.223 for bear, mountain goat, deer, elk, and moose.

In case it is helpful, I have been putting together a spreadsheet of approximate speeds, group sizes, etc. for various factory 223 rounds. Take the group size with a huge grain of salt. All shot very well, and only for a few did I measure with great precision. This should all be regarded as indicative.

All shots were taken with two factory 20” Tikkas (the “Ranahan” model, with iron sights removed. A picture of the two rifles in question is attached. Ignore the wonky mount on the one in the KRG. That scope doesn’t live on that particular rifle.

Speeds were chronographed with the Garmin. Elevation is just above sea level.

I plan to add to this over time.

(Strangely, the Hornady Superformance 223 loaded with 53 Vmax would not fire, despite the firing pin creating significant indentations in the primers. The same rounds would fire just fine in a friend’s AR. I’ll try another box at some point.)

All the best.

If anyone is looking for XBR, they have a large supply at scheels in Billings. $60/pound or $42/pound if you buy an 8-pound jug…

There’s 10 shots in this group. I wanted to get some solid velocity numbers for my boys gun. I shot 5 and he shot 5. He hit 3 in the bullseye and the 2 in the orange. All from about 60 yards. Not bad for a 5 1/2 year old.

16” tikka with a wolf hunter averaged 2630 for the AAC 75bthp.
