What the hell!!! Im in too!
Nobody has mentioned the 284 Shehane? its the most you get out of a 284.
Im getting all my stuff together to build a standard 284WIN with will achive 2900 ish with a 162-68 gr bullet from a 26" tube, the Shehane will do this with ease. The reason that Im not going Shehane is the cost of Dies for me are too much for the 50+ FPS gain, I can pick up 30 fps ish with a longer barrel which Im paying for regardless of lengh, Im going for a 28"
The rat in the woodpile will be its OAL for factory stuff, mines a Barnard so I dont care but if you are single feeding dont worry about it.
As liltank stated is is very under rated.
If this was your only rifle for target and hunting and you want a "cost effective" round then consider it, if you want a new barrel every 1000 rnds get a 6.5-284 ,barrel manufactures love them!!!!
Exbal tells me a 284" 162 AMax MV of 2900 fps @ 600 yrds will hit with 1543 ftlbs the Shehane will launch a 180 gr 284 Berger @ 2900 fps @ 600 yrds 1848 ftlbs in comparison a 178 gr AMax 30 cal MV of 3000 fps @ 600 yrds 1505 ftlbs.
Anit it beautiful !!!
The only consideration really is your action.
I had better change my log in name
All the best.
