Recoil is essentially the backward moving motion of your rifle, it is the reaction to the force created by the explosion which pushes out your bullet. Several things affect this:
1. amount of powder and weight of the bullet. More of each means stronger explosion and stronger forward push, which in turn means stronger backward force and more recoil. Solution - use lighter bullet and/or less powder (for example, subsonic 308). Solution 2, get a smaller caliber like (in order of descending recoil) 7mm08, 6.5 Creedmoor, 243, 223.
2. the weight of the rifle. The heavier the rifle, the less it moves when being pushed by the same amount of force. A 8kg rifle would in theory have 50% recoil of a 4kg rifle. People love super light rifles for easy carry. Your rifle is one such product that caters this market. Solution - get heavier rifle - longer and thicker barrel, wood or chassis stock, big scopes (most 5-25 are about 1kg, vs 3-9 are about 300g). etc.
3. length of the barrel. Recoil push does not happen until bullet leaves muzzle. Recoil is the backward push by the escaping gas, therefore the more that the gas expands inside the barrel the less the sudden push when it gets out, and the less recoil. Solution - get longer barrel. 28 inch should have less recoil than 24, which has less recoil than 20, which has less recoil than 16.
4. muzzle device. Muzzle brake controls the direction which the gas escapes, while suppressor controls the speed which the gas expands. They both help reduce recoil, but muzzle brake does a better job, at the cost of louder bang. Solution - get a good muzzle break.
Since you already have the gun, your cheapest solution is to use light or subsonic rounds, and add a muzzle device.
For your next rifle you should consider a thick and long barreled 223. cheap to shoot and you can enjoy shooting.
Add to this internal muzzle brakes, contained within the suppressor so you don't get the bother of the blast. @gundoc may be able to comment.

While much of this is accurate I'm not sure about point 3. Longer barrelled rifles experience less recoil simply because they are heavier. Recoil is Newton's Third Law of Motion - the 'action' of both the bullet and weight of the gases and unburnt powder moving forwards causes an equal and opposite 'reaction' moving backwards.
Although the sound quality is crap there's an interesting comparison between a suppressor and a T2 muzzle brake here. Conclusion: the muzzle brake on test makes a substantial difference to measured recoil whereas the suppressor makes very little difference. The recoil perceived with the suppressor may be less because of the reduced noise.

Many decades ago as a schoolboy I used to shoot 3, 6 and 900 yards at Tai Tapu with a brass butt plated .303 service rifle. Being all of an eight stone string bean my shoulder definitely felt it but thankfully I never developed a flinch. Good training or good luck, I don't know?

I have always wondered if this is doable.
In your normal suppressor, holes are uniform and non-directional. Gas evenly and progressively escape the holes as it moves from end of muzzle to the end of the can. If you add a muzzle brake inside the suppressor, you push gas backwards but then the gas is immediate met with the wall of the suppressor. I would think the suppressor will be blown up fast. unless you make it so the suppressor can extends out in a "A" shape. but i have never seen such a device.
It would seem that you are sort of correct, and I was not.
I looked this up and what others report is that the longer the barrel the faster the bullet therefore MORE recoil, but the extra weight on the gun cancels out that, resulting in more or less the same overall recoil. That is quite interesting.
What is also interesting is that people "feel" more recoil when the gun is louder. Shorter barrel definitely results in a louder bang, which is probably why i always felt shorter barrels produce more recoil. It seems that shorter barrel only produces more felt recoil, not actual recoil.
Directional brake
Will reduce recoil far more than any suppressor
If you hand load, load lighter pills
Suppressed 308s shoot like pusy cats so a braked one must be far better
Dont waste your time chasing every last fps, it doesnt matter in the real world, it wont make a difference, all it will do is cause head aches and frustrations. And dont listen to silly old cunts
It would work on the principle that recoil starts from ignition, from when the gases and the bullet start moving forward in the barrel (i.e. not just on venting at the muzzle). The gases being internally momentarily vented backwards at their highest speed will at that moment cause a reduction in recoil. The can is designed to safely contain what it does.
Once they slow down and go in all directions inside the suppressor they are directionless overall, and thus no longer contribute or detract from recoil - until venting out the front of the suppressor at which point they again produce some recoil but at that stage they have lost much of their velocity (energy). So I agree it's a bit academic whether the internal brake does much. What IS happening with a suppressor is that gases lose velocity/energy, so that when they exit from the front of the suppressor they may have similar volume and mass but much less velocity/energy. It also means the suppressor reduces recoil by other mechanisms than merely adding inertial mass to the rifle system.
I had a discussion with, I think it was @gundoc, and he insisted the internal brake did make a difference. If we view gases traveling forwards as increasing recoil, gases traveling backwards decreasing recoil, and gases traveling in mixed directions as being net zero for recoil, that makes sense.

My experience...... I never used to have any problems with recoil/muzzle blast. Then a few years ago i had a couple of strokes. After 20-odd years of driving mostly American trucks, my hearing was pretty much fucked, so muzzle blast was a non-issue, though I did use muffs when practicing. Then, a few months ago, my brother came out here with his Ruger Model 77 mark II in .300WM With the heavy Laminate stock and a muzzle brake, to sight it in. It's a fucking canon. Anyway after firing 3 rounds I knew I had developed not just a flinch, but a veritable cringe. The sonic boom, seemed to send breakers through my injured brain. I couldn't/wouldn't take another shot that day, and the headache was a bastard. I've been shooting only my .22LR since then and I KNOW I'm going to have to work on this fucking flinch when I can steel myself to shoot my baby (.270wsm) again. The rifle (x-bolt) is something I will never get rid of, but it's gonna take some work to sort myself, And I've loaded some rounds that I need to validate. It's something I look forward to with some trepidation, instead of joy. So thanks, fellas for all the advice regarding recoil management. I'll be reading this thread often in the near future.
Used to be a fine wine - now I'm vinegar.
Recoil is directly proportional to the weight of the firearm versus the weight and velocity of the ejecta (powder and bullet). The effect of recoil can be mitigated by the fit of the firearm to the user, shooting stance, and add-on items such as recoil pad, muzzle brake, and suppressor. Assuming the fit and stance are correct then the greatest reduction effect will be from a properly designed suppressor and a good recoil pad. A proper suppressor design will incorporate an effective muzzle brake coupled with an efficient baffle design. Over-barrel suppressors use the rear chamber to reduce gas pressure exhausted from the brake while the baffle design should consist of a series of shaped chambers that use the front surface of each chamber to absorb some of the forward force of the ejecting gases, thus tending to exert a counter-recoil force. The sound suppression also makes things a lot more pleasant for the shooter and tends to reducing flinching (refer to 'stance' mentioned earlier). A good suppressor is, overall, more effective than a good muzzle brake.
Thanks everyone for advise. The discussion pretty much cover everything possible to manage recoil. Freaking awesome, the best forum to date. Cheers!
@sheep...have you read that article yet????
did it make sence/compute with you????
