220Swift, fast twists, and BT's

[CDH]

Well, I have the bug for a Swift.

Since I am normally a heavy for caliber bullet fan, I would get a fast twist barrel made. Since I like to experiment with a bit of everything, I was wondering...

What would be the fastest twist barrel Nosler's .224 bullets would survive when shot full power from a 26" .220 Swift? I would expect it to change with weight, so for giggles, list your best estimate for:

40 grain BT
50 grain BT
55 grain BT
60 grain Part.

I know accuracy might suffer in the light weights, but I'm simply talking about holding together until impact.

Thanks in advance!

I have a 220 swift in the Ruger VT. I have topped out at 4450fps with H-380 and the 40g BT. Amazing terminal performance on jacks and pdogs.
4300fps with the 50g CTBT and H-380. With the 55g I have gotten 3950fps with a stiff load of IMR-4064. I have not tested any 60g bullets due to the 1 in 14" twist, I was worried it would not stabilize the 60g V-max. The best all around load I have found for longer range work out to 600 yards, would be the 55g at 3900fps.
