I tend to believe a 12 or 14 twist is fine for 35cal rifles. The 16t that Remington used is a bit slow for the bullet weights (length) we like. So far, I have no issue stabilizing 280s @ 1900fps with a 14t, though I could see a 10t if 300+gr subsonics were planned.

Most of my experience over the last 35yrs has been with 225/250gr bullets in the 35WAI and they shoot quite well, even the old discontinued 250gr XBT. The also discontinued 225gr Nosler BT shoots well and is excellent deer medicine. Notice a trend? The 35cal bullets just don't sell as well as 30 and 338cals and the manufacturers drop them for the latest internet hotness. As usual, my ubiquitous statement of "if you find something that works, stock up" applies.

Will throw in a link to Hawk bullets; they are priceless to those wanting to shoot jacketed in various obsolete cartridges - and you can even spec jacket thickness to suit your velocity.
