Ok now you guys that visit this site alot must know about big bore kick....I shot my 12 ga benelli with 3.5" max loads of 2-1/4oz lead....off a sand bag to sight in for turkey season....there is no recoil lightening gas pistons in this gun....I am a big guy and I dont flinch, but the recoil is brutal...the shoulder and the check bone are plenty sore after 10 rounds

what compares in the rifle calibers to that load in terms of recoil?.....thanks in advance...bob

Need to know velocity of your load and the weight of the shotgun and powder weight.

Let me guess:

2.5 oz. = 1093.75 grains
50 grains powder (I don't know drams)
1250 fps velocity
10 pound shotgun

23.25 fps recoil velocity (ouch)
195 ft/lbs recoil

So shoot 2 3/4 or 3" shell and don't beat your self to death with those 3 1/2" shells -there is no big advantage to justify the 3 1/2 " shell use on turkey's , you should be able to get them within 40yds. I find that 3" are plenty and 2 3/4" shells work just fine.

Huh, I am not into shotguns but I was looking at some other calcs.

That is roughly (ballpark) in the area of a .600 Nitro Express pushing 2,300 fps in an 18 pound gun.

roger...the load is a 2-1/4oz and the gun only weighs about 8lbs max....its a benelli SBE..they arent very heavy...the velocity is probably in the neighborhood of your guess...maybe more but not less

gunnut, I have the gun and its chambered for the longer shells...its good to have a large margin of eror while turkey hunting...you end up shooting lots of branches and saplings...plus sometimes the bird hangs up...patterns are tested at 40 yards so I thought that would be my max....and I may make a slight error in yardage while hunting....so the more pellets the better. The kick is never noticed while hunting...like most guns...but when you lean over the gun and try to hold that thing steady knowing full well you are gonna get hammered...it is VERY noticeable. they made 3" as an IMPROVEMENT over the 2-3/4" loads and they made the 3.5 as an IMPROVEMENT over the 3"....I will most likely shoot my birds at les than 40 yards....with the super tech choke tubes and the loads this gun will shoot, a guy COULD kill turkeys with head shots at 60 yards!!!!!!bob

It is almost impossible to compare "felt recoil" between a shotgun and a rifle IMO...

well according to the recoil formula assuming...30 grains of powder in the load, and a wad that weghs 45 grains itself(long) and only 1200fps and pushing 2-1/4 oz of shot

the recoil comes to 73.8 lbs

what do the big bores produce with hutning loads?

I have a 7mag in a remington 700 and have shot it and it NEVER compared to the 3" slugs I used to shoot out of a mossberg 500 pump gun...sighting the scoped shotgun in was always a brutal experience!!!!!bob

I've got a 10ga double. I picked up some 1 3/4oz slugs in 3 1/2" shells. The gun is heavy, don't know the weight. what would this compare to roughly in a big bore rifle? What if I shot both barrels at the same time? 3 1/2" no2's 2oz seemed pleasant to shoot. I guess I could weigh the gun and clock the slugs.
the biggest rifle I've shot so far is a 375 H&H.

LAR45... if you want to make the 10ga kick more get some turkey loads. I shoot a 10ga single and they 10ga turky loads kick much more than the 10ga slugs. (they have less lead!)

222blr, I have shot a rig like yours and can honestly say that the recoil is in line with a hot loaded 416 Rigby i.e. a 416 Weatherby magnum. It was less brutal though, than the recoil I encountered shooting an 8 pound 458 Winchester magnum. If/when you get comfortable shooting that load you should have NO big problems shooting a big bore rifle.

About like a narrow, steel Butt, 5 lb Marlin with Hot 45/70's. Painfull, Very very painfull!-Rob

222blr--The shotgun being light at 8 lbs for that load and velocity, needs
2 lbs in the butt, and should still point good.
Maybe even better balance.Will help bench shooting
quit a bit.If you can set up tall bench or something similiar, it helps a lot also.That's how we tested my wildcat with 110 ft lbs of recoil.Ed.

I don't think recoil from a shotgun can be compared to big rifles either.

600gn brennekes from a cheap boito double(7 lbs?) kicked less than 375 H&H factory to me.
1 7/8oz BB loads from same shotgun kicked worse-but still not in the ballpark of a fast 458 for example.

Lars,
I pulled both barrels from the light double with the 1 7/8 oz BB loads.
4 oz of shot and wad from that light peice should have been recoiling up to 150ftlbs on paper.
Still I didn't find it is bad as a bigbore clocking say 80-90ftlbs on paper.

Might be because the delay in triggers was spreading the shots instead of multipying together precisely?- Or because I was expecting to get knocked over maybe.

Karl.

Big, strong, heavy guys have more trouble with recoil than smaller, lighter people... inertia, you know!!
