Not for me, there's not. And (but), I do not shoot 3/4 oz. loads in any gauge but .410 and 28. I shoot 7/8 oz. in 20 gauge with the exception of my Fox Sterlingworth Ejector 20 which is regulated for 1 oz. loads, and that is all it gets fed. I only shoot 1 oz. in my 16s. 12s and 10s get to do the "heavy lifting".

However, recoil is not an issue for me unless it gets severe enough that it affects my ability to deliver a well aimed second shot quickly. And, I have found that to be more related to stock configurations and weight, than payload.

Another however, I keep all my loads as near 1150-1165 fps as possible. I have found zero benefit from higher velocity with the only exception being steel shot for waterfowl, which I rarely use anymore.

Looking forward to us maybe being able to shoot .410s some when you venture South this winter, Jeff.


May God bless America and those who defend her.

I tried using smaller gauge shotguns and went back to the 12ga and adjust my loads to what I want. I have sxs 12s as light as 5 lb 15 oz and I have loads as light as 11/16 oz for my 12s and more st a f my sxs have plastic or steel butt plates. I still have a couple 16s but they weight the same as my 12s and shoot the same weight loads.


After the first shot the rest are just noise.

What is the source of this? Is it empirical data? Are there any standard deviations offered with it?

It's simply a calculation Brent, not a measurement, so no SD
Lots of formula out there; this is an easy one for recoil velocity which as you know is not recoil force

IMHO felt recoil is impossible to quantitate - too many variables

So, this appears to leave only gun fit and balance as physical variables. Personal variables are another matter.

Obviously I was looking at the differences in the one ounce loads. Of course.Half a pound is trivial, but it suggests that perhaps the formula is curve fitted, and not a first principles formula. I will try to find time to look at the articles later, but right now, having fixed my truck, it's off to Iowa for the opener.

An attempt to quantify 'felt recoil'. The full text PDF can be requested
https://www.researchgate.net/publication/223811001_Measuring_felt_recoil_of_sporting_arms

Those with migraine headaches and a history of concussions and traumatic brain injuries are IMHO much more sensitive to recoil.

never heard anybody refer to a 12 or 16 as a magic wand...

That's because you do not listen well.

I have a pile of light 12s that I've gathered over the past few months to use as prize guns at our RGS Chapter events. If I were struggling with recoil issues, that's the direction I'd go.

My 16 (Poli) is 6 lbs, and it's no fun for 100 clays. I'd much rather shoot my 8 lb AyA Model 53. Horses for courses, IMO.

My daughter has been shooting with me off and on for a few years, and started out with a 6 lb. 20 gauge Superposed lightning...she's finally getting good enough that she's noticing the light gun with short barrels is costing her targets. I recently got her a 12 gauge Superposed Lightning with 28" barrels that tips the scales at 7.7 lbs...she can tell just by picking it up that it'll help. The added weight will help recoil too.
