2nd Round W/ .257 Bee

[Powerstroke]

Made it back out for the second time with the Rem 700 in .257 Weatherby.
POP has sugested as well as seeing others on here to try the IMR 7828 w/this round. :grin: It was well worth the purchase. I haven't touched anything since last week other than a good cleaning..... trigger still has not been touched.... :grin: first 4 out of the barrel today. I tried more of the N-165 & N-560. I think I'll stick with the IMR 7828.....???

 

[FOTIS]

Yup!!!!!!!!! :wink:

Powerstroke,

Nice shooting, looks like IMR7828 is the powder of choice for the 257 Weatherby. With a 3398 MV and a 300 yd zero, she is a flat liner.

JD,

Which one of the web-sites did you pull that from ?

I'll have to load up again and go out and make some minor adjustments. I was going to take the .260 on the next yote trip, but not now..... :grin:

Great shooting an groups. If I could do that with my 06
I'd be happy.

Powersroke,

Here is the link-
http://www.biggameinfo.com/

Register, its free although I don't think you actually have to to use the calculator.
go to Ballistic Calculator, and then Advanced Calculator

Lots of variables you can input, the results are sometimes very interesting!
I used your muzzle velocity of 3393 and a BC of .418

Very flat shooter. Only the 7mm RUM shoots flatter but with a greatly reduced barrel life.

If you want, give me a call and I'll walk ya through the Ballistic Calculator.

Great shooting there...looks like a darned good load!

 

[Powerstroke]

Thanks Guys !

I actually use BigGame info all the time... just never have made it that far I guess.

Powerstroke, great shooting. You can work that charge up to 71 grains,that gave me 3525 average velocity and the groups actually shrunk as the velocity went up. I then played with primers and found my best accuracy with rem 9 1/2m's. :grin:

 

[FOTIS]

Primers are truly an enigma! A simple primer change can half or double a group.

 

[Powerstroke]

I actually did shoot a group @ 71.0 grians and it was just slightly over one inch.
Very close on the same velocity however... I averaged 3522 for the group.......

For bone stock out of the box I don't expect any better from that group. I did purchase a box of 100gr B-tips to play with too, so we'll see where that one goes....
