Barrel "Conditioning".

[verminhunter]

I have lost count of the number of times I have seen shooters on a sighting in range with four or five different makes of pellets opened in front of them, taking five or so shots with each type and then saying that their gun is not grouping.

Whenever a brand of pellets is changed (sometimes even different batches of the same pellet) or if the barrel has been cleaned then the barrel has to be "conditioned" to that particular pellet by putting at least ten shots (I do 20 to be on the safe side) through it before trying a group.

Different brands of pellets have different percentages of elements in them which affect hardness, coefficient of friction, B.C's etc which all have an effect.

Just thought a "Heads-Up" on this subject might stop a bit of frustration....

Yes you are right neil, what i do and tell shooters if your going to change over a diffrent brand of pellets you must first clean the barrel nicely and properly then run several shots through it and then zero in. the reason to clean the barrel is to remove the tracks left behind from the privious pellet and the new pellet will make and leave its own.

But neil some mothers do 'ave 'em.
