The .243 Win superlite saga (painless method)

[nuffgun]

Loaded 10 at 45.0 grains of H4831sc and headed for the range. I pulled one shot but 9 fell into a nice little group. Brass looks good.

looks like she'll shoot! I think there is something to getting about 100 rounds down the tube of a new rifle before it starts to perform. Seems like 45 is your load.


lets see some groups at distance!

I have been following this thread closely. I have had a hell of a time dialing in my 1:8 Superlite. I am committed to 103 ELD-X for a variety of reasons, bit have tried most everything from 100-108. I have also tried a ton of different powders. I finally found a load that repeatedly puts 10-round groups under an inch.

44 grains H4831 (42-46 was tried)
103 ELD-X
Federal Match Primers
.7(ish)/100 yards
3000FPS average (no visible signs of pressure)

This project took a while and the gun was pretty frustrating. I was hoping to find a more available powder that would work, but most of everything just ended in garbage groups.

What brass were you using? Bummer it took so long to come up with a viable load.

Remington, Winchester, Hornady, and Starline. Starline is where I landed. Oddly Winchester seemed to be the worst (loose pockets after 2-firings).

Star line was where I started, I got 6 firings out of that batch of brass, I have now moved on to lapua brass to see if I get more firings with the same load of H4831sc and the 108 eldm and possibly less trimming. So far es/sd has remained the same between lapua/starline.

I picked one up, had the barrel cut to 16” by kampfeld. I’m struggling to find a bullet and powder combination that will group where it needs to. Has anyone had similar experience? So far I’ve tried, 108 eldm, 115 dtac, 108 berger elites, and 113 match burners. Dtacs grouping the best thus far. Don’t really want to use them tho. 103 eldx are inbound and so are some 95 tmks.

What is the avg group size at 100 yards?

Really wanted to shoot 108s. 108s grouped a 10 shot at 2.5”. Tried different seating depths annd powders with minimal improvement. Everything else I’ve only done 5 shot groups with. All were in that 1.8”-2.5” for a 5-shot. D-tacs were around an inch for 5 shots so I’m sure they’ll shoot under 1.5” for a 10 shot. Just don’t think they’ll be great for hunting at the slower velocities.

I got one just before October, but didn’t cut it down so it’s got a 20” barrel. I got 108 eldm from copper creek, 90 eldx Hornady factory, and 95 Berger factory. I was trying to not do load dev and just take it hunting, but all 3 factory loads shot bad so I ended up having to anyways.

The 108s shot around 3” for 10 shots, 90 eldx shot 2.5” for 10, and the 95 Bergers shot around 3.5” for ten.

I ended up loading 103 eldx at .030 off jam. Did a 1 gr ladder for pressure with 4831sc and 6.5 staball. Didn’t find pressure but liked the speed with the 6.5 staball so I loaded up 10. They shot 1.6” for 10 and after shooting groups at 3” they looked good enough so I went hunting. I’m planning on tinkering more with them and some 95 tmks here soon.

Was this the 108’s?
