After discussion with someone with extensive experience who has tried 8s, 9s and 10s, he recommended 1:9 as the best option.
Curious if you have an update for how this barrel change went? I am also considering rebarreling my 270. I love the cartridge, but want a threaded barrel to be able to add a supressor or brake. Was very curious about the newer faster twist barrels that might be good for the 150gr ABLR.I went with a 1:8 twist, 22” carbon six barrel. Going to be taking a close look at the new Barnes LRX 155gr .277 bullets just announced, should handle nearly any situation I come across from antelope to elk? Anyone have any other good ideas on do all, fast twist bullet?
People will say [.277 is] a fudd caliber
6.5 mm is more "fudd" than .277 is...
1:10 twist barrels tend to stabilize lead projectiles up to 150gr if they're sleek and 160 grains if it's an old style round nose/flat base bullet.Is there a general "this twist for this bullet range in lead core bullets in 270 cal"? I'm assuming non lead bullets are longer to make weight.
I'm wanting to shoot elk, and also have fairly light deer and practice rounds.
Did you have the throat opened up for that, did the longer bullet require extra free bore?1-8 on my 270 stabilizes the 170 Berger with no issues. Been a fun long range twist on a classic caliber.
The reamer was made based on that combination. I made up a dummy round and sent that off for the reamer build.Did you have the throat opened up for that, did the longer bullet require extra free bore?
OAL with the Berger 170 is 3.520” with 0.025” of jump. Absolutely no issues with feeding through a standard mag box and follower. It’s been an easy cartridge so far. My hunting partner built one as well with similar results. I can share load data if desired.@BDWMT What col do those 170’s come out to? Any issues with magazine length and feeding?
