anticus Posted February 24, 2023 Report Share Posted February 24, 2023 My Sten is in NFA limbo, but I’m using the time to search for good deals on mags, accessories and ammo. About ammo, what 9mm is best for feeding the gun ? Is 115 Gr FMJ the best choice ? Any ideas on this and other goodies to get for the Sten are greatly appreciated !

tommyboy Posted February 24, 2023 Report Share Posted February 24, 2023 My Sten pretty much feeds any 115 or 124 grain ammo reliably with the exception of Remington UMC which tends to be a bit underpowered compared to the other bulk brands like American Eagle, Fiocchi or Winchester white box. Any failures to feed are almost always magazine related. You’ll definitely want a supply of mags so you can sort out the ones that reliably feed in your gun.

APEXgunparts Posted February 24, 2023 Report Share Posted February 24, 2023 I have run my STEN's and other 9MM SMG's (MP-40, Beretta 1938/43, SWD-M11/9 ) on the IMI manufactured 9mm SMG ammo that was intended for the UZI SMG. It is truly an SMG load and not recommended for 9MM handguns. APEX sells it on GunBroker now (we sold a lot of it at KCR and SAR), there may be other sources. 9mm Submachine Gun Ammo 500 Rounds Israeli IMI MK5 STEN firing Israeli 9MM subgun ammo Richard 1 Link to comment Share on other sites More sharing options...
skoda Posted February 24, 2023 Report Share Posted February 24, 2023 FMJ for feeding and a little hot to push the bolt all the way back. Russian cheapo isn't hot enough for mine. I run reloads that are just over the middle of the recommended range from my Speer reloading book with 115 and 124 bullets. Link to comment Share on other sites More sharing options...
RoscoeTurner Posted February 25, 2023 Report Share Posted February 25, 2023 The two I have never have had a problem shooting any 9mm ammunition I have shot them with. Factory or reloads they handle both equally well. Link to comment Share on other sites More sharing options...
1gewehr Posted February 26, 2023 Report Share Posted February 26, 2023 If it matters, the original ammo was the German 08 spec which is pretty much identical to current NATO-spec. It's 124 gr at about 1200fps from a 4" barrel. A bit hotter than SAAMI, but a bit less than +P. I stay away from Remington 'target' 115gr as it's too weak and causes runaways. I also avoid steel case as it's generally pretty dirty and if there's a chance it causes extra wear on 80 year-old extractors. Link to comment Share on other sites More sharing options...
StrangeRanger Posted February 26, 2023 Report Share Posted February 26, 2023 I'm pretty certain that all the 9mm that Britain produced during WWII was 115 gr Link to comment Share on other sites More sharing options...
NFA amnesty Posted March 1, 2023 Report Share Posted March 1, 2023 Winchester White Box is good when you balance cost/performance. My C & R Sten and MP40 tube have no issues with it. I also use Perfecta 9mm with both weapons and again zero issues. Link to comment Share on other sites More sharing options...
2ndArmored Posted March 1, 2023 Report Share Posted March 1, 2023 I've found Wolf 9mm to be dirtier than most and my toys get petulant with steel-case ammo. CCI Blazer 115gr FMJ has worked well for me. Link to comment Share on other sites More sharing options...

DARIVS Posted March 3, 2023 Report Share Posted March 3, 2023 Winchester in the white box. Best performance for the money. Works great in the Sten, MP-40, and even the finicky P08 Pistole Parabellum. Either 115 gr or 124 gr. 1 Link to comment Share on other sites More sharing options...
