Example:
You have checked your gun and your optic.
The weather is calm (22 rimfire is very sensitive to wind).
You started from a very clean barrel and
you have shot enough of that particular ammo
so you KNOW the barrel is seasoned.
Then, you start shooting for groups.
Let's say your groups are un-acceptably large like in this photo.
The picture bellow is one of the targets I have shot
during the early proto testings from 25 yds. Each group is 10 shots.
As you can see, that particular ammo cannot group for sh!t.
Do not waste any more time and energy with that ammo.
If you are sure it is not you or the gun, then
there is no point in starting screaming
that she doesn't love you (because you have a small ####).
Instead, calm down, clean, change ammo, season the barrel an start again.
But down the road, the exact same barrel that shot the paper in the first pic,
after cleaning and seasoning with different ammo,
shot this paper (25 yds). Again, these are 10 shot groups.
Here, because some of the groups are smaller than the average group in the first picture,
you may want to pay more attention to this particular ammo.
You may want to crank up the magnification (if you have more)
and maybe spend more time trying to do one more paper.
Do not rush because you may get the barrel too hot.
Make a note to yourself about this ammo, but don't go yet to the store to buy
the whole inventory of that particular ammo.
Maybe you should continue testing other ammos as well.
Another example:
This above is an informal target (not in test)
shot with 4 kind of ammos from the same barrel and the groups side by side.
Seasoning was achieved with each ammo
shooting other targets on the range.
Then, when the barrel was seasoned with a particular ammo,
one 10 shot group was put on this target as comparison.
After that, I cleaned, changed ammo, seasoned on a different target
and come back on this paper and print another 10 shot group,
and so on, I hope you get the idea.
Ammo used for group 1 doesn't do well.
Next, ammos from groups 2 and 3 might shoot better (or they may not)
but I wouldn't bet too much on them.
Ammo from group 4 shoots the best when compared with the other ones
and I would do more testing of that.
After the tests made for DlaskCo were finished, one young shooter
was bugging me to go try the first commercial barrels produced.
Me, I was finally relaxing, smoking, snacking, drinking coffee
and watch other people having a taste of the pain I had to endure for months.
The difference was that I tested barrels AND ammo,
and he was testing only ammo in some certain given barrels.
In about 6 hours of range, he tested about 5 types of ammo,
and he chose the most consistent ones of the day for these 2 barrels.
These are the final targets he shot with the best ammo tested in that day (25 yds, 10-shot groups).
When back in Lower Mainland, we took
dinner at Fresgo. Waiting for the food, he fell asleep at the table. LMFAO
Welcome to my world of pain, Mike.
Other people more experienced may not need too much testing
to have an idea if there is a happy match between things to be tested.
Way before the real tests,
when trying the compatibility between the rifling and the chambering
intended for use in these barrels,
one day Mr Joe Dlask shot this group from the pic above.
It is a group of 5 or 6 shots from 25 yds.
I asked him why he didn't shoot all ten rounds.
Very calm and trying not to smile, he explained that he is a busy person.
Translated, that meant that I have to go to the range to do
the rest of the test of about 300 rounds (because I am black).
Sorry for the large pics, I will downsize as soon as photobucket allows me to.
