Was asked today what was the recommended distance from shooter to 30 inch circle target ,had a search on PW and it varies between 15 yds to 40 yds ,checked in my books and the the only reference was in shotgun and cartridges for game and clays at 40 yards, the question is from a guy that just shoots pigeon,always used 25 yards myself but thought i would ask the PW members their opinion.

In case it is useful to you I shoot all gun/cartridge combinations at 16 yards to check point of impact of pattern centre and 40 yards for quality.

+1.

Makes sense. I'd bet next week's pension if anyone were to properly pattern a combination at 20 yards and then, again properly, check that same combination at 40 yards they'd find that the latter result was more open the the former would indicate. Other than counting the pellets in the 30" circle to determine the degree of choke, it makes sense to also count those in the inner 20" one as well. Once any degree of choke is introduced, the pattern density in the centre will be enhanced and if you choose a combination which gives a sufficient pellet strike on average to suit your needs it will never be met across the full 30" and rarely, if ever, will it exceed 25".

I think too much emphasis is put on gun chokes, I have shot guns with all types of choke and personally not noticed any difference shooting birds at 25 or 40 yards and even 65 yards with 1/4 choke or full choke.

Things that do make a difference are gun/cartridge combination and the all important fit of the gun.

With a reservation of the highlighted phrase, a good post. I say reservation, as there's no mention of what is shot with what at the quoted distance and 1/4 choke.

These are the distances generally used; 40 yards is needed to count the percentage in a 30" circle drawn around the (perceived) centre of the pattern (which may not be the aim mark).

For some reason, 16 yards is used for Point of Impact. I think because 1/4" at the comb will equal 4" at the target, but I may be wrong on this?

No, you're right but it's usually expressed as 16 yards, 1/16" and 1" at the target.

This is what I was taught, the tightest choke, at 16 Yards, take the shot, at that distance it should be a nice tight pattern now measure the pattern and find its center and for every inch you are of then the stock needs moving 1/16 of an inch.
