I ordered several boxes of RIO 12-23/4 #5 when Cabelas had them on sale they have been back ordered until the end of November.
Still the price was not much different than premium waterfowl loads. Although since I don't have them yet, who knows.
I have loaded bismuth shot with good results and have found that it is easier on my teeth. However it became hard to get and expensive. I also have had some quality issues with shot I purchased.
As a lifelong reloader I believe it is a requirement that I happily spend a bundle on shotguns, dogs and putting gas in my truck, then fret and complain about the cost of ammo and components.
I talked about ITX with a person from this site, and got interested. Since then I have been loading ITX shot and doing a lot of patterning on paper and field testing on ducks, geese and pheasants.
So far I am amazed at the results. I am mostly loading #4 (which actually mics 4.5)ITX 10 and my partners and I have found it to be very lethal. I am now only loading 7/8's and 1oz, 2 3/4 loads.
They pattern the best for me and when I do my job clobber ducks and geese.
I am very interested in hearing from anyone that has had experience with ITX 10. Inparticular about pattern in doubles with lengthened forcing cones. Pressure spikes with certain loads or anything else. Thanks
