What are the heaviest bullets a 9.5 twist in a 26 inch barrel stabilise in a 7mm rem mag. The rifle will be used for long range shooting both hunting and target
I had a 7 Mag that would keyhole 175 grain Sierra factory loads from Federal. I reloaded the brass to a little higher velocity and they stabilized. Apparently they were on the ragged edge of stability with at factory 9 1/2 twist.
3000ft plus After a long exhaustive search I narrowed down to 4 manufacturers. Sako, browning and weatherby all offer 9.5 twist Remington does 9.25 But it is my last choice. I like the 155 to 175 grain range. Hornady eld-x has a 162 grain offering with a whopping 615 bc another is a Berger vld in 168 gr. Also like the various lead free offerings in 150 to 165 grain range
Berger hunting hybrid or whatever they call it in 168 should do fine. My 9.5 twist does well with 180 scenars at 6500 elev. Its a Ruger. It shot the 168 bergers well too. I did not have good luck with the 168 vld.
Mine's an 8 twist Brux and it'll shoot 180 gr. VLD's as well as, if not better than 168's. I haven't tried the LRX in that gun, but wouldn't bet against it shooting really well.
With your gun, you'll have to find out its limit and stick with it. The top weight will depend on bullet type.
The NPT is always a good hunting bullet, flat based and not overly long for weight. See how heavy a Partition it will tolerate.
Many thanks for your informative replies. I would appreciate recommendations on factory rifles with twist rates faster than 9.5. To date the fastest I am aware of is Remington with a 9.25 all the rest I have come across are 9.5
