70 grain 223 load for 1/9 twist?

[PSL1078]

I want to load soft point ammo for my 223 AR. I have been looking at some 70 grain bullets. Would this be too heavy for a 16" SS barrel with a 1/9 twist? If so, what would the max weight SP bullet for this gun be? Anyone have personal experiences?

My best advice is to go shoot it and see. My 1 in 9" twist savage will stabilize the Hornady 75gr bthp, but a buddies AR with the same twist won't throw them into anything resembling a group.

I had a 16.5 with 1-9 twist and things started to spread anyhing past 69 gr. Groups were running 1 3/4 to 2 inch at 100 yards. When i went down to 55s groups went to 3/4 to close to 1/2 inch at a hundered. Have a good one

I have a couple of 1:9 Ar's and a Savage Police M110 all in .223 they all perform quite well with the Sierra 77 being pushed by 24.5 grains of Varget

I've shot the 70gr Speer semi-spitzer in my 16" 1/9 AR. Very accurate.

Being a flat base, and semi-spitzer, it's not terribly long for it's weight. I was loading 25gr W748 for about 2750 fps.

My savage PC .223 with a 1-9 will shoot 77smk very well, it is actually the best load in this rifle. It will not shoot barnes tsx 70gr bullets at all, they key hole they are too long.

I shot a white tail in the head from a distance of 80 yards. The 70gr Speers worked fine. Not sure I'd trust it for broadside shots though. Don't remember my exact load but, I do know it was Reloader 15.
