After 1100 rds on the 243 win it was time to do some load dev and make an adjustment to my charge.
I shot the top row straight 3 shot groups at 100.
Bottom row was shot round robin 1 shot from each charge weight at a time.
I'm think 42.3grs is where I need to be at as 42.1 and 42.5 also perform well, but with a flyer in each groups.
What do you guys think?

wheres the pic?
Good call!Originally Posted by LongRange
42.3 is it...try adjusting seating .005 both ways and shoot it again or just shoot 3-5 rounds at 300yds and see how it looks...it may be on its last leg too.
Those two groups with the 42.3 measured just about .400 center to center, so not to shabby for a last leg lol.
Remember these are 6mm holes!
yep and at 1100 your coming up on the last leg quick...i want to build a 6mm but the barrel would be shot out before i was done tweaking the load LOL!!
you too a?........Ive been eyeing 6mm as well but a 6mmbr instead. brass aint cheap though.............

If you're going that route go 6 Dasher and still reach 3000fps with a 105. Otherwise just shoot a 6.5.
that's what im currently shooting................but wouldnt ya know it........DanSavage posted excellent results with his 6mmbr and expensive 105 barts bullets!
my model 10 FCP with HS stock and 5R 11.25 is tired. It just gives me an excuse to add to my addiction.....................ya dun did it again Dan!

I get it and 6br is unquestionably accurate, but I just don't see the point of shooting a slow 6 haha.
Ya good thing I have a matching barrel on the shelf ready to go!
Are you going to shoot the barrel on it now until it's done? Curious to know the round count when it goes south.
Lookin' good, Sarge.
What weight bullet is that & what powder you using?
'Scuse me while I whip this out...!
105 amax.
Ya, I won't pull it unless I decided to go shoot a big match. Can't have a barrel go south in the middle of the big show! Last one I pulled at 1400. I'm going to push this one a bit.
Let me know...if I do a 6mm I'm pretty set on a 243AI...if you can get 1500 through that barrel I think an AI might get 900-1000 before needing to be set back.
well played wolf..........after 1k worth of pills tossed out the barrel?...things are bound to change.
42.3 it is.
you gonna play with seating depths as well?

Maybe a little. I actually have to re-measure distance to the lands. I don't know how much closer I can get to be honest.... That is why everyone move to the 6 Creedmoor, 6XC, or 6x47L.
understood.

One more note, this brass is on its 4th firing. I still don't have an annealing setup, so I would imagine that it would make a difference as well!
Good point. What are the average speeds from a 6mm br with 105,s
I believe the 2800 Area. 3000-3150 is what makes them advantageous over the 6.5's.
I can live with that speed..............whats the life span of the 6mmbr barrel?....2k rds?

Yeah, I've toyed and toyed with the idea of a 6mm, but just can't stomach the barrel life yet. I've looked hard at the 6 SLR.
If you're already running 6.5 Creedmoor just go 6 Creedmoor. No sense in beating yourself up with all that extra work.
