Went out hunting today with my new CVA Optima. Was shooting the 240 gr XTP Mag 45 cal with Harvester crush rib sabots over 90 grs of BH 209 Fed 209A primer.
At the range I got good results shooting a little under an inch at 100 yds. After the hunt ( No luck) I decided to shoot out my ML rather than just pull the load. When I shot I got a poof burp flop...Could hear the sabot/bullet exit the barrel barely and could barley feel recoil so I knew something was wrong...Pulled the breech plug to confirm the round exited the barrel and it did.
I did notice upon loading from a clean barrel that the sabot/bullet combo went down UNUSUALLY easy. So much that it did stick in the back of my mind. When I tested at the range I did not use the above load until after I sighted in at 50 yards. ( I had some 240 shock waves in 45 cal that had the sabots with them, black non crush ribs) So the gun had about 5-10 shot through it before testing.
Could the problem be that the black crush ribs are just too loose as a sabot? Should I order the regular harvester black sabots for a tighter fit because as I read about them them are slightly thicker that the crush ribs?
I also looked at my targets again from that day and I did notice with the above XTP combo that my 1st (2) 3 shot strings were vertically stringing. From my reloading end that is normally a sign of velocity deviations.
I do not know if the TC shock-wave sabots are the harvester regular black ones but did try loading one after I got home and there was sufficient tention when loading. Not alot but enough that I had to use a minor amount of force to seat the bullet sabot combo.
