when you flush a shot

Quite honestly, that depends on the size of the divot, the type of grass and dirt, the moisture levels, etc. And the shaft you're using.

I've felt it, but it's not common.

Off of a matt at the range when I am overswinging and I get it just right (pure) with my 8i. It goes about 160 (which I have no right to be hitting an 8i) and I'll get a definite feeling that the shaft is vibrating. Happens about once every other bucket. Probably means that the strike was exactly at the frequency of the shaft...the shaft was plucked like a guitar string. But not something that really matters to swing well.

I only feel that when I'm trying to hit a punch shot, and that's because the iron digs into the turf, which is generally pretty hard at my home courses. Either that or I feel it do that when I really blade it. If you don't want to spend $200 on C-Tapers, you can always go to the hardware store, buy a couple yards of adhesive window stripping, fold it around some fishing wire (for easy removal) and slide it into the shaft next time you regrip your irons. Helps minimize vibrations, or at least absorb some of them without dimishing the feel all that much.

If by "flushing it" the OP means when I bury my iron up to the hosel after impact (not something I try to do, but it happens), then yes I have experienced this.

When I hit one flush, pure, whatever, it actually feels a little like a fat shot except a fat shot goes about 30 yrds and a pure shot goes about 30 yrds farther than expected.

I only started feeling this consistently after re-reading The Impact Zone and finally understanding the aiming point concept, which I believe is called Impact Hand Location in TGM terms.

LOL, in a way, I actually am trying to bury the iron up to the hosel after impact, this doesn't actually happen but it seems to work well as a swing thought.

YMMV.

Sorry, I don't know the feeling.  The only time I ever feel vibrations, it's always a bad thing.  Severe toe hits rattle my hands and hurt my fingers like hell (especially if its cold) as if I got sawed off on an inside fastball.  And, also as mentioned above, if I dig my club into the turf too much, or if I hit a root or something in the ground I didn't know was there, are the only other times I feel vibrations. 

Im 5'10" 180 last time I stepped on a scale and my best sets this year are squat 360x5 deadlift 375x5. I hit 6i 185, 7i 175, 8i 165. I am playing snake eyes 685x irons with Project x 6.0 shafts 1/2" short of standard... I switched this year from a set of macgregor forged PCB irons with true temper stiff shafts... they were a good 3/4" longer then my current shafts. the new irons have a bit weaker face angle. I think the new shafts being a bit stiffer made the difference because I gained about 10 yards on each club when I made the switch. i'm hitting 9 iron now from the 150 stake rather then 8 iron.

As far as the vibration in the shaft I have never felt it on a pure shot, only when I lay the sod over it. A stiffer shaft may help you, but I would think you would see inconsistent ball flight if the shaft were too weak.
