Anyone have experience with these bullets using h1000 powder? I'll be loading for a Ruger precision rifle 1:10 twist 39" barrel.
Hornady brass
Federal 215M primers.
What can I expect with these bullets?
Do they like jump/jam?
High speed or low speed?
Do I have enough twist rate to stabilize these? Thank you for your time. - Austin.
 
Hey Austin, I have just started down this road myself. My info so far, albeit minimal, is as follows.
Rifle is a Black Ops Tac built by Mike Bush. Defiance action, 28" Bartlein with 1:9.3 twist. After ladder testing ended up going with the 300gn A-Tip on top of 91.6 gns of H1000. The bullets are proving to be very very consistent and shoot fantastic sub moa groups. Regrettably thats about all the meat and potatoes of the data I have collected so far. Hope this helps.

eta- Primers are standard Winchester magnum
