Need a little help fellas. I got a bunch of bullets in a "deal" recently and am looking for some help loading them. I have zero info on them with the exception of weight. They weigh out at just under 420 grains and are actually a tad smaller than my OTLC 405 grainers. The crimp groove to top distance is the same. I use a lot of Trail Boss powder and I'm thinking I can just start at the bottom load for my 405's and work up? Any thing to be aware of with them only having one lube ring? Any other suggestions or advice would be appreciated.
