Just burned through a box of the Buffalo SSB 375 grain sabots. Was shooting 90 grains of 777 and getting velocities ranging from 1680-1810 fps. Wanted to try and figure out if there is a trick to getting Sabots to load without messing them up. On a clean barrell I could get them to slide without deforming the tip. I had some issues after a couple of shots and had difficulty getting the sabots to load without deforming the bullet. I managed some 3" groups at 50 yds, but that was about the best I could get. I tried my 460 NE conicals and they group right up at 1". Just wondering if there are any sabot tricks out there to help with loading these bad boys. When I could load them without messing up the tip the accuracy was great. If I had to push hard you could count on the bullet going wild. Just a little frustrated by the whole issue. I may be sticking with the 460's if I can't get these SSB's to group.
First off.. you are swabbing the barrel clean between shots? I shoot the 375 grain SSB's all the time. I had heard that after I bought my life time supply they changed the sabots on them. The sabots I shoot are yellow in color and load like a dream.
Try using the loading jag tip made for Shockwaves. It will fit over the nose of the SSB and just leaves a small impression on the pure lead nose. Also whether this helps or not, I wet the sabot just a little with spit before I load it. I am sure all the water is gone before it reaches the powder charge. They slide right down the bore for me...
I also push them a little harder then 90 grains of Triple Se7en. I am shooting them ocassionally with 100 grains of Triple Se7en or 110 grains of Goex 3f. I get excellent results with them out of my Black Diamond XR and my White Ultra Magnum..
Good luck.
