Thanks so much..
My wife has a Ruger #1b and I have a Ruger m77 MKII that we are going to play around shooting milk jugs at long range,, I know its not a 6.5 Creed, but they should do Ok.....
Thanks
ED

I see that the loads are for the Interbond not the ELDX.. That's OK should get me going with a load.
Thanks again
Ed

Sorry. Forgot.
I used the inter bond because the 110 ELDX wasn’t in the database.
Forgot to mention that.
