25 cal barrel just arrived. What would you build?

Too me it would be something to play with

I have no problem with one bullet manufacturer for the 145 or one manufacturer for the 163 and 180, and I do not care if these bullet weights are the wave of the future or not. They made it available, so I am giving it a try. I have plenty of .25 cal bullets from 115 to 135, and .25 cal is not the only caliber in my inventory to play with. Your intended purpose is not the same as mine, and what is fruitful to you is not the same as mine.

My intended purpose is to carry as much energy as far out as possible and not have to spin the elevation dial 3 full revolutions to get to 1000yards. My purpose and yours are probably similar on that aspect.

I'm honestly curious about how this 163 and 180 are going to be better than a 135-145. The 163 and 180 are a solid copper bullet? What is the OAL of the 163? Are you running these in a sub sonic type fashion?

Get you an efficient 85+ gr case, super fast twist and long "as you can stand it"barrel, for best results.
26" minimum for that powder charge, and tight tunnel.
28+ probably optimum. Like 30" will not be excessive



Give er hell!

I stopped my pressure test with the 145 (with MagPro) when the 163s came up. I can probably push it past 3200 FPS with H1000, Retumbo, etc.

No, they are not solid copper. As noted in #90, I pushed the 163 at 2915 FPS on my last pressure test with more room to spare.

@Justice1327, my sincere apologies for this sidetrack.

If anyone has any questions on my .257 WBY, 145 BH, or 163 Chinchaga PM me and I will get back with you ASAP.

You were keyholeing 163gr bullets at with a 7.5tw at 3000fps?

Yes, I got one out of a six shot group that keyhole. First time ever experiencing this.

 

[Bghunter338]

Who's making 150-155's BGH338?

You are at 26" right?

Yes 26". I'm trying to talk Dale in to making me some. I feel that whole be the max weight for the 7.5 twist.

 

[Phil Rizzo]

Sounds practical.
That Blackbird may turn into a Peregrine Falcon!
Your case is what, 83-85 grs?
