Nice gun Mikey T......I have tried to do the same with my Cowboy gun with 26" barrel.....I don't want to hijack this thread but....there have been questions about my loads using the MT Chambers 480gr. Wide Flat Point Gas Check.....I tested this load with up to 57grs of AA2015 and over 1900 fps. but cut it back to 54grs due to recoil, no other press. signs, W-W cases, Fed. 210 primers. Those 500 gr. shown would not work with this combo as they would take up too much powder space and increase pressure. Another load tested by Mitchell ballistics used the MT Chambers 465gr. FP GC, it was also pressure tested by Accurate Arms.....Marlin 22" barrel...55grs. H-335...W-W cases...fed 210primer....1920fps. Due to reloading circumstances beyond my control however, I can not assume any liability with these top end loads, they are not for recoil sensitive shooters.
