243 Ackley...faster twist and "lighter" bullets?

I had my .243 AI done with a 1-8" twist to shoot the Hornady 105 A-Max at longer distances, and it's doing a pretty good job of that so far.
I'd like to load up some 80 grain Sierra Blitz, and some 87 grain V-Max for whacking coyotes, but I have no idea where to start. I've got a BUNCH of Nosler 70 grain Ballistic tips on the shelf too.
Has anybody shot these bullets at higher AI speeds from an 8 twist?

I don't expect any of these bullets to be fur friendly at the AI speeds. I'm actually hoping they'll be very fur un-friendly.

I like to kill 'em too dead to kick.

I shot these yesterday from my 243 Ackley 8 twist. 87 VMAX over 38.5/ Varget and CCI 200 primers. Not a load I would have chosen but it was the only powder I had on hand.

Four rounds in just over 1/4 and the last one brought it out to just over 1/2. Should work OK for close in prairie dogs.

My 105 AMAX shoot a tad bit better but not much.

Would a guy have stability problems...etc...etc...trying to use those bullets in a 9 1/4 twist thats std in the Remingtons? I bought the HD barrel model just to shoot heavier bullets at "long range"...long being relative of course
 
sully,
the 80 grain Sierras shot great in the 9 1/4" twist factory barrel I had before I got the 8 twist barrel screwed on.

I got the 8 twist for 105's, 107's, and maybe even 115's.

Is that a hot load?

The Sierra book lists 38.0/Varget max for the standard .243. It shows no sign of high pressure in my rifle but you should always start a little lower and work up.
 
Jeff,

One of my favorite accuracy loads for the 87gr V-max is 37.3gr 4064. I would load some up and check it out, for fireforming. Then take it from there......
