No It is NOT Recommended. The Beeman P-17 has a rifled barrel. Forcing a bb through the barrel will ruin the rifling and the accuracy of the pistol permanently.
pellet=no bb's= 6mm plastic not copper.
never use .12 bbs. they are very inaccurate. Buy some .20 tsd tactical bbs, never use crosman
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
The stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.
6mm of either .12 or .20 gram bbs. 6mm of either .12 or .20 gram bbs.
no
I use .20g bbs because I think they go better with that gun. But it really doesn't matter which you use
Low powered guns shoudl use .12 gram or other lighter bbs, medium AEGS shoudl use 20 or slightly higher. High powered spring guns should use 28+ grams bbs.
no
No, it is not kosher.
NO.
No, they are too small and will jam the gun. Never try to use metal bbs in airsoft guns or vice versa.
