I've been playing with running 42.6gr of H4350 with the 140 Hybrids. So far that is working really well and it's what I shot at the PTS match. I have also played with 42.52 gr (yes, I weighed it to the hundredth), but honestly, it doesn't shoot enough better to warrant the extra work to load that way. FWIW, I had 2 consecutive hits at the mile (1740 actually) this weekend with the hybrids. Might have been the conditions as i tried the VLDs when it wasn't as warm out and they went stupid in transonic.
I have only seen a couple of loads for the 123's. I have about 600 of the 123 Amax, and am picking up my Beanland this week. Anyone care to share loads for the little pills??? Thx.
Hey Demo, thx. What speed are you getting with that recipe?Do we think the 123 AMAX will load up much differently than the 120Amax? I'm having great luck with Varget 38.6 to 39 gr at an OAL of 2.810. It's shooting sub 1/2" moa out of a stock savage LRP. Maybe get started with some Varget around 37gr and work it up?

That data was taken at 50 degrees so I need to see if it changes much for summer time.
For anyone who is wondering, I looked through this thread for guidance on creating a load with H4350 and Berger 130 VLDs. Below is all the loads with that combination in one place.

I just tried 43.8, 44.1 and 44.4 H4350 under 130 VLDs today, three 5 shot groups at 100 each today. 43.8 and 44.4 shot .518 and .513 moa receptively. The 43.8 had the smallest group, but also the biggest (.29 and .73). Odd thing is the 44.1 was just under an inch on all three groups.
I think I'm just at the top of one node with the lower charge and at the bottom of another node with the 44.4 charge

That summarizes as 41.6 to 44.4 with lots of action around 44.0 with a few different primers. Proceed at your own risk obviously, 41.6 is the max in the Berger manual for this load so work up as is customary.
Anyone notice your brass growing .008 to .012 in length between firings?
I anneal every 3rd or 4th firing. Still, when I trim the brass there are hard spots in the necks. I use the bushing dies and I'm using a 288 bushing. I have not seen the neck tension fall off dramatically yet.
From what I am seeing, I'll probably lose the primer pockets first before the necks get too thin. 8-10 firings is about all I expect out of this brass.
skigolf - have you tried any of the Sinclair chamber length gauges to see what the trim-to length should be for your GAP? Sinclair Chamber Length Gage | Sinclair Intl
Thought you might like this as well....Skigolfmike doing some 6.5 Crusading:
I have not looked at a chamber length gauge. I just trim at 1.920
Yeah, but where do ya find R17?
I have 4#s of H4350, then about 10# of IMR 4350, 5# of N160. Has anyone played with IMR 4350 or N160?
I ran out of H4350 and had plenty of H414 laying about so I tried it with some 140gr Nosler CCs! this is the 2nd outing and some good results. it's only at 100yds but I will get it out further next time.
Thanks for posting this. Wish I'd seen it a bit earlier today as I was at the Cabela's in Wheeling, WV and they had no H4350, but plenty of H414. I'll keep this in mind if I still can't find the Varget/H4350 and the 414 is available. Keep us posted as to its longer range capabilities if you can.

let's see...the powder charges were from 41 - 42.9 at .3 increments. Never had a sticky bolt and could have gone higher but it was at an accuracy node I was happy with and fps was as good as I needed so I found it was good for me. I tested the 142's to the lands and it came to 2.850" so jumping is short. I have not varied the lengths since accuracy was good. I have shot it out to 900 yards with 23.75 MOA from a 100 yard zero. I have shot 140 AMAX and 120 AMAX from Hornady commercial loads and I haven't found anything it won't shoot.I have a BlackOps Precision Recon 6.5 Creedmoor as well, but with a 23" barrel.
I'm curious about more details about your accuracy testing like what was your powder charge range tested for RL-17 and details on your ladder testing (distance, shots fired, etc.).
Did you try varying seating length and at what intervals relative to lands?
How much are you jumping your bullets relative to the lands?
Thanks.

Man that looks familiar.....
I thought I remember seeing that the 136L was a hundredth shorter than the 139s?
Has anybody shot the 136 "L" Scenars that recently came out yet?? Got a few hundred on the way and I noticed they're a bit longer than the 139's. Also any ideas on BC?? I've heard .600 or so but no one seems to know for sure. I think I'm gonna go with 42-43 grains of r17. Should have em running 2930 ish. Will post results if I don't get a response...
Aim,
I loaded up a test group of the 139's with RL-17 yesterday. Its going to be good and hot here this week, so I'm going to try and get out Wednesday and shoot them. I saw earlier in this thread that you shot them with good results so I picked up some to try myself. My rifle isn't a GAP, but it was built by Robert Gradous. However, like yours and SkiGolf's, it has shot everything that I've tried in it thus far.
