257 AI testing report

[284allways]

Greetings all.
I am looking for a web based report done on the 257 AI by a civilian several years ago, the report was very well done testing several bullet weights and several powders and using two rifles a ULA m20 and a re-chambered Browning - if I recall. My loading notes and copy of this report have gone missing. I can not find the link to the report.
I do not recall the gents name but can tell you it was thorough and impressive.

Thank you

Cant help you with your report, but a former (?) poster here who went by "257 Ackley" was wealth of knowledge on the round and many other things shooting. You might try sending him a PM. I havent heard from him in many years, hope he is ok. Good lock with your search. CL
