Proper eye relief distance for No. 32 Mk. IV scope?

[CINDERS]

Had a chap pay no attention or heed my advice about eye relief whilst shooting my scoped 336 Marlin 444 S micro groove with hot reloads, if you've fired that rifle in that caliber then you know they are fairly lively.
The retort I got from him was "fired lots of these types." what ever dude. "Bang" lots'a claret thank fully none on the bluing trip to the hospital for him to receive 4 stitches. I only got bruised once by it that was enough.........

Newcastle, hold the rifle not shouldered with the finger on the trigger. The space between the butt plate and your upper arm at the elbow will tell you how much you need to add to the butt to shoulder it properly. Not entirely accurate but tells you why some rifles hit your shooting glasses and others don't.

With a properly fitted LE you must be able to shoot and work the bolt without moving your face/cheek from the butt.

"...Paratroopers dropped through a hole in the floor..." That'd be Brit and Commonwealth Paras. Our(my South) Southern cousins went out the side.
Like Peter says, the correct eye relief is the one that gives you the whole sight picture. Ain't nothing gentle about the reminder though. It's called 'Weatherby Eyebrow' in the real world.
"...the difference that a longer butt would make...." Puts your face farther from the rear ocular. You kind of have to experience a too shot butt stock to appreciate having the right one. On your LE's look at the bottom of the wrist of the butt just aft of the trigger guard. Your choices are S, N, L and XL. 'N' being 'normal'. I think there was a "Bantam" length too. A sort of extra short. Having the correct LOP makes a huge difference. Even with iron sights.
"...between the butt plate and your upper arm at the elbow..." LOP is actually field expedient measured by putting the butt in your elbow and grasping the rifle as if you're shooting. If you can't reach the trigger or it's too close to put your finger on, the LOP is bad. Same thing can be done with a yard stick to find out what your LOP is. Where your finger comes on the yard stick is really close. You can measure LOP by shouldering the yard stick like a rifle. Where your finger come is your LOP.

The No.4 rifle had four different sized buttstocks available. Each length increases by 1/2". They are; B-Bantam, S-Short, N-Normal and L-Long. The marking is just forward of the buttplate on the heel, (top), of the buttstock. Bantam stocks were only made in Canada as far as I know. There were no XL-Extra Long buttstocks made for the No.4 rifle.

You're talking about FN C1s now.

You could always use a slip on recoil pad may look nerdy to some but negates allot of in Peter's words Faffing about fitting up a replacement butt stock that's what I would go with.

And it will keep the rifle 'Original'

I use one of those slip on pads, works every time.

I now swear by the rubber bolt on pads - butt plate screws go through it. It protects the butt plate, increases Lop by 1.5 inches, has better grip in the shoulder and reduces felt recoil. Saved me changing all my butts from normal to the elusive Longs.
