Buzz, I did not measure OAL at the tip but did with the Hornady OAL gauge with the 25 caliber insert (did not have the .264) so it will not mean much to anyone. I will provide on the next load... after Jason's competition. grin

Buzz, .015 off the lands as measured by the Hornady OAL gauge. I plan to try a few above and below at 300 or 500 to see if there is any measurable difference.

Is that 4+1 or 3+2 on the 42.1 group? I'd be tempted to shoot more at that charge as well. I never did have good luck running higher charges and keeping primer pockets on creed brass on any of mine. Nice freaking shooting too!

Am I crazy or is 43.0gr the best load? There's almost 0 vertical stringing in that group

Plenty of horizontal stringing, though.

Tim proved his rifle is shooting well, and he has good form, and good trigger control with the other groups.
