Input please. .270 WSM With Bullets Seated Long

MT-JONAS · Nov 29, 2024

I currently have a 6.8 Western with a variety of bullets stocked. I plan to buy a friend's Tikka T3x Stainless. I am considering rebarreling the Tikka to a different caliber. I'm curious if I can maintain the case dimensions of the .270 WSM but seat long bullets out long like the 6.8 western. I would order a 1/7.5 twist barrel. Are reamers, dies and components readily available for what I want to do? Any other words of wisdom?
Thanks

If you get it throated right and the magazine and action are long enough then yes you could seat bullets in the 270 just like the 6.8 Western. I don't know where or how to get it done. But it shouldn't be that difficult. Some of the barrel suppliers should be able to help you get it done.

Figure out the magazines before buying the barrel!

Look to Unknown Munitions for bottom metal.It should be a fun project.Good luck.

Like stated above chamber can be throated for bigger bullets if only SAAMI reamer available. Just make sure you have room to feed them.

I have the exact reamer you want on file at JGS reamers. Let me know and I can get you the freebore. I have a copy of the reamer print some where . P M me for more info.

All Tikka's are "long actions" even the with barrels chambered for 308 win length case. If your friends is in a WSM case (i.e. it has the right bolt face) and you want to seat extra long. You will need to buy long action magazines and change out the short action cartridge bolt stop for a long action cartridge bolt stop.

Thanks guys! Definitely helpful. The rifle is currently chambered in 30-06 Spr Fld.

You'll need a mag face bolt or have yours opened up if you're going 270 WSM.

Do you feel the extra case capacity of the .270 WSM is significant? How much increased speeds over the 6.8W with the same bullet?

I've thought about doing the same thing on my T3x 270wsm. Ultimately, I haven't messed with because it shoots 140 Accubonds so well. I wholeheartedly recommend you find long action mags to take advantage of the longer/heavier bullets.

MT-JONAS · Nov 29, 2024

You guys have been great!
So my custom 6.8 western has a 1/8 twist barrel and shoots the 155/160 class bullets with great accuracy. In your estimation, what's the longest/heaviest copper bullets a 1/7.5 twist will stabilize? Current bullets or those potentially still to come, 170? 175?

Also, will there be decreased bullet speeds or higher pressures with faster twist barrels?

sedancowboy · Nov 29, 2024

You can easily shoot Berger 170 EH in a 1/8 Twist.
I would think a 160 gr Hammer Hunter Tipped would be a great Mono hunting bullet and it will stabilize in a 1/8 twist.

As WeserBucks stated, you'll need a magnum bolt before moving forward. That or build a 270 Win throated long. Probably get some impressive numbers with that as well. Plus no need for another bolt.
