G'day

First post here, I just purchased a Steyr Pro Varmint 223 with a 1:9 barrel i was wondering which powder is the most recommend for pushing the 75 Grain Amax. All my experience has been with Win 748.

Regards

KAV

If I may offer a suggestion, I wouldn't try anything over 69grn in a 1:9 twist barrel. I own two 223rem one of which is a Steyr Pro Hunter same as yours. The other is a Savage with a 1:7" which will handle 75, 77 and 80grn projectiles. It has been suggested I could try 90grn proectiles but I believe 90grners need a 1:6.5 Just be careful Kav. As far as powders I'm using BM2 or AR2219 in both rifles.

Sorry KAv, I've mislead you! My Pro Hunter is not a "Varmint".

No dramas. Yeah the Varmint is the heavy fluted version. I have been told that some 1:9 223's will handle the 75gr Amax and others wont. So ill give it a try and see how she goes.

www.ammoguide.com lists 29 loads for 75-grain bullets, two of which are 1052 fps loads. You are probably not interested in those. Join that site; just $18 a year and it's loaded with fabulous info. I'm a member on my second scrip. I recommend it at every opportunity. I can't give you the direct loading info for liability reasons and I suppose what's on there is also copyrighted for member use only. Just join up-- you'll be glad you did...

my Savage 9 twist handles it nicely.
;using many powders but Accurate 4064 accurately pushes the bullet to 2900 fps. 2" group at 300 yds. roger

The best powders I have found for 223 with 1/9

Varget,RL 15 & VT540 no particular order 24gr & up.
But get the Hornadys don't run with 75gr Bergers

In my Savage .223 1:9, I've had good results pushing the 75gr bullets with either Varget or N140. My 1:9 barrel has no problem stabilizing the 75 gr bullets and I know of others shooting 77 and 80gr from a 9" twist.

Varget and the 75gr AMax work well in two of my 1:9 223s, not quite as well in the 16" barrel but still sub-MOA. They really shine in 1:8 barrels and 223AI 1:9 barrels.

you will probably better off with the hornady 75 grain otm rather than the amax. the amax is a bit long to stabilize in a 1:9. it think i shoot aa2520, but can't remember off hand.

Most people have 4895 on the shelf. You might want to give it a try. It's pretty good. Otherwise, Varget, Re15 and Viht 540 are all great powders.

Good luck with your AMAX in a 1/9"!

I used Varget and 75 grain Amaxes for deer last year. Seat them to mag length and crush some powder!
