108gr JLK bullets

[lewie36]

can anyone tell me what twist it will take to stabilize a 108gr .25 cal bullet in a 25-06? will a 1/14 do it? 1/12?

It's going to take a lot more than that I think. 1:9.5 I believe is the correct
twist for that bullet weight and about all bullets. Just looked up a stat, 1.19
inch bullet is about max for a 1:10.

A 1-10 will stabilize up to a 130 grn uld bullet.Trust me
a 1-12 will do the 108 grn just fine.

A 1-10 will stabilize up to a 130 grn uld bullet,it is 1.345" long.A 1-9 will stabilize up to a 142 grn uld bullet and a 1-8 will stabilize a 156 grn bullet.These are @3000 fps.
a 1-12 will do the 108 grn just fine.

Don't know if I have ever seen a 130 grain 25 cal bullet but no reason one
can't be made. Here is a link to a barnes 115 grain tsx,

New bullets are getting longer, old twist rate ideas have to give way to what is
now on the market. We are seeing lead banned in more places as time goes
on.

Of coarse you don't have to take my word for it.

The 130 was a very good bullet and with a stiff load of Reloader 25,3011 fps was obtained as a safe hunting load out of a 25-06 with a 26" 1-10 twist barrel .The 156 grn bullet was something to behold, with a BC of .820 and a velocity of 3368 fps.This was pushed out of a .338 ultra necked down and blown out.That was just plain wicked!!!!!A lot of guys used the 142 grn in .257 Weatherby's,25-06AI,and the .257 stw but 9 twists were needed.

Bigwheeler,I certainly don't mean any disrespect to you in any way, however neither Swampy or Barnes have ever fooled with bullets of this weight in 25 cal.I have to admit I was surprised to see the results as well as the green hill formula had called for a much faster twist than was needed
all the best

I wil not be able to get any till spring. So I will look into a good 100gr. for now. i sent you a pm wolfhunter.

 

[bigwheeler]

Thanks Wolfhunter, I haven't ever seen those long bullets in .257 .

Lewie did you place an order with JLK for those bullets? I was wondering how long it took to get them from time of your order till shipment.

I've been shooting the 100 grain Sierra matchking they shoot very well, but I was still interested in the 108.

 

[lewie36]

Not yet but he said I would not receive them until spring if I did.

I did the reading on the long wildcat bullets wolfhunter suggested and the
guy is shooting 1:10 and 1:8 barrels. I still will stick with JLKs website that
gives a specific note on the 108 that you need a 1:10 twist. You are not going
to stabilize them in a 1:12. There is no magic to it.
