6mm Rem AI with 105 gr. heavier bullets?

[Plumsask]

So I had put together a 6mm Rem AI a few years ago and it's been wonderfully accurate and has taken antelope, whatitetail, mulie and over 100 coyotes. It's a 1:8 twist S7 shillen. I built it on a shirt action and that was my only issue as I could use the heavier sleek and VLD style bullets. I had settled on the Sierra 90 Gr TGK using 53.0 great of H4831sc and a Fed210. It produced 3500 FPS and a low ES/SD. Maybe I should have left it alone but I couldn't. I found a long action and a good HS stock and did the trigger in it. Headspaced it identical to its previous set up. Now I'm ready to try some 105's. I have some scenarios and 105 hunting VLD. I have thought about the 115 hunting VLDs but berger shows marginal stability....still may be worth a try. Anyone have experience with the heavier bullets 105+ in the 6AI? powder recommendations? 26" barrel...any velocity expectations?

Thanks

I’m interested also.
I sold my 6mmAI, it was a 12 twist and was a heavy varmint rifle. I recently had my 240 Weatherby re barreled with a 7.5 twist Krieger to shoot the heavier bullets. Only getting started, I killed a medium sized buck and a small mangey fox. Bullet performance was excellent on the deer but the fox(on this occasion) didn’t offer enough resistance for the bullet to open up. I did pick up a couple boxes of those 90 grain Sierra TGK. How did they perform on game?

Antelope was Down and dead on the spot with the TGK at 276 yards. A whitetail doe at 366 yards didn't even get up out of her bed....all a saw was her head flop over when I got back on target after the shot. My wife also took two does (whitetail) this past fall. One at 225 yards bedded, it also never got up out of its bed and the last one she hit low in the bottom of the chest at 250 yards and it made it 30 yards and piled up. For coyotes........if you done put it well behind the shoulder or hit a spine or too low.....or quartering.........it's sometimes softball sized exits. But I've never had a runner.

Forgot to mention that I was using the 105 Berger hunting VLD with the deer and fox. The deer was hit broadside and left an exit hole about 2” or more in diameter. I haven’t run it over the chrono, the shot was only about 120 yards so I suspect the velocity was still fairly high.
