Hi Guys,
Any experience shooting Hornady .243 (6mm) 105 gr. A-Max from a 1-9.25 twist rate barrell? The ballistic coheficient is really atractive (.500) and I think would do a good job on Deer.
Thank you.
Fede ???

I have used it to punch paper at 100, & 200 yds.

in my rifle, McGowan barrel, Rem-6mm shoots pretty good.

the barrel is a 1:9

top of the twist range in my experience; buddy's 6mm 40x (1-9") shoots the 105s (and 107 smks) very well, however, my 6mm VLS fails to stabilze either of those bullets with its 1-9.25" twist.

I worked some sub 1-inch loads with it for my daughter's Savage youth rifle. Hopefully we'll be able to give you some info on terminal ballistics by the end of this month.

Don't know about that twist rate, but my 1:8 twist (I think) Mc Gowen likes them very well....

Load is 40.5 gr H4831sc in Lapua brass with Fed210m primers - 105AMAX loaded 10 though off the lands, 2 thou neck tension. It's not a speed demon, but pretty consistent accuracy.

I tried jamming them in the lands but kept getting good 3 shot groups(one hole) with 2 flyers (not real bad flyers, but out of group) - I don&#39;t think I was using enough neck tension to keep them jammed when I closed the bolt and was ending up with all just touching lands. Rather than mess with changing neck tension, I tried seating them out a bit and the groups closed up. I shot 2 3-shot groups yesterday that looked to be <.4" (didn&#39;t measure them) at 200 yds while load testing .......

Haven&#39;t shot anything but paper with it yet..

I built some with Retumbo shot them in a 9.25 twist out to 600 yards, very accurate.
