7mm Quandry

Posted this a few days ago in the 7mm Forum but didn't get much feedback on the seating depth issue.

Hi Guys,

Bought my new to ne F-Class shooting rig some time ago.

Love the 6mmBR barrel but now want to switch to the 7mmWin barrel. both 30" Kreiger's. 1 in 9" twist on the 284Win barrel.

I got loads of prepped brass and around 150 loaded rounds all loaded with the now-defunct 164 AMAX's.
So I will enjoy the Amax's until they run out but then what?

I have 700 180gr Scenars on hand which I would like to shoot. I appreciate i will need the free-bore attended to.

Question; should I persist with the 180gr Scenars or sell them and get something else. Again, this is for F-Class long

I was worried about the depth in the case these would need to be seated Using the Hornady case length gauge it is 65.34mm long with the Scenar touching the lands. See attached image. It would need to be seated at the bottom of the red line which I drew around with bullet seated to the 65.34mm (2.5724409 inches).
Not sure that is even practical with it being seated so low into the case.

What say you?

Peter

What say you?

1 bullet diameter is the preferred depth for hunting rifles and although this is F class and maybe a little deeper than you'd like why sweat it when you can just suck and see while working up the load.
That's what I'd do.

I have great success with my 180 Scenar L's in two of my Fopen rigs. On good days when the conditions and I are in sync, I get anywhere from .800 to 1.2" elevation at the waterline at 600yds. I point them when using at 1000yds. A little more BC and trajectory. But yes, you are correct, you may want to re-evaluate your freebore. I primarily jump these bullets but I have have found they do well jammed, just not a lot of difference to switch seating depths. I too run a generous freebore.

Thanks guys,
think I'll go down the re-bore for more free-bore then. I'll try a couple at the shown seating depth and jammed just to get a benchmark.
