Re: Need help 257 wby berger vld

Be sure to retain some freebore if you do have your own weatherby reamer made. If you make it short enough to be able to put a bullet into the rifling you had better label the barrel just in case some tries to put factory ammo into it. Could build high pressure.

Here is a chart I got from weatherby's website:


What is the throat length (free bore) on your Weatherby® rifles chambered for Weatherby® magnum calibers?




Cartridge Throat length (free bore)
.224 Weatherby Magnum .162
.240 Weatherby Magnum .169
.257 Weatherby Magnum .378
.270 Weatherby Magnum .378
7MM Weatherby Magnum .378
.300 Weatherby Magnum .361
.340 Weatherby Magnum .373
.375 Weatherby Magnum .373
.378 Weatherby Magnum .756
.416 Weatherby Magnum .239
.460 Weatherby Magnum .756
.30-378 Weatherby Magnum .361
.338-378 Weatherby Magnum .361

Or you could just load up some 115 Nosler BT over a full charge of H-1000 to 3.330 or 3.305 OAL. It will shoot 3 shot groups into 5/8" at 200 if I do my part.

I have used this combo for years and killed alot of critters way out there. I have even shot whitetails in the woods at 50 yrds with this load as they came in behind me while covering a field. I was surprised it didn't 'blow it up'. Nosler redid the jackets on BT's years ago and got it right. I have taken big bull caribou with this load at 350+ broke both shoulders and spine the bullet was under skin off shoulder separated. That's through 2 shoulders and spine a fair amount of bone. So the bullet didn't 'fail' or I wouldn't have been able to recover it, just very lethal.

Everything I have shot with this load died with one shot. I shoot a Wthrby rifle actually a few of 'em.

Sorry I have never tried the VLD's figured I would just share what works for me.

Re: Need help 257 wby berger vld

Thanks guys there is a lot of good info here. I finally got my 100 gr swift load fine tuned today. Now I will start in on the bergers to see if they are any better but they're gonna have to shoot pretty good to best the swifts. I will post a new thread to not get this one off track but 3700 ave with .75" groups and under at 100 has me smilin. I will update again when I get berger data.

Thanks

I don't remember what powder you said if you said you were using, but I know that 75.5grns of RL25 will get em over 3800fps in a 26" barrel, its a good 30-50* load but don't shoot varmints with it when its 90*, that's for 100grn pills, not 115s.
