Important Info Regarding Steel Shot
The choke (before constriction) in all modern shotguns has been established based on the pattern performance of shot shells loaded with lead shot. When using steel shot shells,you will notice a different performance in pattern density versus the established lead shot pattern, because the steel shot is harder and lighter than lead shot. You should be aware of the following differences and cautions: Never shoot steel shot loads in a full choked barrel or an improved modified choked barrel. Doing so, may cause the barrel to swell or rupture. In general, steel shot fired with a modified choke will produce the equivalent of a lead full choke pattern. This will be true of all steel shot sized up to and including no. 2. The established improved cylinder chokes will produce the equivalent of a (lead) modified pattern. All steel shot sized larger than no. 2, and including special sized such as F, T, etc, should be used only with improved cylinder chokes. These steel shot sizes, when used in an improved cylinder choke, will produce equivalent to (lead) full choke patterns. The established cylinder choke or bore will produce the equivalent of a modified (lead) pattern. Additional information concerning the use of steel shot is available from the ammunition companies. When using aftermarket choke tubes, check the mfg. recommendations prior to use.

Shotguns typically will require 50-100rds of ammunition, we recommend a heavy load of 1oz or heavier for break in.
The design of the Turkish T-1919 pattern magazine allows it to be “over-inserted” in certain models of firearms. This can cause feeding issues and/or damage to the magazine. To mitigate this, when inserting the magazine, it is not necessary to seat the magazine with force. Pulling downward on the magazine will often engage the magazine catch in the proper manner if the magazine was over-inserting during initial loading.
If the magazine is stuck, before attempting to remove it, ensure there are no live ammunition in the firearm. To remove any live ammunition from the magazine, you can remove the base plate by pressing in the “O” and sliding it forward (The Star is just decorative and doesn’t need to be pushed to remove the base). Once it has been cleared, hold the magazine release button and pull down on the magazine.
