Got these last night from the Montana Bullet Company. Trying to see have anyone loaded this type of bullet with LongShot and or BE-86. If so would you mind sharing your load data. These will be loaded for my G20 with BarSto barrel.

I just use the Hodgdon book (https://u5125847.ct.sendgrid.net/ls/click?upn=EhWSnK18-2BtF-2BaSATmrpWwHuIpFr-2B96YK-2BeoQIPCTI9tr-2FWvO9uvFikPhDoF5Omsplde-2F3gN5HAJul6xdWigAnVbywHB64LT-2FQLlXlnUZBDTt8Tt26Za1DtT7iDWmBZUGcd4H2nCBSjjaLDo3zlByMOMdsiGwXq2WmJsctJWEq0c-3D4xNA_h6t5zsVS6RI2fPGPZrLR2GWs010Jlx8r46vapocLH9g-2BoeLb9szAnppaj2WFztrjDtWCnPrP1CEXe3iC53I1MFF4awuQoDDZVK6c2fJTWLTnO26bl-2F9Oka0VwSBNExIPf7HEpd4qqXM94fAclcb1hFbHoHwGvfzitPdcHcLEVO4-2BeQ9svbMNrYnDuETOnOGNJ8liAUyjDfOeYuu8GZDuMqTk7x-2B0TrVKA7pkrAzFooI-3D) data for Longshot. Even though this is for a jacketed bullet, it should work find for a cast bullet. You should expect to hit the listed max velocity at a slightly lower charge due to improved bore seal of the cast bullet.
I have not used BE-86 with any 200 grain cast bullets to date. If I were I would start around 6.5 grains and work up to a max charge of maybe 7.2 grains or a max velocity of 1100 fps. Watch your case head expansion with a micrometer as you work this load up. This is very much off book and use at your own risk.
Popapi have a look at the data here: Then decide what you want to work up yours with...
This is the 220 grain from UW

Thanks guys I appreciate everything!
All these did well. Thinking 8.4 or 8.6.

What powder did you test with for those numbers? :-[

@Shadow that UW 220 you listed it shot. 1146, 1165, 1170 and 1172.
Yes UW list the 220 HiTec as 1200 fps and not quite making the advertised, I think he test with a 5" barrel!
