JimFromFL Posted January 2, 2004 Report Share Posted January 2, 2004 Using Clays (3.7-3.9g) is outstanding with my 1911s, but with the Thompson it appears to sputter. It sure slows down the rate of fire, but appears to cause some reliability problems. Anyone else experience this? Link to comment Share on other sites More sharing options...
21 smoker Posted January 2, 2004 Report Share Posted January 2, 2004 Jim,.. I seem to have the best luck with Bullseye, if I remember correctly about 5.2grs with 230gr. rn lead or fmj. Unique at 7.0grs as a backup.Hope this helps.KEEPEM`SMOKIN`,out. http://www.machinegunbooks.com/forums/invboard1_1_2/upload/html/emoticons/wink.gif Link to comment Share on other sites More sharing options...
JimFromFL Posted January 3, 2004 Author Report Share Posted January 3, 2004 Just wondering.... What primers are you using? Link to comment Share on other sites More sharing options...
catnipman Posted January 3, 2004 Report Share Posted January 3, 2004 Clays is one of the fastest burning powders, and I didn't really consider it very suitable for TSMG .45ACP loads. I'm using AA No. 5 sucessfully, which burns quite a bit slower (though is also quite dirty), and I know a few very knowledgeable people here really like Winchester 231, which is faster than AA5, but slower than Clays, and has been said to burn pretty clean. Take a look at the relative burning speeds at this Hodgdon link: http://www.hodgdon.com/data/general/burnratechart.php I think the general rule of thumb for handgun loads is that the bigger the caliber, the slower the powder needed, and rifle loads use much slower powders than handgun loads. The TSMG is kind of an unusual situation because the cartridge is a pistol cartridge being shot from a rifle. Link to comment Share on other sites More sharing options...
21 smoker Posted January 3, 2004 Report Share Posted January 3, 2004 Jim,...I use Winchester standard large pistol,unless somebody offers a super deal on another comparable primer. Link to comment Share on other sites More sharing options...
JimFromFL Posted January 3, 2004 Author Report Share Posted January 3, 2004 Mostly use CCI Primers (#300). Currently purchased Federal Primers and will be giving them a try. There is an item I have to check and will make some modification. Afterwards I will post back with the results. Link to comment Share on other sites More sharing options...
Supershooter Posted January 5, 2004 Report Share Posted January 5, 2004 I see by Hodgdon's book that they recommend Clays powder for not only shotgun but 45acp and 38spl loads. A local reloading company made up some 38spl indoor range loads for a police department with Clays powder, I believe because it is clean burning. However they had some problems with ignition and had some slugs stuck in their barrels. I got a good deal on some of this when it was returned and had about one plugged barrel per box. From the different levels of recoil and the variable sound levels from load to load it appeared that velocity was really up and down. Therefore the reason for the sputtering Thompson. Since a slug stuck in the barrel is a very bad thing for a machinegun, I would stay away from the Clays powder unless you can compress it for positive ignition. ------Super Shooter Link to comment Share on other sites More sharing options...
