200 grain Wildcat 7STW load data

[Freebore]

Would like to see how well these bullets perform but I only have a limited number of available. Looking for data using any of the following US869, Retumbo, H-1000, 8700, RL-25, IMR7828.

I've been shooting 180 bergers in in front of 77.5gr of Retumbo and I am getting 3280fps out of my 30"long, 1 in 9 twist. What length and twist of barrel are you going to try the 200's in.

6mm shooter
I have a Weatherby Accumark 26" 1/9 twist. Looking to see if someone has tried these 200's in an 7STW. I only have 15 to see how they shoot.

I have an STW 1/9 twist, haven't shot the wildcats in it, but have shot them in my 1/9 twist 7mm Allen Mag, they stabilize pretty well, shoot as good as anything else.

i've shot the 200's out of a 7rum but i used 872 powder and 215 primers. 90 gr was where the bolt started getting a little sticky.you might use 9 of the bullets and shoot a ladder. then shoot 2-3 shot groups?

Re: 200 grain Wildcat 7STW load data .... Keyholed!

Dave,
Went to the range today tried Retumbo 2750fps 3 shots keyholed. Tried AA-8700 2825fps 3 shots keyholed. Tried US869 3025fps 3 shots....keyholed all at 100 yards.
Think I'll stick with the 160/175's /ubbthreads/images/graemlins/crazy.gif

Freebore,

I'm sorry to hear about your luck. I'm puzzled /ubbthreads/images/graemlins/confused.gif.


WAMBO, have you had a chance to shoot yours yet?
