Is it shooting the first two consistently together

not consistently. The first time (couple weeks ago), that's exactly what it was doing. first 2 would be great, 3rd would be 2" left. That was 2 diff powder charges. I was really hopeful that it was just barrel heat and that they were actually good loads.

so to test my 'barrel too hot' theory, yesterday i loaded up those same 2 recipes, and let the barrel cool between individual shots. in one case shots 1 and 4 were touching, but 2 and 3 were on either side for a 2+" horizontal string. Load 2 produced the first 2 shots touching but the third was again 2" or so left.

My 6.5c was a little more finicky with the 123 AH's that i was hoping, but the last 2 range trips have been solidly 1/2"-3/4" which makes me happy.

I have some 162 AH's I could try in the weatherby; but I'm going to try 4955 with the 178's before i switch bullets.

Very nice. Now run that same load out to 300 yards and see what you get. I had a very nice group at 100 and 200 yards, but it opened up significantly at 300 in my 7 STW. I shot the 177 Hunter that same day to make sure I wasn't the weak link, and it shot great groups. So, I'm sticking with the 177 Hunter. I had the same issue with the 140 Absolute compared to the 143 Hunter in my 280AI.

That's really interesting, and good to know. wonder why that happens? i'm too much of a newb to have an idea.

I don't know the answer and sent an email to Steve about it. My guess is since the bearing surface area of the Absolute line is different than the Hunters. Sometimes your gun just doesn't love the bullet you want to feed it. I also think the twist rate and the higher velocity may play a role here. I have a 1:9 twist in my 280AI and minimal twist for the 140 AH is 1:9.25. It may just not stabilize the bullet enough in this case. We are finding that it's better to have a much faster twist rate for the Absolutes than to be closer to minimum twist rate.
 
Here are some results of a 25-284 1-8 twist 25in Barrell I've been working a load up for , Hammer 90 gr absolutes cci200 lr primer Lapua 6.5 -284 brass necked down with 6.5 284 Redding bushing dies using a . 283 bushing oal 2.880 with H4350 57gr 3595 fps 57.5 grs 3626 fps 58 grs 3667 fps 58.5 grs3693 fps 59 grs 3774 fps very faint ejecter mark 59.5 grs 3816 fps ejecter mark leaky primer . 004 neck tension no crimp . I had easy bolt lift through out pressure test but feel this as far as should go with H4350 . This is new brass so after it is formed too chamber i might could get a little more out of it but I'm going to work on a load between 57 grs and 58.5 any advice welcomed hope this all the info that's needed too post thanks. Note the 6.5-284 bushing dies with a . 283 bushing necks down too 25-284 with no problem at all .

Sounds good thanks for the response I'll post some accuracy results when I get it tuned up . I was doing load development in 92 degrees Tx heat I'm going too let things cool down a bit for farther testing this summer has been brutal . I've been loading a long time but learn something new nearly every time I log in on LRH thanks again for all the free advice and imput you-all contribute
