I am a big quarter bore fan myself. I had a .250AI (.250-3000 Savage Ackley Imp 40*) for 10 years and a .25-06AI for 11 years. Back before any heavies were available. Both had a 1:10" twist.
The 23" .250AI shot a 100SMK, 100 NBT, or 100 TSX @ 3200. Or a 115 VLD @ 3050.
The 28" .25-06AI would run a 100 TTSX @ 3600, or a 115 VLD @ 3600. Deer zapper.
I rebarreled the .250AI to 6.5SLR when my younger daughter started shooting.
I rebarreled the .25-06AI @ 800 rounds to .280AI after that barrel was toast.
Then the fast twist/heavy for caliber 131 BJ came out...and I was hooked again on the .257s.
Now, I have a few more .25s again.
26" 1:7.5" 25SST was my first. 133 @ 3240fps 11.5# scoped and suppressed.
26" 1:7" 25CM Hunter, 133 @ 3001fps now that it has sped up (the 400MODBB barrel took about 350 rounds to finally speed up) About 10lbs
26" 1:7.5" 25CM Target, 135 @ 2986fps, 14.75# scoped and suppressed.
22" 1:7.75" 25PRC/SI. 135 @ 3150-3200+ (still fire forming brass and just started load development with formed brass) This will be a dedicated shorter/lightweight deer/pronghorn rifle once I get a load worked up, for ranges out to about 1200 (capable, but probably not stretched that far out). Right at 9 lbs scoped and suppressed.
Coming soon:
22" 1:7.5" 25MBK. This reamer just came in this week, and all the parts are down at Axisworks for the build. Dropping off the reamer this morning to get it built. I am hoping for the 133s to be around 3000 from the 22" barrel. I think it should be possible. This will be a lightweight short hunter for deer-sized game at medium range (out to 900-1000ish?). Should be about 9-9.25lbs scoped and suppressed.
