harald Posted August 1, 2017 Share Posted August 1, 2017 (edited) Hi, I got a custom 1911 Caspian with a Schuemann .355 Ultimatch barrel, but are having problems with bullets all over the target. I have another 6" 2011 with a .355 Bar-Sto and this shoots very nice groups with HAP 125gr and plated bullets, but the Schuemann barrel speds all over the target. My target load is 3.6gr N320, the velocity is the almost the same from these two barrels, but the groups are very different I have just fired about 500 rounds in the Schuemann. Do you have any tips to improve the accrucy in the Schuemann barrel? Diffrent bullets or different power? Edited August 1, 2017 by harald Link to comment Share on other sites More sharing options...
RangerTrace Posted August 1, 2017 Share Posted August 1, 2017 I never had much luck with plated bullets and Infinity barrels which I think are very similar to Schuemann barrels. My 6" Limited gun would group OK with them, but all the rest would go 12" at best. Link to comment Share on other sites More sharing options...
harald Posted August 1, 2017 Author Share Posted August 1, 2017 RangerTrace, you descibe the same problems as i see myself. I can shoot better with the 6" strong arm then i can shoot with both hands with my 1911 Schuemann barreled gun. Link to comment Share on other sites More sharing options...
zzt Posted August 1, 2017 Share Posted August 1, 2017 The HAPs are good JHPs, so it is unlikely to be the bullets. The first thing I would do is slug your bore to find out what it actually measures. Then I would try other bullets. The HAP 125 is .356". Try a HAP 115 @ .355" and see what happens. Also, what is the twist rate of your Scheumann? They make 16", 24" variable twist, and 32" twist rate barrels. If you have a 32", it will want lighter bullets. Link to comment Share on other sites More sharing options...
Service Desk Posted August 1, 2017 Share Posted August 1, 2017 Try some Geco Hexagon bullets with the same load of VV 320.... then increase the load to 4.0 grains and use the HAP's. My Schueman barrelled 2011 likes a heavier load compared to STI barrels. YMMV Link to comment Share on other sites More sharing options...
jcc7x7 Posted August 1, 2017 Share Posted August 1, 2017 1st thing I would do is call the builder and tell him what kind of groups you're getting and ask HIM WHY? Properly fit 1911 will shoot a group with almost anything. Obviously they will shoot a tailored handload even better. Feeding can be a whole other issue. Good fortune with it Link to comment Share on other sites More sharing options...

Good fortune with it +1 Unless the gun shoots much better groups with several other bullets/ loads, I'd suspect a misfit barrel and or bushing.
