I dont hear much about the 7mm 08 AI, , Who has had a play and could it be a good ONE gun at a Queens ? Chop.

Yes I reckon it could be a great 1 gun for a queens but so is a 284

Ask wild dog about them. He and Vince ran a couple up and they were working very well.

Thanks Dave , I guess my big question is ? if you had a choice of ONE GUN , which would it be ? Chop.

Chop,
I have been shooting a 284 Shehane for the last few years at all ranges (300 through) and switched to the RSAUM for this years Nationals. I am happy shooting both all the way but if I was going to choose one all rounder it would definitely be the 284 or 284 Shehane. Great Barrel Life, great accuracy and superb velocity spread to keep em in the middle form 300-1000.

In saying that I think the 7-08 AI, 7*57 AI, 284, 284Sh, 280AI and RSAUM are all bloody good. Spoilt for choice we are.

Most get around 2000 before a rechamber and then maybe another 1000.

Rumours are Richard and Rod Davies have/had some with double this number and still shooting well.

Like you said , Rumours :roll:

Here is my 7-08ai
I am still developing a load for this rifle but it is showing good velocity.
It had its first run at a teams shoot at Rosedale on the weekend. Gave me the chance to validate my velocity and get an idea of its wind drift characteristics.
Time will tell how effective it is for F-Open.

Yes sorry Rich - I should have said the information came from the horse's mouth (or horses' mouths in this case)

Richard,

Interesting case choice, can you get enough 2209 in a improved 308 case for a 180 to do 2840 or do you go back to 2208. If not how do 168gr work ?

ben,
the 7x57 ack would be perfectly suited to 2209, and easily do the high 2700 node, and probably the low 2800.
decent brass is available.
lower recoil than the boomers would suit older people like myself.
nice long neck to protect the throat.
shooters who in the real world can tell the difference between the mid to high 2700 node and 2900 are either very very good, or if not are in the land of imaginitis.
keep safe,
bruce

norm,
your chainsaw work is improving with practice.

It would be interesting to see the real world difference in velocity between the 7-08ai, 7x57ai and the 280ai.

I know what the difference is between the .284 win and 7-08ai but have no experience with the other two contenders.
