Just a question for you sevenheads , what groups are you getting or expecting at 300 ? constantly ? say 7SAUM, Chop

That's got to be a trick question !!!
Who uses a 7mm at 300.

No trick question , I just want to know how fantastic they are, some say they will eat 300 ? I wouldnt know, Chop

Chop you just stick with the 6mm will ya - 7mm is hopeless

who uses a 7 at 300 you ask , me

Yeh I seen ya shoot a 60.9 at Glenrowan a few years ago

My impression is a good 7mm will be capable of 60.10 at 300, but it'll be more likely to get one at 800. An average 7mm will still hold the 6 ring at 300, which is the main thing that matters. Although even that doesn't matter at some events e.g. Tassie Queens starts at 500.

Has anyone down loaded a 7 for the shorts ? I can recall that was the trick and flavour of the month for 308 , Chop

I usually use 168s up to about 6 or 700.

That makes sense, reduction in recoil ?

Yes, and easier on brass. Even the SMK175s are noticeably easier on primer pockets than the Berger 180s.

I built and shot a seven some time ago, and cranked more out than in , so i got rid of it , too good for me poor bloody coaches in FO have a job, Chop

chopper,
any good 7mm rifle should easily hold the x ring at 300 if loads are worked out properly.
the 168 gn bullets equal the 140 gn 6.5s in b.c., so if you want less recoil, have a barrel chambered for something like the 260 rem.
alan,
would not case life be related to balancing powder charge to bullet?
keep safe,

Not that I shot for group Chop
My rule of thumb is .3moa average
The one occasional tight group doesn’t necessarily make it a winner.

I would say the 6mm would be more likely to group tighter at that short range.
I usually determine my grouping ability (potential Accuracy) on the av SD of group.
