7mm 08 AI Questions

[c-fbmi]

WL.............1-9 twist will work just fine for a 284, even with 160+ gn bullets. 1-9" is factory standard for 7mag as well

FYI I'm getting 2800fps from a regular 7-08 with 150gr AB Long Range... True BC of 0.576. H414 and CCI 250 Hornady 9th ed book load.

Of course I still want more...I do agree though that the 284 is your best compromise as your Kimberly can't take the reaming to a magnum.

im re thinking the .284 Winchester at the moment, not the AI now.

You see im hunting quite high country a lot with this Kimber on back pack hunts and such, im noticing a lot of the shot oppertunitys are from the fatter side of 200m out to 400m , further if you wish, but big valleys and crevises can really limit in how close you can get without being on their face and that can seem 'thick' , whereas it seems open from the other side...

its always pretty windy up there too, so even though shooting across a gulley, the wind thru it may be fairly 'hooking' , so I am thinking having higher velocity with a better 150 grain bullet would be more suited.

I have had a bad run of two good Deer where I stuffed up the shot, one a Ranking shot which must of been off , drew blood but even on some back up shots on the run we weren't able to hit / find the deer..
the latest was a surprise , in the moment shot on a Stag what had spooked an ran directly away, as it slowed an turned to the left I thought i'd put on right in the boiler room just behind the shouilder... I followed up after I thought it stumbled... but I had givin it too much lead and most likely 'pulled' the shot with the lightweight rifle off hand..
but no blood on running marks for almost 200m had me doubting my shots with adrenaline (as I was on the minibike for ease of travel to base camp).
the stumble was litteraly him dislodgin a rock from the earth as he made a dash..


Not that this has much to do with the Calibre / Cartridge .... its just the Deer come out of the thick into the opens, I think the 7m08 can be a bit slow of a killer, lacking hydrolic shock on the big Sambar stags, meaning they are likely to Run a distance - maybe up too 200m well hit-
so I am thinking along the lines of 2 holes for insurance.....

2800fps with a pretty stout 150gr sounds pretty good for longer-thru- wind shots and putting decent smack down on the deer..

hhhhmmmm.

I wonder if the Twist rate from 708 suits the 284 however!!

I built my 284 on a Rem 600 for just that purpose. If you buy or make an extended mag box, you can throat it a little longer for 3.1-3.2" coal, which will give you ballistics right even with a 280 Rem in a short action (lighter) rifle. Best sheep gun I ever had. Your twist rate will be 1-9, which is pretty stabdard for any 7mm. - dan

So today I got around to talking to the Local Fly shoot guru personal gunsmith, about the 708 Ackley and the 284 Winchester, a reamer and someone to do it..

turns out a mate of his , has been doin the gunsmithin the past few months for Him, while he does up a few stocks etc.. But says its goin to be at 'Mates rates' after Christmas time... I need to first shot the Barrel an its contour up around the chamber.... then go from there if the 284 is guna work..

if not its definatly getting Ackley Improvised!
