Torquing from recoil am I imagining this?

[OIF/OEF]

I throated my 300WSM barrel to shoot heavier bullets. I loaded up some average not stout 300 WSM loads with 210 grain Bergers and noticed the extra recoil of course but I swear the rifle torqued when I fired. I was shooting in cheapo sandbags and not sure if that's it but I shot maybe 8 shots and every shot the rifle felt like it ended up twisting slightly. If this is in my head or due to crappy gear I apologize for posting and wasting the space.

Torque reaction when firing is normal.

I have a Kimber Montana in 325 wsm and when firing from sitting/sling the pistol twists around at least 30 deg..
Must be a counter-directional muzzle brake out there some where...

i notice this esp if my bipod is loose.. my acd is level, shoot and the gun has rotated to the left (counterclockwise). i believe a right hand twist will recoil/rotate counter clockwise and expect a left hand twist to do the opposite. the right twist bullet is torquing the barrel ever so slightly in a clodkwise rotation and when it exits the muzzle the barrel "snaps back" in the counterclockwise direction. sounds logical, but i could be wrong...again.

Probably a product of your grip/setup, try a free recoil style.. What load did you use for the 210 Berger?

Torque is real. Several BR stocks now are made with the barrel and action offset to one side to counter the effects of torque.

 

[Preacher]

Just another reason why some stocks have 5" and wider fore ends....

You should shoot a 45-70 with a 535 grain pill for giggles. That big tall vernier sight will move about sixty degrees left if you're not holding on.

This is one of the primary reasons that 30BR shooters use very slow twist barrels on their rifles.

To answer your question, yes the rifle will torque. It can be mitigated with corrected positions, bags, and techniques.

Some questions so we can help.

Were you shooting prone or on a bench?
What kind of rifle ie: hunting, benchrest, f-class?
What stock?
What kind of bag on front and rear?
How much shoulder, cheek, and hand contact?

The 300 WSM does have a lot of Torque, both my L.G. have NBR. Stocks so I hold on to the Forend when I shoot, I can't shoot free recoil. I'm Old School. This year I'm going to the 230 OTM's but when I shot them I couldn't tell any difference between the 210 VLD's and 230's. But when I'm shooting all I think about is the squeeze nothing else.

I believe that torqueing is more of a problem in bench shooting. Upsetting the rifle, in the front and rear bag, delays follow up shots and tracking.

SSS Dog Tracker stock has worked quite well for me regarding torque.

 

[GerryM]

Yes it's normal.
As someone has already pointed out if you want to reduce it it requires a slower twist, then you limit bullet weight to some degree.

I remember a long, LONG while back that someone with a math background crunched the numbers on torquing and "proved" that it wasn't as big a deal as people were making out. it may have not even been this fourm...it may have been over at BR Central.

Now, this is NOT ME saying this, and I may have " mis-remembered" (to take a phrase from the Obama White House) a bit!!!

I shoot a 16.5lbs 300wsm and it is apparent when I shoot 210 bergers also. Funny thing is, my Cooper in 22lr shot free recoil has the most noticeable torqueing(is that a word?) of any of the rifles I own. It's the only one I shoot free recoil though and only as an experiment.

My 300WM gives a pretty good twist when shooting 230's with a stout charge of H1000.

Gunsmith friend of mine built a 308 for one of his customers using an A4 Mickey stock. Shooting 168's with the 10 twist Douglas the twist/torque was way more noticeable than my 11 twist Rock in one of the return M40 stocks. I think more noticeable not because of the twist difference but because of the stock design. The A4 forearm sets much higher and the center of gravity or whatever changes or at least makes it harder to hold upon firing with just a one hand hold on grip. With all of the time behind mine perhaps it was more noticeable. I have my 6.5x47L in an A2 and notice torque with it more also even shooting the 123's. Always thought the A4 was a poor choice for the M40A3's and A5's because of the forend design but then again those shooting them are better men then myself so maybe not a problem for someone not a wusse like me!

Friend in MT had/has a 7 short mag in IIRC an A5 and with 162's he has a hard time keeping both bipod legs on the bench because of the torque effect, so it does/can change technique etc.

How does this affect groupings if any? Are you guys saying this twist your rifle to one side? I'm confused.

Wonder if you cut a right hand twist for half the length of the barrel and a left hand twist for the other half - would it overcome that torque problem : (Just kidding guys)
