Any word on twist rate?

Here is some history on my use of the 110 gr Speer Varminter in 30-06.

We initially loaded the first 100 in the '06 with a decent load of 3031 for an expected velocity around 3500 fps, just like I had successfully loaded 110 gr RN in the past. I took a shot at 100 yds, and missed the target clean. Walked up to fifty yds, still a complete miss. Thirty yards, complete miss, not a mark on the18 inch square target. WTF?????

This was in about 1980, and I had only been loading about a year, I was pretty much a novice.

So anyway, the next shot at fifteen yds left six or seven holes in the target. The bullet was fragmenting near the muzzle due to excessive RPM.

I slowed it sown to 2400 fps with 4198 and used that load for years on ground squirrels, musk rats, and pop cans. It was about a two moa load and I used it out to about 150 yd targets. If you could hit the water with it about 12 inches this side of a muskrat, it would lift the rodent about six feet into the air and drop him dead without a mark on his body. There was zero chance of a ricochet from the water's surface, not that it would have mattered on that muskrat infested reservoir. There was nothing down range, but a cheat grass bluff.

But this was in a commercial Winchester barrel intended to stabilize bullets up to 220 gr. I would be curious what could be done with the same bullet twisted 1 in 24".
