Thread: 6.5-284

Anyone here loading for this? I'm currently playing around with 142gn SMK's and AR2209 powder. Any thoughts or "common recipes" that get results.

I won't use 2209 in my 6.5AI. 2209 is a quite aggressive powder for some reason. I use WW760 (and 142gr SMKs) in my AI which has fractional better performance than a 6.5/284. My barrel life is looking to be a lot greater than a 6.5/284 with similar performance. In Ackley speak that is to be expected.
Mate has 2x 6.5/284s. Uses 139gr Scenars. First barrel toast quite early using 2209. Now he is using 2217 which gives as good accuracy and to date his throat advancement at the same round count is less than when he used 2209.
2217 may be too slow though for shorter barrels.

50.5gr of 2209 with 140 Vld here

52.5gr Of Reloader 22 with 140gr AMAX for 2960fps from a 26" tube for me

What's a good starting load with 6.5ai with 760? using 140's

Surly a starting or mid range 6.5x55 load would be sufficient or do you think they are completely different?

I have read use 6.5-284 loads but am not 100% sure.

I tried 2209 in my 6.5-284 but didn't get the speed or accuracy i was after. Ended up going to RL17 and get around 3k with a 140gr berger hybrid from a 30" barrel.

toby your going to be using x55 cases to fireform so why should there be any reason to swap loads, you should get some good speed tho.

going to chrony my 6.5 again tomorrow but not sure if chrony playing up as gun shoots lazer

So I'll fireform using factory ammo and then start a test load from inbetween max and min. How high do I go?

Until you start seeing pressure signs or your teeth rattle around after you fire a shot

Using 52gr vihtavouri N560 in mine, pushing 140 grain gamekings @ 2990

Kick this thread back into life around then or start a new one just on the 6.5x55AI.

Did you solve your dies issue? Or is that after duck shooting as well
