Should I build a 25BRA or 25 Dasher Varmint Rifle? (Decided on 25x45AI)

[AllThingsAI]

25x45AI....nearly complete! Look at this monster with 70g Sierra Blitzking

Ok...I’ve decided on my next rifle. I really appreciate all the input!

Winner is: 25x45AI
Runner-Up: 25PPC (will build a bolt body and barrel at some point)
(Ended up in a totally different place than where I started ][stuff deleted]

Interesting choice but I seriously doubt that this will meet your original specification of a cartridge “capable of 600” - especially with the 70gr sierra. Sierra publishes pretty accurate BC data so model it in your favorite ballistic app.

Oh it will shoot 600...just might have to shoot rainbows!

True! But modern laser rangefinders and ballistic apps can solve that. Was thinking more about wind sensitivity...

Honestly I won’t shoot this one much beyond 200...wouldn’t pick a flat base bullet for 600. Should be extremely accurate out to 200 or so.

I bet the 90gn Blitzking would make it to 600 with energy to spare. Looking forward to updates!

It’s mild. I shoot 110 BIB bullets, they shoot so well that that’s all I shoot. Plus Randy was very helpful as far as quarter bore info goes. Easy to form, easy to shoot, brass is Easy to find and lasts a long time. Speaking of Randy (owner of BIB bullets), he’s shot the 25x47L a lot and would be a great source of info, I talked to him once and learned more in 5 minutes than a week on the internet.

What is twist on your 25x47 pls?

All, I’m looking for opinions on my next build. My last rifle was a 6x45AI and I absolutely love it. I did a lot of homework before I built it and I would like to do the same here.

I’m thinking of moving from 6mm to .25 cal. It seems to me like the larger diameter bullets are more explosive and have a greater initial impact than the smaller cals (just my observation). I’ve shot .17, .20. .22, and 6mm. I’m thinking of a 25BRA or a 25 Dasher. I have 6mm reamers for both so I can make it work by reaming out the neck diameter and purchasing a .25 cal throater.

What are the pros and cons of of each and what do you think of .25cal...looking at 70g SBKs. I’ve never had a .25 cal before so I don’t know it’s accuracy characteristics.

Small varmint gun capable of 600 yds or so is the goal. Accurate AND flat shooting with low recoil to spot shots...but doesn’t need to be a barrel burner. Huge fan of Ackley chamberings.

Your wisdom is appreciated.

Keep it simple. How about a 6BRX. I have one. Shoots a 60 gr bullet to at least 3700 fps. Don't believe bigger are more explosive. I think it depends mostly on bullet construction and how fast it's going. 25 caliber, now your talking about deer size cartridges for small varmints.
