Thread: .260 Loads

If in doubt!!! N560 for everything!!!

H414 is good for another 100 fps over AR2209

Got some W760 for him to try....same thing isn't it? But I fund in my 243AI that it was quite temp sensitive and I had to run a summer and winter load ...

If in doubt!!! N560 for everything!!!

N560 is a double burn powder like RL17 and V100 but V100 is much nicer to work with being shorter cut with rounded ends... goes very well in the charge master

Although 17 got more speed with 160's in the SAUM and 280AI over both N560 (just) and V100 but v100 were the same speeds with 140's (Didn't try with the 280AI) so all worth a try if chasing every drop of speed

Normie, I have a 260AI and shoot 140gn VLD and Amax exclusively. While the AI version of the 260 is a little different (bigger capacity) i can share my experiences in summary:
2208 - too much pressure before speed with 140gn pills
2209 - better than 2208 and you should achieve 2800fps easy enough. Be aware you will be at the top end of pressure and there will be a fine line between acceptable and not
RL17 - I was unable to maintain consistent accuracy with the little bit of trying that i did so discontinued this
2217 - I followed Kiwi Gregs lead on this and even made a drop tube to help compress loads. I was unable to get sufficient powder in the case to give velocitiy required ( I am targetting 2950fps with low ES)
2213sc - highly accurate repeatable load (low ES), can't comment on capacity and speed relative to the std 260 case but worth a try
N560 - simply put - the best. Low pressure, good velocity (I use 50.1gn for 2960fps with VLD's and 50.6 for 3020fps if I really want to be ambitious). ES is great, case life is great and I haven't noticed any difficulty on the chargemaster
