I'm looking and shooting some 123 Amax's out of my .260 using H4350. I'm currently shooting the 142 SMK's over 43.5gr of H4350. Anyone have a good starting load for these? (Yes I searched diligently).
Thanks for the help.

Did you look at this thread of 8 pages?

Also on Hodgdon's site. They don't list a 123grn bullet but do list 120 and 125grn bullets.

I did actually look through all seven pages. All that was there for the 123 amax was in a 42gr load which is to low and one person said 44.5. So I was hoping for a bit more feedback. 44.5 sounds about right. I will start at 43gr (.5 under my current load) and go up in .5gr increments.
If anyone has anything else to chime in that would be great!
44.5 is money in my 260 with Rem 7-08 brass necked down. Gets me near 2900fps in a 20" barrel.
I am running 45gr in my 28", its a little hot but get 3100fps out of it. I load down to 42.8 and that gets me at 3000fps for the local matches.
I have 2 loads for the 123's
first is a light load of 41gr of h4350 for up to 600 yds, easily 1/2 MOA and negligible recoil.
second is 44.3 gr of H4350 for up to 1000yds but the 142 SMK do much better at that range and beyond.
all loaded in necked up 243 win brass with whatever brand of primers i can find.

I settled on 43.3.
Anyone ever try Superformance with the 123 A-MAX? If not, you should. Meters great also!
I saw a dude I know load some 123gr for his hunting gun and he lives in oregon too. I kinda want lighter bullets than just 140grs
What powder is he using? I feel like Oregon will be in a higher elevation than i'm in and i get very high velocity with 123's out of a 30" barrel. You will more than likely get even better where you are. See my first post for the powder i'm using. High speed,great accuracy,no pressure signs. ...... SEMPER FI!
I run 44.0gr. with my 120's and 123's out of my .260Rem. with H4350 powder.

I am shooting a fine Bartlein Barrel. Thanks for a great product Mr. Green. SEMPER FI!
Shooting the 140 Amax and 142 SMK's now with H-4350, but also want to try the 123's
its like 1-2.5k ft maximum unless you go to eastern oregon then its a lot higher up and I was in the mountains shooting during the weekend and it was like 1690ft
In Louisiana it is 500'. I can only imagine how much faster they would be in you region. Depending on where you are here you could be below sea level in New Orleans. ..... SEMPER FI!
Your welcome! But I'm just one guy in the equation! It's a team effort!
My loads where chronographed and I"m at an elevation of 1100'.

Frank, i have been doing some tests with Superformance Powder and have gotten some very good velocities with vg groups out of one of the 30" 8.5 tw. Bartlein barrels. I first shot the 120 A-Max with a grouping in 1/4" and 3100+ fps. No pressure signs with bullet 12 thou. out. Can't get that good with H-4350 or 4831 in mine. I want to try heavier but right now the bullets are scarce in my location. What i did was reference off of the Creedmore cartridge as there is no load data for the .260 with that powder. You might want to try it one day. Good luck and thanks for the reply. ............ SEMPER FI!
Your welcome Sargesniper!
I'm kinda guessing but is the superformance powder double based? If so I tend to shy away from the double based powders. They are harder on barrels and the barrels will wear out sooner. That's the trade off for getting the extra velocity etc....

Well 44.7 got them to about 2940 in my 22" barrel. Seems like a lot of powder but 0 pressure signs so far.
I ran a ladder through the 44gr range and that 44.7 bugholed them at 100. I'll move it out a bit further and see what they do

Don't really know if it is double base or not. Alli know is that it really shoots good. It is somewhat like H-414. It probably is but as long as it shoots that good with the velocity i'm getting i'm happy. Thanks for your reply. .....SEMPER FI!
In the hornady manual they say to run the 120s,123s, and the 129s the same. But there is no listing for H4350. I run 44.4
Yes they do not want to give anything toward the .260. Maybe they are afraid it will steer people away from the CM cartridge of their's. I wanted to try the Superformance Powder in my .260 with Hdy's 120 gr. A-Max. So all i did was reference off of the CM and really was surprised at the speed and accuracy i got with it. Can't blame Hdy. for not publishing the data though. They are just protecting their own cartridge. The .260 really shines with this powder. I'm waiting to get some heavier bullets and see what this powder and heavy bullets will do. .....SEMPER FI!
Hey Sargesniper, will you post a little of your info on using Superformance with the heavier bullets when you get it? I have a 260 and love it. I shoot 140 Bergers at 2865 FPS using 45.2 grains of H4831sc. Maybe it is silly to try something different when what I do shoots so well but hey, if you can't have fun with it, what's the sense of doing it? Thanks
That's moving right along, what load and velocities were you seeing with 142's out of the Melonited 22" barrel?
I shoot the 142's at 2780 fps. It's a little slow but extremely accurate
123amax
This gives me hope for my 20" melonited barrel. I just started with 140's but have been running 123 amax's at 2875 with 44.6gr of H4350.
That may be quite sometime with the panic still running full steam but if i do happen upon some 129 SST's i'll post. In the mean time i will continue with the 120 gr. A-Max bullets i have. I got over 3100 fps. with no pressure signs at all and the group looked like a 30 cal. hole. 5 shot group @ 100 yds. I feel like i could go higher but why fix what isn't broken? I may also add that this was shot from a Savage 12 F-Class with a 30" Bartlein 8.5 twist barrel installed by Don Geraci here in Louisiana. I feel that 3200-3300 Fps. may be possible but i do not want to push any harder on the barrel. ...... SEMPER FI!
I have gotten good results with H-4831sc and the 139 lapua bullet also. I do not have access to a range close by that is over 100 yds. so i cannot tell you what my loads will do at longer ranges. However i think that they will do well though. I'm guessing at this because my .308 will and did do it some time ago. Being limited to short range is not much of a challenge with loads that shoot this well. ......... SEMPER FI!
Hi Frank, I know this was a really old post, but I ran across it looking for a 123 Scenar / 123 ELD load out of a .260 gasser. Is your load above a bolt or semi? Do you run it suppressed? Do you recall what sort of speeds you got with that 44.0 load? TIA.
I ran that load out of a bolt gun. Out of a 24" barrel if I remember correctly it was giving me right at 2900fps. To confirm that I'd have to pull out my data book but it's at home.
Later, Frank
Thanks. I just ran an OCW test this afternoon with 123 ELD-Ms out of a JP barreled 22" .260 semi build I just put together. Started at 42.4 in .3 increments up to 44.6 of H4350. Top speed was ~3060 and showing promising accuracy. It was a "warm" load, but brass didn't show any swipe and only just beginning to barely flatten some primers. The 123s look like they will work well. I wish I could get my hands on some 123 Scenars to try. But I'm being patient and assuming they will come along.
