6x45 1in7" running above 95gr Bullets

[EOD Rob]

So I did a search to see if anyone out there was running anything above a 95gr 6mm in a 6x45 and found nothing. This might be answering the question right off the bat, but here we go.
Working on a Savage 12FV build in 6x45. The barrel is an X-Caliber 22" 1in7"twist. Was wanting to know if anyone else is running that fast of a twist and what bullets they are running. Also, am I gaining anything with moving up to 100gr-105gr bullets.
If you are, would you please share your load ups with me? It would be nice to have a starting point.
Thanks in advice for any and all advise.
Rob

I had a 27" 1-8" 6x45. It shot great. I shot a lot of 95SMK's out of it. In a 22" barrel your not going to get a lot of speed so I think you'll be fine as far as blowing bullets up. Some of the varmint bullets might not live but you'll just have to give it a try. I think anything heavier than 95gr is going to go so slow you'll be well into dismissing returns. Hodgdon Ball C2, Varget and 4895 all shot well. I sold that rifle and don't have data for it anymore.

Thanks for the advice swd!

I have a 6x45 24" 1:7.5 Green Mountain AR w/+2" gas system. I shoot 107 SMKs and 105 Lapua Scenars (single loading). Brass is Lapua (neck turned), loaded 0.010 to 0.030" back of the lands. I think it's best to run a slower powder in the Varget range and start at about 24.5 gr. With Varget at 25.5 gr I get good groups w/MV about 2625 fps. At 26 gr it's up to 2650 fps, but that load is a bit too warm (extractor swipes, and opened up quite a few expensive primer pockets). With a case full of Varget it's a tight fit, loading the longer bullets (very compressed loads). I've also loaded up H4895...you have to back down a few grains since it is a faster powder, but it takes up less case volume and packs a bit down better via a drop tube. You won't get bolt gun MVs but it depends on what you are using it for.

I have a 1:7.5 on a Savage I tried 107's with just around 23-24 gr. of IMR 4895, never ran over the chrono but it shot nickel size groups at 100, but shot much better with 95 gr. dime sized.
