257 weatherby mag

I know this has been talked about numerous times but I could not get a consensus on what I am thinking about what I want to reload in my new Remington 700 LSS 257 Weatherby Mag.

I've broken in the barrel with the cheap Weatherby Ammunition 257 Weatherby Magnum 100 Grain Norma Spitzer and now have a few boxes of once fired cases to use to reload.

I've gotten a box of of Berger VLD 115 gr. and a box of Scirocco II 100 gr. from a member here and I am going to purchase Nosler Accubonds 110 gr. and Barnes TTSX 100 gr.

For powder I've used in the past when reloading for a 300 weatherby I really liked H1000 and IMR 4350. I am also thinking about for other options of powders getting some Retumbo, RL 25, IMR 4831 and IMR 7828.

For primers I want to use Federal #215 Large Mag.

I want to try the Scirocco II, Berger, Accubond and the TTSX in the rifle.

Des anyone have a load/powder that works best with these bullets?

I mainly will be shooting whitetails and paper with these.

TIA

Re: 257 weatherby mag

In my Accumark 257 Wby

I like H4350 powder with the Barnes TTSX 80 grain Bullet

I suggest to stick with a controlled expansion Bullet in the 257 WBY to avoid meat loss.

Expect exit holes in small TX deer that will take alot of meat with the Bergers VLD 115gr.

Suggest get a Neck sizer die for your brass once U shot thru Your rifle it will make your cases last longer.

For TX Whitetails the 80gr Barnes TTSX would kill like instant and very Flat shooting


I like H4350 with the 80 gr Pills using Fed 215GM Primers in WBY cases and trim to 2.539"

I use the 100gr TTSX over 71gr of RL-22. This load is very accurate and chronys at 3590 out of a 26"bbl. I have tried 7828 and RL-25 but keep going back to RL-22.

Re: 257 weatherby mag

Thanks for the info.

Does anyone else have a load for bergers, scirocco II or accubonds?

And does anyone use Retumbo powder with the 257 weatherby?

Thanks!

Re: 257 weatherby mag

Retumbo might work with the heaviest bullets in the 257 WBY as well as Reloader 25.

I have very good luck with Reloader 22 in the 257 WBY.

With the 110 AB's and 115 VLD's I have used 19, 22, and H1000 so far. All with great results.

My brothers rem in 257 roy thrived with I 7828. I don't normally promote that powder, but it really loved the powder and delivered both accuracy and velocity very well.
