Re: The effect of too much twist and speed
Walker Flatline will be OK if you are not shooting under ICFRA rules
ICFRA rule F2.20.
Ammunition may be commercial or handloaded but loaded in a manner consistent with the ammunition industry’s accepted standards; must be safe to fire in the rifle for which it is intended and must meet in all respects the limitations of any range regulations (e.g. calibre, velocity, muzzle energy etc.). Even if permitted thereunder, prohibited bullets will be those having a core consisting of steel, hardened material, depleted uranium, incendiary or tracer compounds. Also prohibited are bullets of monolithic construction or those having a discarding jacket/sabot.

Yes, not allowed in F class, but how about Fly shoots or long range benchrest?

Re: The effect of too much twist and speed
I was thinking that Stuart would not sell them unless they could be used in benchrest shooting, which is of course the purpose of mike's rifle...
