ok, i am getting groups that range from .00 center to center to .125 center to center at my 15ft indoor range. how does this translate to 30 yards? is this a simple mathamatical proportion or is it a geometry problem?

i calculate that a .125" group(center to center) at 15 feet will spread to .75" at 30 yards. that is a simple proportion. does that sound right?

you math guys help me out here.

i one hole .177, no spread groups using beeman FTS double golds.

Hector??

It's a simple ratio - multiply by 6.

experience tells me that groups grow MORE than the geometrical proportion would tend to indicate.

There are statistical rules to come up with a scientific answer, but that is not the end or gist of the forum, so let's leave it at a Rule of thumb:

"Size of expected group goes up 15% faster than distance would dictate"

So, twice the distance, multiply group size by 2.3

Three times the distance, multiply groups by 3.45

And so on.

In your case, 30 yards is 6 times the 15 feet you have in your office/indoor range, so I would expct groups in the region of 6.9 times the 0.125" (1/8), which is, about 7/8".

Now, since I am starting from your WORST group, I would also expect to see the 7/8" as your WORST 30 yard group.

There are lots of added variables on top of distance, things like wind, light, shimmer, position, rest, etc. all change when you go outdoors.

7/8" is nothing to sneeze at when shooting IN THE FIELD at 30 yards. Believe me, it is FT quality shooting for about 70% of shooters in the real world.

Now, go out and prove me wrong! LOL!

i think i still need some work. these are from a rest and FT is much more challenging since it is body only. i am stil getting the hang of the proper hold. i have been shooting this rifle for a week after a 40 year layoff from shooting.

your analysis helps me to establish a standard that i have to meet. i think the rifle has what it takes. now its up to me. i will be taking it out to the range soon and shooting at 25yds (thats the pistol target range at the prado olympic range. the airguns use the pistol range.

i will say one thing. that sitting poition that guys seem to use a lot in FT
is hard for me to get comfortable in. my knees don't come up high enough. i have bulky upper thighs from years of bicycling and it is hard for me to "fold up" like that. also, i will have to work on my flexibility so the position is relaxed. i can feel the pull in my lower back.

Let me give you some other markers for FT:

Usually, matches limit the distances where the targets can be POSSIBLY placed by the size of the KZ (all ranges approximate):

between 1/4" and 1/2" from 10 to 25 yards
between 1/2" and 3/4" from 15 to 35 yards
between 3/4" and 1 1/2" from 25 to 55 yards


VERY SELDOM will matches be conducted where the ranges far exceed the 55 yards. We used to go to 65, but we were even commented on by AAFTA for our "Troyer numbers". Some REALLY SICK individuals (tongue in cheek, as I really admire them, LOL!!!) shoot at targets that have a paddle that is 1/4" in a hole that is 1"!!!!!! Not only can you miss the animal, you can miss the paddle while still hitting the hole cleanly and not touch the animal!!!!!!

ROFL!! I truly admire the lot of Californians, from LD to Tim to Vince to John and Robert (whose penchant is more towards the FT course of real targets, but that is another story).

The above rule of thumb is good enough for training and if you go to my good friend Perry Babin's site, you will be able to print as many FT targets as you want with whatever Troyer number of difficulty you want to dream about:

You can also download a set of FT targets for practice at the Mexican Club's site:

http://www.tiropneumatico.com/ft.zip

unzip it and print to your heart's content!

As for the position, I think there are variants to this classical FT position:



Look at this other position:




As you can see, the use of a single point sling strapped to the hand (therefore not violating ANY rules for international FT) is suitable for other anatomies.

You can also take a seat along. As long as it is not taller than 4" at the topmost point. Perhaps this stool-aided position would be better for you.

Dunno, you need to try several positions and see what works best for you.

You still need to work that flexibility, as BREATHING is of paramount importance when shooting and these positions do not promote the best of breathings in us middle aged males. ROFL!

very helpful information.

Whats wrong? you couldnt find a bigger scope? :}

As an old Scott friend of mine would say:

"There's nothing worn under the kilt
.
.
.
because everything is in working order! LOL!

That BSA is a good scope! Really is. Probably the best FT scope ever made, bar none.

It costed me US$400 and I thought it was a lot of money at the time (so did my friend Marty MacNaughton), but I bought it and I have never since regretted buying it.

It has gone through three guns; Two national FT championships, given me 7 FT trophies and a lot of satisfactions.

Yes it's a BIG scope . . . in more ways than one.
