.270win Rebarrel

[Slim01]

I'm going to rebarrel my .270win. It currently has a 20" barrel with a 1:10" twist. It will be used with lead and monoliths for plains game and deer out to 300 yards max. What length and twist rate would be best? Thanks.

Generally speaking 1:10 and a 24” barrel are “standard” for a 270… some like a tighter twist for heavier bullets.. and some like a shorter barrel for mobility..

For me a 1:10 with a 22” is about ideal..

If you go 1 in 8 you can shoot the new heavy bullets. They go up to 175 or a little higher.

With the new laws hitting the UK, it would be in your best interest to get a faster twist to shoot the mono-metal bullets. They normally shoot best in fast twist barrels and have more reliable expansion with the higher RPM.

I called the gunsmith I'll be using and he has 1:7.5" and 1:9" twists in stock but no 1:10". He's rebarrelling a lot of rifles to .270win with faster twists due to the proposed ban of lead ammunition.

i have recently re barreled my Howa 1500 270 WIN, with a Pack nor 1-9 twist bbl slightly heaver profile than original cut to 25 inch long it shoots most 130 to 150 grain bullets into less than 1 moa for 5 shots its in a HS PRECISION stock, its maybe the most consistent easy to shoot rifles i own. I going on a special deer hunt with a old army friend next week its the only rifle i will take as it shoots so well using 130 grain Hornady CX bullets in Starline brass.
