The .257 Marksman (25 western)

[sierracharlie338]

Do it! Lol
It would be really cool to have more than just my data.

From what I've seen so far it's exactly what I wanted. If the barrel speeds up 50fps and I'm sitting at 3200 I'd say mission accomplished.

But realistically this is all doable with the 25-7 prc, just not in a short action.

Or like @hereinaz said similar to the 25sst, although maybe a bit faster? But then your into the Sherman dies and brass.

Hell I’d be tickled pink to be running at 3100 in a 20 inch barrel with 134s. Depending on how the rest of this year goes and the first couple weeks of Jan I may be getting a barrel spun up.

Are you a tikka or a 700 clone guy? I'm thinking 700 but can't remember?

Start buying more pink, cause you are gonna get tickled.

Was a 700 guy for years. Started playing with the tikkas thanks to this place so either/or I guess at this point lol.

My wife unintentionally put me in a predicament this year after killing her first deer with my 25cm. She thinks she should get to keep it now!

So I have to decide where to go from there moving rifles around or building.

Looks like the Eld-m's are shooting a little better than the Bergers which surprised me.
I did break position between 3 shot groups. And had a lot of mirage coming off the suppressor.
I think when the barrel settles in and I use fire formed brass I will be able to tighten it up a bit.

Any idea what case capacity is when necked to .257 I'm guessing it's just a sliver over what the 25 SAUM is and a little under what a 25 WSM would be.

My ADG 6.5 SAUM brass necked down to .257 holds exactly 73gr H2O.

I just got my ADG 270 WSM brass yesterday afternoon so I haven't had a chance to neck it to .257 and measure the case capacity but just guessing I think it'll hold around 79gr H2O but I'll know for sure here in a little while.

76.4 gr H20 ADG

Things are looking good with the 134's

Retumbo went 3220 at 67gr without any visible pressure or heavy bolt lift on virgin brass... definitely worth looking at. Accuracy potential is there too. This was 64-67gr in 1 grain increments

I have a 6.5 SAUM Improved that’s pushing 130 Terminal Ascents at 3250 with a 21” barrel.

I’m seriously considering having a barrel spun up for it in 25SAUM Improved.

It’s built on a Pierce SkeleTi action and the load port is long enough to run the UM short action BDM and still fit 3.150” in the magazine.

.25 is sweet, and you can keep much the same performance with a shorter barrel or cook it up faster. That 6.5 has to hammer critters.

What bullet would you shoot?
