Re: matching the performance of factory weatherby ammo

a lot of the rated velocities of weatherby ammo is hyped up, butthe 87 and 100grn Hornady loads aren't, sometimes they are faster than listed. I have or have had all three weatherby cartridges that you speak of and in a 26" or longer barrel you can out run and out group weatherby ammo but brass life is 3 to 4 firings. I used to shoot the 100 grain Hornady right at 3900fps with RE25 and thats a mean load on a hundred pound whitetail!

Case life has never been a problem for me. I usually get 15-20 or more reloads from each case. I have a buddy that was a manager in load development for hornady for many years. I would caution about pushing a 100g to 3900fps. He would start blowing primers over 3750 and rupturing cases over 3800 in lab controlled barrels.

Hell your right, i'd simply caution anyone about using hornady brass! With RE25 I'm only .5grns over max to get that velocity. In all but one batch of 6.5x284 brass, Hornady brass has proved to be extremely soft, needs way to much prep, and is simply GARBAGE!

Are you getting the 3900 speeds out of a .257 weatherby? Those speeds are 3-400fps over any loading manual for 100g.

Re: matching the performance of factory weatherby ammo

Re 22 at 72.5 gr and 100 gr bullets will get you right at 3800 out of a 26" tube. Worked up loads in 3 Remington 257 Roy's and all of them shoots this load around 1/2". One of he guns had a sticky bolt so I replaced the 215 primers with cci benchrest and no more problems and groups stayed the same but velocity dropped 30 fps.

Yeah 75.5grns RE25, rem 700 lss mountain rifle in 257 roy, the previous posters load of 72.5grns of RE22 is hotter than what I load, I'm not even flattening primers, and could get 7 or 8 loads if I tighten the pockets. Published data does wants to make the 25-06 look more impressive than it is when compared to the wby.

Re: matching the performance of factory weatherby ammo

any of yall running h1000 in your 257wbys? i just ordered a reloader for christmas and everything to load for my 257. i have been having a friend load my 7mm and we are at 73.5gr h1000 pushing 150gr ttsx. i ordered some 110gr accubonds for the 257 and i am just curious where i might start with the h1000 in it.

about the wby factory loads vs hornady. when i got this rifle the only thing the local shop had for it was some of the round nose 117gr so i zero'd it with those advertised at 3450fps. after shooting that box up i switched to 110gr interbonds from hornady custom advertised at 3330fps. i had to bring my zero down 4 moa at 100y with the hornadys.
