7 SAUM load data

[Pudgy]

I have the exact Rem mod 7 22" and have a great, nothing fancy load of Sierra 160 HPBT GameKing with Hybrid 100v loaded mag length @ 2900.
I also have a load of 168 ABLR with R-23 loaded SA mag length of 2.840" COAL.

What's your data for the 168 ablr? Like to work one up.
Also here's some data for 22" 1:8 TW ADG SAAMI/ coal 2.9640 - N560 - 184-f. Should Be close for the 180 hybrid. Hybrid will likely see 25-35 fps faster.

I have powered on several powders including n560, n565, rl23, rl26

I was not knocking n560 above. I was informing that it is not temp stable. It's not bad and is a gray powder in the saum when used correctly.

My favorite powder out of a proof barrel is n565 with 180's. It's stable and burns a lot like h1000 with just a tick more velocity

Appreciate your input @Longtine88 I think you've done your homework!

Whats your preference of berger 175 elite hunters vs 180 hybrids? Since we're on the topic

Here's my SA mag length load data for 168 ABLR.
Slightly compressed.
I don't have the velocity handy but I'm sure it was just around 2900 in 24" and mid 2900's in 26".

I actually like the 175's better. But not much. I have had great luck with the 180's. To me the 175's are super easy to load. I use both for elk, deer, etc. I have never had an issue with either.

Here is some data on H1000 & N565 the 184 F. Both had equal velocities- es-Sd. But N565 had a wider node at slightly higher speeds.

Hey all, just curious if anyone has any data for the 143 Hammer Hunters? I'm running a Tikka action, 1-8.25 twist 18" Carbon Six and ADG brass. I started with RL-19 and had a good node between 62.2 - 62.6 gr. and 3046 fps. That was at 54 deg. F. This morning I went back out at 30 deg. F and 62.4 gr averaged 2980 fps. I'm guessing that RL-19 isn't very temp stable?? I am using Fed 215's and after reading through these posts I'll be switching to BR-2s or Fed 210s.

I've got a pretty good load with 168 Bergers using 59 gr of RL-23 @ 2800 fps

Dang! Thank you!

a lot of the reloader powders are double base powders which makes them less temp stable. Some of the newer to powders such as 23 and 26 are supposed to be more temp stable.

RL26 is no where near stable. RL 23 yes it is stable.

I just went through load development this week on my 7 saum with the 143 Hammer Hunter! Here's what I came up with.

22" 1:8 tw Benchmark Carbon Sendero Light

143 Hammer Hunter @ 2.985" COAL (.050" off)
N560
ADG
Fed 210M

Found pressure at 65 Gr (heavy bolt lift). I ran a charge weight ladder for pressure from 60-65 in .5 gr increments. Then backed off and shot groups from 61.5-64 gr in .5 gr increments. 62 & 64 gr are the lower & upper accuracy nodes found. Both consist .5" or less 3 shot groups at 100 yards.

62 - 3030 fps
64 - 3100 fps

Hope that helps! I imagine RL23 would do well. And also, switching to the Fed 210M's showed significantly lower ES/SD compared to CCI250's from my testing. Thanks @Longtine88 for the tip on that one!

Usual caveat, this load is for information purposes only. It is for my rifle only.

I have a 22" 1:8 TW both loads were below max and chosen for nice nodes and .25-.3 10 shot groups with single digit SD ES under 20.

ADG - Fed 210 - COAL 2.975

H4350 56.78 - 3014 fps
H4831SC 60.2 3023 fps
