Questions on #5 rifle micrometer sight and #5's muzzle velocity

I was wondering about how much mv loss the #5 rifle has compared to the same ammo in a #4. One older book I have lists the #5's mv at 2000 fps. A general rule of thumb of 50fps loss per inch, would put it (taking from 2400fps) at maybe 2110fps, just a guess. Was wondering if anyone has chronographed mv of both a #5 and #4 with the same Mk 7 ball ammo or equivalent handloads.

Are the micrometer sights graduated for one click=one MOA?

Is the zero for the battlesight on the #5 sight supposed to be the same as for the battlesight on the #4? Reason I ask, is that the #5's battlesight is set considerably lower towards the axis pin than the #4 sight. It shows a whole lot of the elevation knob within the apecture's picture, compared to the #4 sight.

What are people's various experiences as to the...call it "honesty"... of the graduations of the micrometer rear sight with ball ammo? I trust the adjustments of the M1/M14 sights and have learned how to do backlash compensation for them. Much more elevation backlash seems to exist with the Enfield rear sight. Once backlash compensating is done, is the elevation scale pretty honest for both #5 and #4 rear sights?

Last question: Looking around for bullets, it seems as if the best buy on bullets from a company that actually has them, it to buy Sierra Match Kings in quantity (Hornady FMJs seem to be out of stock). But I've seen Hornady hunting bullets deform under recoil while in the mag. Has anybody used SMKs in an Enfileld mag and could comment on what damage if any is done to the bullet tips in the mag?

I realize that the best answers come from range time. The questions have been answered already at some time in the past, and I'm trying to save on ammo and components by picking other people's brains. Thanks for your help.

Comparing the Enfield micrometer sight to the M1 sight is like apples to oranges. Each increment on the Enfield MkI sight is about 25 yards. As you know there is no windage, so the squaddies were taught to "aim off" or use "Kentucky windage" as some people in the USA call it.
As far as the No.5 goes I can not comment there, no experience. The rifles were zeroed with standard MkVII ball ammo with the rear sight set at 200 yards. The elevation was fine tuned by changing the height of the front sight.. I am sure somene will be along with all the details shortly if not already, I type real slow.

PF, The clicks on the backsight aren't in MOA steps, tho' at close range can be fairly close. I wrote some notes at 300 yards and I'm still looking for them, but will post if and when I find them. (My older daughter was a bit too thorough in Hurricane Rita prep.) IIRC, the No.5 took about five more clicks than the No.4 going from 100 to 300 yards, but the rifles really aren't directly comparable (pet competition No.4 vs. a VG No.5). I've found the backsight settings to be reliable if using the same ammo. Generally I'll mark my range with a pencil on the side of the backsight instead of hunting for a specific foresight block height.

Not really answering your questions, but hope it helps.

The 50-75 fps/inch rule is a fairly good .30 cal. average of what to expect, but in no way is set in stone as two similar rifles shooting the same ammo can differ that much.

I'm still shooting HXP. I hope the scare is over soon.
