Range day 257wby

[CAhunter]

Went out today to retest a load I worked up and shot on Sunday. It was pretty windy so I didn't chrony the load yet. Pretty happy with the results of the 2nd load ever fired from the rifle.

70gr rl25
115gr nbt
nosler brass
Fed 215M

You certainly have that load dialed in. That is fine accuracy.

 

[widgeon]

Great shooting. That is an awesome group.

70 grains of powder for a .25? I guess that is 100 rounds/lb, but WOW.

 

[Guy Miner]

Not bad at all...

I'll be interested in your velocity figures when you get them.

Nice shooting!

 

[6mm Remington]

Load work is done my friend! You just cannot better perfection!

Nice shooting! A 257Bee is on my short list. A 110 at 3500fps - what's not to love about that!

[ScreaminEagle]

Awesome!

 

[nitis]

Nice work!

If I had not had so much luck with my RL22 and the 110 AB I would try this

Just curious what your overall length is I am going to guess 3.16?

And how about a pic of the rifle!

 

[Woodycreek]

Very nice! It would be hard to pass up the 257 Bee if I get into the quarter bores.

Thanks guys. It sure is fun to shoot. I did edit my load data Fotis so pressure should be fine.

 

[FOTIS]

Just a reference bud. Not written in stone. :wink:
