Chap, I have not found the tightness of a patricular load to be a problem w/BH. Last month I was shooting some conicals and they were not tight by any means. Actually so loose I wouldn't hunt with them and I didn't have any delay w/BH. Same goes for sabots. A friend of mine has a Yukon and the other day we were shooting an he had some of the shockwave superglides that were too loose in my opinon as almost the weight of the ramrod would seat them. He didn't have any ignition issues with it either.
I by no means am an expert-you guys were probably shootin' MLs when I was still in diapers but from my limited experience, tightness of a load has not made a difference.
The powder just came out, so we all are on "level ground", so your reports have more weight than my speculation. Many have said it is like smokeless, but has a little smoke added. I shoot 4198 and 5744 in my smokeless and by far the 4198 will not ignite without tight sabots and crimping the powder down well. If BH shoots well with loose sabots and conicals, that is truly a very great thing.
Thanks for the report. Chap
