He did write about RPMs but was only talking low 200,000s. These were 45-50 grain .224 bullets so they wouldn’t be spinning all that high by today’s standards. He also gave some credence to the hydrostatic shock theory which I think was probably really CNS disruption by fragments. They had no way of measuring velocity down range so there was some theorizing that the bullets had slowed to .22LR speeds but maintained their spin which compensated for low velocity.

I think some of the “why” conclusions were off but the observations (results) were poignant. He talks about killing 600lb animals reliably at 600 yards with 50 grain .22 caliber bullets.
I’ll have to pull mine out and reread it, thanks.

Heading out tomorrow to see how the Tikka .223 likes the 77 TMK factory black hills ammo. Will post the results in the Tikka 10 round group thread.
Just realized I never posted up these results from back in January... I'll just show it here.

I had put a new stock (Stockys VG2), new scope (Maven RS1.2), and new rings (UM Tikka Rings) onto my Tikka .223 20" factory barrel 8 Twist rifle. It had been sighted in and shot with around 1,000 rounds of Hornady factory 73 ELDM with that setup with good results.

I was convinced by the data and results from @Formidilosus, @PNWGATOR , and a few others in this thread to switch over to the 77 grain TMK as I'd like to deer hunt with this rifle this year. I bought a bunch of factory black hills ammo using the aforementioned bullet.

First shot as a baseline at 100 yards (interesting deviation from the 73 ELDM). Using the Maven MIL reticle as a ruler as per @Formidilosus sight in method I moved right .4 MIL and took a second shot. I moved it back left .1 MIL and didn't touch it again.

The next 48 shots were in the left square, scope on 8-10ish power, only time between shots was to reload magazines. This was shooting from a folding plastic table with short spartan bipod up front and puffy jacket wadded up as rear rest. Calm winds, 55 degrees.

I have since shot around 1,500 rounds with this rifle setup and ammo, and haven't had anything but excellent results so far.

Am I understanding your post correctly that you're saying the left square has 48 (forty-eight) shots in that hole?

Please reconsider and start at the start.

Your ‘good deal’ isn’t.
Come again? I got it well under the cost of a Tikka. It has shot nothing but sub moa groups so far and came with a 16.5" threaded barrel. I get that Remington has had its issues, but they seem to have worked them out. Its as good a shooting factory rifle as my Tikka 6.5 which is seriously good.
