The .243 Win superlite saga (painless method)

[gman82001]

I played hell getting a 90-100 gr to fly in my super light 243 1-8 and settled on a Berger 95.

I have a box of heavy eldm(108 I believe) I’ll be working up once I get it back from thunderbeast for threading so I’m glad you’re making this thread

The 108 eldm will likely be my next try if H4831sc/105 bthp combo doesn’t work out.

Mine sure likes RL22 with the 105's. 2850fps is about all I can get outta it before hitting pressure though. Accuracy is just stupid though

Have heard good things about h1000 and the heavier bullets in a 243. Will most likely see what thats about when I burn up my RL22.

Well, 46 gr of H4831SC did not work either with the hornady 105 HPBT. Onto the 108 eldm.

108 eld-m seated at 2.810” was 20 thou off the lands (barely fits in the M magazine). Loaded one at 47.0 gr of H4831SC. Fired round showed no signs of pressure. Loaded 20 for 100 yard groups. Best 10 round group was 1.4”. Undecided if I will do more testing or stick with this load. Shooting it at distance will probably be the deciding factor.

I loaded mine 50 thou off I believe. I’m also 2 grains under your load since Hodgdon shows 44.7 as max with the 108. Mine shoots about an inch for 10 rounds.

What’s your speed? I noticed that hodgdon data was at 44.7 for standard H4831 but couldn’t find any data on the website pertaining to H4831SC so I just went with the hornady data which is 47.1 max for H4831SC.

2980ish off the top of my head.

I have shot a truck load of 105 hpbt. From a custom barrel that will bughole berger 108s, I had trouble getting 1/2 moa for a measly 5 shots with 105 hpbt. After sorting bullets by oal, they load will shoot 3/4 to 1 moa for 10 shots. That's plenty good enough for hunting or casual shooting for me.

In my experience, hornady bullets are not as consistent as berger. Fpr the price and terminal performance, I prefer hornady. If you sort them, they will do a lot better. If you're only buying a few at a time it is harder. The plastic tip bullets have the same general effect as the Tubb NoseRing that is suppose to help with bc variation. Hornady also does something with the bullet tip on eldm and a-tip to help with bc variability.

Some dispersion is caused by the gun/load, but a lot is caused by the bullet. Variability in the jacket thickness, air voids in the core, and spots in the core where the lead alloy is not mixed well and has variable density will cause dispersion downrange. It took me a lot of shooting to realize this, but a good bullet will make a huge difference in dispersion on target. With that said, a decent bullet will normally shoot well enough to get 1.5" for 30 rounds which is normally deemed good enough for hunting around here.

Hodgdon 4831 data is the same for regular and SC.
