243 Winchester 1:10 twist long range load

Those should do really good

Sooooo with the shortages, as previously indicated, I scored Nosler Accubonds 90 grains, 200 of them. I will be working with these bullets, and either RL-16 or RL-17

I'd use the RL-17, start at ~38.0gn and move up, max ~41.0gn. 3150FPS+/- depending on brass. Case fill per Nosler is in the 80% range, not uncommon for the 243 WIN but would make me use the slower 17 vs faster 16 to start.

Charge weight for RL-16 would be ~1.0gn less than with RL-17, starting and projected max.

400 yard is pretty easy with what you have. I've done two with a 10 twist for a few friends and they perform well on large deer at 400 here in Michigan.
So my first load that worked very well was the 95gr nosler bt. One really liked them. The other didn't and liked the 90gr.
That being said they both liked the 70gr hammer hunter and we were able to get enough speed where it outperformed both the nosler to 400-500 yards. That being said if you are a experienced Reloader and you will not get a better 500 and under bullet than the 69gr absolute hammer. The speed you gain will roughly 3800-3900fps will offset the higher bc.
In fact you could do a max point blank of around 400 yards with that round if you got it to 3800fps. Point and shoot is always good.

I have started working up a load with the 69 absolute with very little success so far. What powder do you recommend?

Thanks in advance. Fed-Well

I was using staball 6.5 in both with the hammers.

Congrats on getting some 90 accubonds,my hwy 243 ,1/10 twist dotes on them with H4350 one grain from max . I'm a big fan of Alliants but I hear RL/17 is tuf on barrels ,100 Sierra bts shot fantastic with a max load of H100V =3200 fps. Bac to them 90's I'd say try RL /16 first but that's your call . Cheers

Tough on barrels?? No worries, I see them like brake pads or tires LOL Its a wear item.

 

[Double Dropper]

According to a recent barrel manufacturer, most barrels only last 6 minutes.

hoping to extend this to a 400 yard killer.

You could get there with RL-26 and conventional 100 grainers like GK's, Partitions, Interlocks, etc..

 

[Double Dropper]

No RL-26, I have RL-15, 16, 17, 22, 25,

 

[59FLH]

IMO the 16, 17, 22 and 25 should all be able to get you into the 3,000-3,100 VL range assuming your barrel is 22" or longer.
That should be 1000'ish ftlb at 400yds with 100 grainers.
It wont kill all of it, but it will kill a lot of it.

Looks like I need to find me some H100V! That 100gr. SGK at 3200 must be impressive on game.

No RL-26, I have RL-15, 16, 17, 22, 25,

Since you have all these I would revise my advice to say load the RL-22 first, and see if you get any pressure signs before you run out of case room. I mainly use IMR 4831, and RL-17 and RL-22 roughly straddle that in burn rate.

 

[Double Dropper]

Rl-22 over RL-17? with 90 grain bullets?
