No luck with bullet to bore, same results with 36g N110 with dry wool wad, lubed wool wad, and veggie cardboard wad, bullet tumbles I've tried several bullets 200g ftx, 250g ftx, 250g xtp, 250g parker ballistic extreme with 36g of N110, and 275g Pittman accumax, 300g xtp, 300g Arrowhead Performance bullet with 60g IMR 4198 all with same results, as others on here have stated that barrels with wide lands are harder to get the bullet to swell into and grab the lands, and the lands appear to be very wide on this SSK barrel and I'm sure that this is the issue, I think I'm gonna pass on duplexing with my barrel diameter of.997, I'm done with bullet to bore with this barrel, it shoots Sabots very well I'm just going to stick with them, thanks for all the info, and for all the advice from the people that offered it me.
