[QUOTE="Fiftydriver, post: 176339, member: 10"] Roy, I have not seen this yet with the 270 AM but that is not to say it is not a real possibility as you know. I have only tested one rifle with this powder and it worked well but certainly this is something to pay real attention to. In my smaller caliber AMs, the 257 and 6.5mm AMs, there is no safe stick powder to use in these because of the smaller bore size and powder bridging occurs nearly 100% of the time and as you say, not a pleasant thing. Interestingly enough, I have tested this with the 257 STW. The reason is because I have seen one rifle have problems when another with the same load did not. Why? No idea, both chambered with same reamer, same ammo used, same brand of barrel used. I can not explain the reasoning here as to why some have problems and others do not. As you mentioned, ball powders prevent any possibility of this happening. If you want surplus, 872, T870 and 860 will work great. If you want a commerical powder, H870 if you can get it, AA8700 and US869 work very well. Kirby Allen(50) [/QUOTE]
