Disclaimer " I sent email to the maker last Thursday evening and was told i would receive a reply in 24 to 48 hours. They have not responded." I bought fancy reloading powder funnels and just last Thursday got around to using them. Long story short they are not as good as my plastic RCBS funnels and I have returned to using the plastic funnels. I have always been careful to make sure all the powder I put in the funnel gets into the case I am loading. The new funnels have a brass small end that allows them to stand up when I have charged a case. The plastic has flat side so it won't roll off the bench, the new funnels are round and roll so I set them on end. Even after careful manipulation to see that all the powder went into the case, every time I set the funnel on end there was 8-12 grains of Win 748 that didn't make it into the case now on the bench. So I go back to the plastic and all the powder is in the case. The brass end that goes over the neck of the cartridge to be charged is machined such that the should contacts the funnel and will not let the end of the neck reach the funnel and allows a 1/16 th of an inch for the powder to work its way by the neck and end up on the bench. I am beginning to think that the KISS method may be best for reloading and all this fancy stuff is a waste of time.
