270 barrel swap

[Sunglorider]

I've got a remington 270 that's getting long in the tooth been knocking around the ideal about a rebarrel .I don't know if I will keep the same caliber or change out to something else .what would be a good starting point of calibers to consider if I change

If you are a reloader, go with 280AI. If you want to stay with factory ammo, stay with 270, but go with a faster twist (1 in 8) to give you the option of shooting the 170 Bergers if you later decide to load your own.

I don't reload yet ..but planning to in the near future. How will the 1x8 twist do with the 145 or 150's

You can't beat the value of the e.r. shaw kit for the savage 110. The .270's recoil is substantially less than the .30-06 in my opinion so that would be a great choice for you. Not sure if they offer a .25-06 kit (they do stock the barrel at midway) but you may want to look into that as well. It would be a bit more money but you could get the go/no go guages and barrel nut wrench separately if you needed to.

I have not personally loaded for the .270 and the .270 shooters I know personally tend to be shooters of factory ammo. Anything I might say regarding your question would be pure conjecture on my part. Probably not particularly useful.

Most folks loading the Berger 170's tend to be 270 WSM shooters. After looking around a bit, I have yet to encounter a discussion involving shooting lighter bullets in a fast twist .270 of any flavor.

I did spend some time on the Berger Twist Rate Calculator. Depending upon the altitude where you plan to shoot/hunt, it does seem that going to an 8.5 twist might help you hedge your bets if you are concerned about performance with a broader range of bullet weights.

That's about all I've got...

I did this exact thing to my old Remington 700 .270 this past winter. I am a reloader and don't use factory stuff in anything but my .22 long rifles haha. I went with the .284 Winchester with the Norma Match reamer that has a long freebore for 175-180gr bullets. It's a hammer and uses the same powders and similar charge weights as the 270 with 130-150gr bullets. My previous .270 loads were a 140gr Hornady at 2980 with 56.0gr IMR 4831 and a 145gr Hornady ELD-X at 2935FPS with 56.3gr of RL23. My .284 load is 54.2gr of RL23 with a 175 Berger at 2850FPS. The major difference is the down range energy and less wind drift over the .270 with 140-150gr bullets.

If I were you, I would lean towards the .280 Ackley. It has high quality factory ammo available, and can be handloaded for even better accuracy and performance if you plan to do that. It also works with your action and bolt without any modifications or changes needed.

Im Im running an 8.5 twist in my 270 ss and it handles the 170 eol well.
It will run 2950' with a 21" barrel.

There is no down side to a 1/8 twist in a 270 it will work just fine with the 130-150 class bullets as well as stabilize the 170s. I have both and all my future 270 Wins and 270 WSMs will have a 1/8 twist.

A 270SS would be the cats meow! Shooting the 170s the 280AI would have nothing on it.

The long time 270 130gr recipe was 60grains of 4831 a 215 in winny brass seated longer. I was 3050ishfps in a 22" gun for many. Now I'm running Rl 26 with the 140 game changer @ 3140. This in a 24" vangard stock. Shoots very well has shot sub 3/4moa since day one. Many times much better.
It will run faster but not as accurate. The 130grn loads have run over 3200fps but ironically everything you look for sd, es, and group come together at 3140fps also with Rl26. In a 3 shot group 4 different days es sub 5fps usually 3fps and once it shot the first 3 at 3139. This in a thin factory barrel.

Why not do 270 Sherman.
