Definitely wouldn't heat 'em up much because of the skirt. And prepared to single load. Mostly worried about squibs, and then accuracy.
I just had a range trip where I ran out of my 158 grain load but had the hbwc, and the thought crossed my mind but I decided against it. Squibs aren't the end of the world, but I prefer to avoid them.
My kid really likes the light load, good news, so I'll be loading a lot of it in the future. I can envision some range days where I just get around to loading the hbwc and thought it would be nice to be able to shoot a few from the rossi.
I know it depends on the rifle, but how much higher would I need to go to get out of the squib zone -- and when does it become too hot for the skirt?
Of course, then my kid might not like it as much. I know, just need to load more, speculate less.
