The .257 Marksman (25 western)

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.
