QL for 243 Win

[EOD Diver]

Howdy Guys,
Hope all is well in your neck of the woods this Christmas season! I was hoping someone might be able to help me out with a QL projection for the following:

243 Win (Nosler cases)
22” barrel length
90 grain AccuBond bullets
RL 26 powder running up to 64K for a max

I know RL 26 will probably be a touch slow, but it’s all I’ve got at the moment. Appreciate the assist!

V/R,

Joe

Joe, RL26 and 90 Accubonds are amazing in my little brothers 243. I worked them up last year and he has been killing all sorts of deer with it. He even mentioned it has put deer down faster than the 120 Partition in his 257 Weatherby I load for him as well. That's saying something right there.

Plenty of room in the case for 26 and the speeds attained are amazing.

Scotty,
I’m really pumped to give it a go! It took a spell to get the components squared away, but I think I’m ready to make it happen. The 90 grain ABs at 3250 should make for a dandy rifle for deer or the kiddos and hearing your results with the combo is music to my ears.
V/R,
Joe

Did you ever get around to trying this combo?

 

[EOD Diver]

I’m afraid not just yet. I went TAD for a spell and am way behind the power curve since returning. I did manage to pick up some 55gr BTs for the 243 though. I’d like to run them as light as I safely can, but I’ve got a little carpentry to do on the rifle first. The LOP is way too much on it as it stands.
V/R,
Joe
