    I am thinking of going to 6x45. If I keep going I will end up back at 223.

    Whats the difference between a 6x45 and a .243-250? years ago I saw a guy shooting .243-250 over a chronograph at 3600fps. Fastest thing I'd seen at the time. I never considered using the round until I saw you 6x45 idea. Might give 6mm Creedmore a run for its money.

    6x45 is a .223 wildcat, necked up to .243. You're limited on what bullets you can shoot in the 6x45 due to ogive length and case length, which is why the 6mm AR (6mm Grendel) makes a lot of sense with a shorter case, more case capacity, and the ability to use long target or hunting bullets with high BCs.

    We are doing a 92gr MKZ (Maximum Kill Zone) expanding hunting bullet and a 92gr TMT (Tactical Match Target) in 6mm right now.
    The expanding hunting bullet is coming in at .465 G1 and the TMT at .510 G1.
    I have finished bullets and am in the final accuracy testing phase.

    Buddy of mine gave me some 107gr SMKs for future projects, and I was pleased to see that they come pointed from the factory.

    Little off topic, but I just picked up a Ruger American Predator in 6mm Creedmoor. Was very surprised to see it has a 1:7.7 twist. Should be able to stabilize the 110gr SMK and the 108 ELD-M no problem.

    Off topic a bit also- Article in new shoot times rag--- 6MM creedmore. Top 5 loads mimic My Grr loads to a T. This is what Joesmith and I, & few others were trying to achieve 3 yrs ago.

    Speeeeeeds.

    Beauty is the better diameter of the 6.5 @ same wt. ,,and same speeds.
    yet, mine were from a 16" gun--- the Creed was a 22" rifle.

    It out performs the 6mm Creed , as same as apples. Yes a .257 would be close----- But, we are the 6.5 Grendel gang here...

    I may try to post a pic soon with my new computer. Have some patience.
