Heaviest .25 caliber bullet?

[GOT]

I'm just curious as to what the heaviest .25 caliber bullet there is (its the .257).

Thinking about reloading for the .25 wssm and wondered what the max bullet would be. Currently factory loads top out at 120 grains. Are there heavier bullets?

I've never heard of on heavier than 120 but I guess you could have them custom made. A 120 is a pretty long bullet in 25 cal. Are you looking for long range stuff like the 80 grain 224's?

I have a .258 super condor( .300H&H IMProved and necked to .25) which has a 1-7.5" twist. It came with some custom 200 grain bullets and some 160 grain bullets . Note these bullets were custom made by Sisk bukket company in early/mid 50's!!! I have to use 120grain new bullets in it as they are the heaviest available. The 'quick twist' craze reached its apogee in mid late 50's, and disappeared until some guys started fooling with heavy .22's in last 5 or so years.

on www.baitshopboyz.com/forum one of the members (custom rifle builder) twisted somebodys arm enough to push out 145 grain bullets. unreal sd's and bc's. not sure if the 25-06 has enough pop to it to take advantage of the extreme bc's or not, but 257 roy and stw users should be pretty happy.

"200 grain", wow.

Griz, I'm just curious to know what its potential would be as a big game cartridge. I did see in some reloading book (at BN today) that there have been 125 grain bullets made, but it was only one company (don't recall the company... it was a small one). I've also been wondering about its potential as a combat round (having just read a lot about the 6.8 Rem, which uses a 115gr bullet for potential combat). It would fit in an AR mag, from what I know (the .25wssm's over all lenth is 2.36").

I have a 257 Roberts Ackley Improved built on a VZ24 action with a 1 in 10" twist Lothar Walther barrel with varmint taper:

Anyway, that rifle shoots .5" groups with 72 or 75 gr bullets, but not so good with 87 gr, and 1.5" groups with 110 gr bullets.

The heavy bullet point of impact is an inch to the left.

I have been avoiding the heavy bullets.
I can get 3900 fps with the 75 gr, and except for the noise, the gun is perfect that way.

The Quickload 257 bullet library only goes up to the Remington 122 gr.

If big game is the goal I would think that something like the heaviest Barnes X bullet would be the best bet. (Don't know if it's a 115 or 120) That would expand at any reasonable range, penatrate very well, and is easy to find so you don't have to scrimp on zeroing and practice rounds.

If you are interested in really big game like moose I have no idea how it would work. And I have even less knowledge about combat rounds.

Its a tad over .25 cal. But, the 6.5 swede (264) standard military load is in the area of 140 grains. I THINK i have seen factory ammo as high as 160 and i've heard of handloads up to 180grains (IIRC).

I have a friend who has been shooting deer for over 40 years with 257R, 270, 7.62x54. and 300 Win mag, and he tells me that the 100 gr 257 Roberts is the only cartidge that has never allowed the deer to take another step.

I have always thought that must be because he aims it better.

I wish berger and JLK would make .25 cal VLD's that would bridge the gap between 6 and 6.5 mm.
