I used to purchase Remington Thunderbolt .22 caliber (I think they were called) and had the same problem.Misfire aftermisfire. Although you could try them a second time and they might actually go off. I used them in my revolvers and pistols. After the first brick I went back to Winchester Wildcats and have never changed.

As for their #11 caps. I use them when there is nothing else around. If there is anything else out there, I purchase that. I just bought 20 tins of RWS 1075 and 10 of CCI standard (thinking they were magnum) and those would be my choice. I just get too many misfires with the Remingtons. I have enough caps to last me a long time.

Now I do use Remington #10 in my black powder revolvers and they work fine. I wonder if it has something to do with the fact the blast is not being bounced around the bolster and snake, but instead shoved directly to the back of the powder charge. I have no complaints with their #10. (good thing as it is all I have been able to purchase).
