6.5 options

[lancetkenyon]

I went with 6.5-300WSM back in 2001, I used a long action, then I looked at all of these newer options and went with 6.5x47 (2) and 260AI.
Not a single animal knows the difference, even when I'm using my 264WM or 6.5-300 Weatherby.

Choose whichever one you like the most.
I never let anyone else sway my choice. Choose a barrel length and build it.

Cheers.

Nice!
6.5mm is my favorite caliber, with .257 a close 2nd.

I have six 6.5mms:
6.5SLR
.260AI x2
6.5SS x2
6.5PRC/SI

@lancetkenyon
My favourite is, and always has been 25 cal, it is so underestimated it simply defies book ballistics.
I have:
257AI.
25-06 (3).
25-300WSM (Pronghorn) (2)
257 Weatherby (factory Accumark) & another blank with 8.5" twist, still can't find a 7.5" or 7" twist blank here. Looking at doing a 25-300 Weatherby…
6.5mm is a very close second for me, but 30 cal outshines it with number of rifles I have.

Cheers.

A speedy 257 bullet of the correct construction does things greater than it "should" for certain. Said it before, I'll say it again.
It's also a true dual purpose. And great both ways.

I've only had 4 different ones.
25/06
25/06AI
25 Sherman LA
25 Sherman Short

I suspect a Sherman Max may be next. Dude borrowed my reamer and won't send it back.

For 257s:
Long before the heavies came out:
Had a 25-06AI I shot out
Had a 250AI

Now:
25CM x2
25MBK
25SST
25PRC/SI

What is the 25MBK?
Is that a true SA cartridge?
Looking at something 25 to go into my custom trued Rem 700 VSSF II switch barrel. I have a 3.15" mag box.

Cheers.

6.5 prc if you don't reload, saum if you do. Best wishes

25 "Man Bun Killer" (as in Creedmoor Killer)
True SA cartridge.
25-260AI with some tweaks.
OAL @ lands just under 2.980" w. 131 SMKs and 135 LRHT. 133s are a touch shorter.

So, I could run my 260AI brass into 25 cal…. Never thought of that tbh. I was thinking 250AI a few years back.
What twist you running with that?
I can only get 8" or 8.5" twist currently, wanting 7" twist.

Cheers.

I use my .260AI FL bushing die and neck down. That was my tweaks to the reamer design. JGS had a "25-308 Imp 40°" reamer, but it was way different than the ".260 Rem Imp 40°" reamer in the body dimensions. WAY off. So I worked with them to make the body/ahoulder exactly to the 260 reamer, and then altered the neck/FB/leade to match the 25CM BJ2 design. I am very pleased with the outcome.

My goal was to match my two 26" 25CM velocities (2976 & 2985fps), but in a 22" barrel.

I have surpassed those speeds. With only 50 pieces fire formed, I loaded up 15 rounds in once fired brass to see where speeds might end up. I hit 3044fps with the 131 SMK on shot #65 down the barrel and no pressure.

Thanks. Sounds exactly like what I'm looking for. I will look into this a little deeper and design a reamer.

Cheers.
