5R rifling trivia question

[Mark M.]

Here is the story, from one extreme to the other, as I understand it....bureaucrats were running around in circles in Washington since 1947 trying to figure out what made Russian rifles shoot so much better than ours and why we were so far behind in the "shoot so well" area....on Dec. 24th 1979 the Russians invaded Afghanistan. Realizing we had just seven more days to get our hands on a Russian rifle {this all happened in the 70's remember} SOCOM sent some operators in to steal guns, most of which got drunk and captured. One managed to get a rifle and 2:00am in the morning the Sec. of Defense woke up Jimmy Carter to ask "quick you peanut eating idiot, what do we do???" Ole' Jimmy orders a black helicopter to immediately take the gun to Boots Obermeyer to see if he, being our last chance and only hope, can "figure it out".....now ole' Boot's is not one to miss an opportunity and he gives us the third costliest gimmick in the shooting world, 5R rifling. The first two being the Colt Python and the Co-ax press. And the rest is history as they say......
The other end of that extreme is that the Russians for either lack of money or lack of resources use mild steel for bullet jackets. This quickly wore the drive side corner off the rifling, which by the way was never 5 groove in the AK-47. It uses 4 groove RH 1-in-9.25t. Russian geniuses at the time decided to make the corner rounded and hard chrome the bore, actually pretty smart. This allowed the cost effective and battlefield disposable AK's to last long enough to be useful.
Somewhere in the middle of all this is the truth. I have never seen it published what year the Russians adapted the style rifling. I have also never seen it definitively published exactly what the R stands for...Russian, radiused, ramped, rounded??? It appears that the Russians did it for different reasons than Boots. He did it to make money and certainly has, the Russkies did it to make the barrel last. In any case, Boots or Russian, ramped or radiused, 5R rifling does absolutely zero over any other kind of rifling that can be positively measured and proven. Believe what you want.

Can't wait for the movie to come out...

Cant you just see it now...they get Sean Connery to play Boots, in a lab coat and electron scanning microscope in his back yard.......Ed Harris is the govt moron that brings him the gun and says {with crap running down both legs} "Boots, you gotta tell us why this AK shoots 8" groups at 100 yards all day long if the russkie does his part!!! The fate of our nation rests on you!!! and Connery says, "I was figurrrrrrrrrrrring out rrrrrifling when you werrrrrrrrrre at yourrrrrrrrrrrr motherrrrrrrrrrrs teat boy!!!!!!"
Instant Oscar!!!!!!

Movie would be better with Chuck Norris and Charles Bronson in it as well ....
I guess the later one is not possible though.

Actually the "slant groove" "5R" Rifling has been around since the Civil war when it was used in Blakely (I think) artillery barrels. It was also used in some match rifles in the 1870's. https://www.go2gbo.com/forums/88-bl...d-cannon-sleeves-new-projectile-photo-13.html

I believe it was Bartlein that made them because their customers asked for them, but could document any advantages.
If it is on the equipment list, people jump on it.

While pointless, this was the most entertaining thing I have read in a great long while, thanks to @msinc

Aside from that, I used to think that Bobby Boucher’s momma invented 5R rifling because alligators are the debbil, but I stand corrected.

Thank you sir,and it was very kind of you to say so.....I felt it was my obligation to write something at least entertaining, given some of the stuff that's been posted on this forum in the last couple days...one guy is getting recommended to use 175 grain bullets in his 1-in-14 twist barrel...another is chambering his rifle to match the handful of undersize brass he has acquired!!!! The best one is getting 3200 fps out of a 16" barreled 308 with 180 grain slugs and the reason an AR shoots 1 1/2" groups is because the gas tube is bent. Good god yall!!!
Actually, it was Mr. Boucher's mammy that invented 5R, you were correct after all!!

Movie would be better with Chuck Norris and Charles Bronson in it as well ....

Yeah, but the libtard democrats that run Hollywood these days would have them both falling in love and getting married in the end...I don't know if I could take that!!!
Pee Wee Herman would play their young chicken assistant.

Edit: how do I know all this??? Well since it's just about all nothing but passed down hog schitt I don't. But, one thing I do know and know well, I was involved with the testing of the U.S. Army gunshot detection system..."Boomerang", et al. We tested every threat weapon out there at Yuma proving ground and I can tell you from personal, "been there done that" knowledge that there is nothing the Russians have I would consider "shoots so well".[/QUOTE]

I'd be willing to bet that the Russian rifles shot better than a 700 5R 308 Win Mil Spec I once owned.

After reading this thread, I've had a mini-brainstorm.
Someone needs to build a rifle with a 5R barrel chambered in the new 7.6 creedmoor ASAP. E.

Phideoux, gather up the wood and fire up the forges we got a job to do..

Wow... new “magic” calibers, rifling with a great story, scopes that can be commanded via voice, dogs that build forge fires... gotta love these threads, wonder what’s next?
