Please don't let the yellow plastic skirts cause you any headache. In my experience they always blow into two pieces. One round frizzie halo part, and the inner ring directly connected to the powerbelt post stays with it all the way to the target. This is because CVA uses a different(Cheaper!) skirt polymer, closer to ABS plastic, that is not as tough and resillant as the 50 cal skirts[:@] I never even spin the skirts anymore, just load and fire
This does not effect accuracy at all, and is normal for the 45cal PB's. I would strongly recommend the 275grain or better yet, the 300grain Platinum. And continue to use
Only 70grains of powder.
This load will be a real tack driver, and good too at least 120yards
If you do go with the 300g Platinums,
Do Not Spin, or take off and on the skirts!! These are Great! And need no messing with at all. If you do, you run the risk of loosening them too much. And they Will Not grip the bullet tight enough to keep it in the barrel. PB might jar itself free and slide out, or worse yet, slide aways down and stop. This would make for a very unsafe condition!!
Just my 2 cents.
