257 SAUM Reamer?

[DLJ6]

Gang,
Ive got my mind set on a 25 SAUM project for 2025 and have already started collecting components. As of now I am thinking of using a Kauger VPR SA and a HCA 7 twist barrel finished to around 22".
Ive done a couple of searches but not turning up reamer options. Does anyone know sources for a reamer?
Any assistance is greatly appreciated.

Thanks blaster, I will gladly comp you a rental fee. What COAL , CBTO are you running and have you tried any of the newer 130 class bullets in your rifle?

I don't have a 25 SAUM, but I do have a 26" 25SST and 22" 25PRC/SI.

Your twist rate is good. You could go to a 1:7.5" and still be fine.

I have tried most of the newer heavies. 131 Sierra Match King
133 Berger Elite
135 LR Hybrid
138 A-Tip

I haven't tried the 134 ELD-M yet.

My final loads are as follows:
26" 25SST 133 @ 3311fps over H1000
22" 25PRC/SI 133 3212fps over RL23

You should make 3100-3200+ with the 25SAUM in a 22" depending on bullet and powder combo.

Thanks Lance.
Whose barrels are you running and did you build both on the same action, Bdl or detach box?

25SST is a Proof on a Kelbly Atlas Tac. DBM in a Manners EH1

25PRC/SI is a Benchmark on a Kelbly Atlas Lite, Hawkins Hunter DBM

These are all 6.5 versions, but show case sizes.
PRC, PRC/SI, SS, SAUM

SST, SS, SAUM, PRC, PRC/SI, WSM

Thanks much. Yeh it was a toss up for me since I also shoot 300 SAUM and 6.5 PRC and have quality brass for both but a friend / member here offered me a good deal on a set of Redding 25 SAUM dies.

Great reason to build a new rifle!

Heck, I had a spare BixN Andy Tac Sport Pro trigger in my safe, and had to build a whole new rifle just to use it!
