Gun fitting and Testing for point of impact

Testing for point of impact

I have a new gun and last week a got a trial of a different gun a loan from my rfd , I have been shooting quite well with my 28" fixed choke Miroku 6000

But it has it limitations so i opted for a 30" multi

Now with the loan gun was fine on anything not low down any thing crossing low or rabbits and i missed and tbh i had a job finding them

However this gun had different stock dimensions than my Miroku 6000 my new gun is very much the same and so i hope its gona put the shot in the same place

now ive been reading up on gun fit and found this

 

Using a pattern plate to test Testing for point of impact

Put in your full

choke (do all testing from the same barrel of your O/U) and stand back

about 30 yards. You want a heavy, dense strike on the plate.

 

Assuming that the plate has a single central aiming point, start

with your gun in the normal gun down position and the muzzle right on

the aiming point. Raise the gun and fire in one smooth move. Do not

repaint the plate yet. Load again and this time start your muzzle slightly

to the left of the plate. Mount and fire as you swing through the aiming

point from the left. Now do it from the right, top and bottom of the

plate. The idea is to average all your normal mounting moves.

 

The plate will now have five overlapping strikes on it. It will be

apparent if your gun shoots to point of aim. Repaint the plate and

perform this entire exercise enough times to get consistent results.

Always aim for the center, but do not try to "correct" if the gun is

shooting a bit off.

 

If your five shot cloud centers the aiming point or is very slightly

high, go have a beer. You are done. You are also very lucky. If your

point of impact is too high, you will need to lower your stock. If too

low, raise it. If too much to the right, you need cast on (assuming you

are a righty). If too much to the left, you need cast off

 

So my ground owner has said its fine to pattern my gun @ the ground should i do as above to test the the gun fit

the shop owner visibly checked my mount / fit and said its fine but i would like to know where i am actually shooting

short of using tracer rounds that a well known mail order cartridge company are offering is there any other way to find if im putting the shot where i think i am !!

Yehh i know if the clay breaks then i am But am i ?? i could be compensating and there lies a issue

[T.C.]

Gun fit is a complicated issue and most would advise enlisting the help of an expert gun fitter to avoid expensive mistakes if you change your stock.

i just use a laser bore cartridge thingy, saved all that painting and stuff

Yehh i prob going to get this gun professionally fitted if i find i get on with it

I was just looking to see if its way off im not about to take a big rasp to my new gun lol

As for the laser thing good point but tbh i was looking @ just knocking up a pattern plate then i can shoot directly @ it and additional swing across and fire

with a plate im going to be able to see if im putting the shot where i think i am

it should show if im high low or whatever with a laser thats going to be hard finding a 30 yard range and reliable spotter to see if the dot hits the mark when i pull the trigger

Good idea tho

As luck would have it my pal drives for a fiber board manufactures and hes getting me some nice big pre cut boards to shoot at and i have a plotter big enough to plot some nice targets on to this board so it will look like a proper job

Saves me taping flattened boxes out lol

not really, go out at dusk when its getting dark, thats what i did on tuesday and found out that i had raised the stock a bit too much, so my shots were going high at 25 yards :good

for point of impact it is useless shooting at 30 yds,this will tel you what pattern you are getting and roughly where you are shooting. to find out if your gun is shooting where you are looking you should shoot at a point about 10 yds away, aim at this point as you would a rifle.
