Reply With QuoteMine would and shoots them beautifully out to 800. That's as far as our local range would let us go. I can't remember the actual charge weight but mine preffered H4350. Half moa at 100 yards.
will a factory twist .243 (9.25 I think) -stabilize 105' Amax's ?

sweeeeeeeet !!
I tried 107's & 115's (VLD) in a 1 in 10 twist. (It was supposed to be a 1 in 8) Out of the 10 rounds I fired, 4 actually hit the target board. Sideways.
That was my first experience with "keyholing".
Everything at 90gr or less is great.

I called Hornady and asked them about it what twist would work when I was buying a blank for my 6mm-WSM. The Hornady Tech stated that 1-9" was optimum for the 243 types of speeds which he stated were tested up to 3000fps. I asked about the 9.25 Savage twist while I had him on the phone (I waited 15min so I figured I'd hit him with a few questions) since my 243AI is a rechambered Savage SS Varmint Barrrel, and he said the the .25 twist difference according to his data should not make a difference, but he said he wouldn't run them slow.
Take that for what its worth.

Hey Boots...
That's similar to what I was told by a few guys. Run them hotter. I don't like running loads too high. If it works at the low end, it's good enough for me.
Saves wear & tear on the brass, rifle & my shoulder.

Well my slower loads so far the 6-WSM which is about all I have used the 105's in much are in the 3300-3400 range. But with a severe overbore like that you can't help but just run it fast.
For most of my calibers I am with you on hitting the slower accuracy node, but with 58's in my 243AI and 105's in the 6-WSM its all about the speed. I am going to have to start working up a load for the 22-250AI one of these days, we'll see if that one stays slow and safe or fast and wild. LOL.

If you can get them over 3000+ fps you should be alright with a 10 twist, I have a 12 twist 26" in 243 and get them going 3200+ fps and they do fine.

RUMs are like woman in Stiletto heals, you know they are going to put you in the poor house, but that has never stopped anyone from pursuing them.
HV 100 my 243 max 1 loves it. Same data with 105 amax to 1000 yds.
