 Best weight bullet for 1-8 twist 18" 223

Ok guys I have about 400 cases ready to be loaded and I'm loading them for a 18" POF .

I've been shooting just some cheap 55gr bullets threw it with ok 100yrd results but now I'm ready to shoot some paper the right way.

It has a 1-8 twist and I think the twist is too fast for 55gr and a gun builder I know told me the same.

What would be around the best weight and bullet for the best accuracy to use when loading these up? Also I'll be hunting with them so needs to be a good accurate bullet for hunting varmints as well.

The gun builder you know is wrong. You're good from 45-77gr with that barrel. Accuracy? You'll have to find out what it likes.

This. My Douglas 1:7 barrel shoots Factory Hornady 55gr V-Max almost as accurately as my hand-loaded 77gr SMKs.

+1
This might give you some insight into your question, Take this back to that gun builder so he will stop spreading that myth.

As for "best" bullet, it depends.

On my rifle, 18" 1:8 twist, I have gotten great results from the 77gr Sierra HPBT over 22.5gr of Varget. I have also shot factory Speer 64gr GDSP from the same rifle and the results were mediocre. YMMV.

My 1:8 rifle likes heavier bullets. Particularly the Sierra 69/77g Matchkings. I've found Varget is a great powder for bullets over 55g.

my 20" 1:8 twist wilson likes Sierra 65g SBT. I can shoot smiley faces at 100 yards prone.

You know you can't load those to mag length, right? They're too long. You want the 75gr BTHP.

Please put any posts about powders or reloading in the Reloading Forum (Armory board).

Yeh I know now. I thought I could just seat them farther down but way too long. Shot ten but don't group well naturally so 90 bullets to collect dust.

mine likes the 75 and 77s the best. but it also does just fine with 55s.
55 gr ,, well you cant shoot cheap stuff and expect much. I only shoot better stuff like hornaday though.
if you are making your own use some of the better quality stuff, the projectile cost isnt very much of a difference between the cheap and the better.

OR simply load them as required and single feed them. no need to waste them by non use.....

Cant tell you how many times I have had to do this after trying new bullets.

IMO Sierra 65g SBT and 69g matchking BTHP are the best. Only reason I should the 65g SBT over the 69g is because it is good for hunting and shoots just as accurate.

P.S: Dont buy 70g Speer SP either, you have to seat them too far down because they are so blunt. Also anything with a ballistic tip over 70g wont fit.

First post and all.

About the only thing that a 1/8 won't shoot well is 62 grain tracers.

Time to buy a bolt rifle, then.

my 1:8 twists shoot just about everything but seem to be the most accurate with 69 gr sierras

55gr Vmax (Only thing I would buy hornady for, if your trying for precision)
69gr SMK's
77gr SMKs
77gr Nosler BTHP

I love justifying the purchase of another guy because I have either extra parts, brass without a home or bullets I need to shoot.

I have a Douglas 20" 1:8


For the OP, I have tried from 55gr to 75gr and my barrel was fine with everything...

I have a 20" 1:8 bull barrel and I have been trying out various loads. I have found my gun hates 55gr loads and loves either 50gr or 69gr+ loads.

You can see my 10 shot group collection here:

Shot at 100 yards with a bipod and home made rear bag, PA 4-16x scope on 16x from a bench. Running through varius loads to see what my rifle likes. Upper is a RRA Predator Pursuit 20" bead blasted bull barrel, lower I assembled with an OK trigger job.

My BHW 18" 1/8 shoots Hornaday steel match at .9 MOA. It's favorite load is 77 Nosler over 20.5 of H322. .75MOA with that load. The 1/8 is very versatile. Find a projectile that suits your needs and that your rifle likes. Mine doesn't like Hornaday 75grn match. You just never know until you try.
