Factory barrel. American gunner 140s
I haven’t shot the DTs for groups lately. But I had to sight in a new scope on an AI with a PVA 18” button barrel. 5 shots
And here’s a 3 shot group from a Proof barreled SP10
And a 3 shot from either the AI or Seekins
I’d do 5x5s but not enough time and I’m not the best shot

Hey wait thats my girlfriend and I don't remember that photo!!!!
Why would you? I took it while she was on me.....dirty slut
Well 223 is a lot of fun. There’s a complete .223 kit with 28” barrel for a good price in the for sale section.
I have a 300NM kit too haven’t had time to use it though. Should be a blast
Barrel just arrived, weight shown is with the monopod in place once I remove it I’ll be
Ready for this years hunts. I have a .300prc being built @20” same fluting but with a lighter contour.View attachment 7391699View attachment 7391700View attachment 7391701View attachment 7391699View attachment 7391700View attachment 7391701

man, looking good On weight. What’s the thought in projectile and estimated velocity in the 20” 300 PRC?
I think that should be doable. I’m over 2900 with 230s. Longer barrel than yours, but I bet you can get there.
Impressive setup. Especially the weight. As you very well know these are not light rifles. I don’t want to weigh mine
. 10#s all dressed up is awesome.My A1 I wearing a Gen2 Razor and a 30” .338 Lapua AI barrel. They feel like very different rifles. LolI think that should be doable. I’m over 2900 with 230s. Longer barrel than yours, but I bet you can get there.

Yup, been shooting mine since 2012. It was initially designed, per DTA, for shooting subsonic 300gr bullets - hence the really fast twist. I did that initially but also found it was good for full power loads too. At 18" it's not the long range beast the cartridge is intended for, it's still really good at hitting hard inside of 1000m and bucking high winds.
250 & 300 grain Scenars run great in it. You'd think 300s would be too heavy for it, but I got surprisingly good performance (92.7gr N570 pushed it to around 2500fps). For some reason I could never get the Hornady 285s to group well at all.
As you can see in the drop chart above, even a 300gr Scenar at 2500fps stays supersonic almost to a mile. For short .338 barrels, I think 18" is the limit to how far you should go. A 22.5" barrel will net you another 150fps, but compared to the above numbers it just won't make a huge difference. That's why 26" - 30" is generally considered the sweet spot to squeeze the most performance out of the cartridge.
Not sure I will have to look. The sp10 is whatever proof makes. The DT I have factory whatever that is then a couple custom. Not sure what the pva is either lol
My rifle and conversions are going to be shipping from SAC any day and I am getting some components together. Question is what bullet are guys liking the best for 223 conversions? I was considering the 75gr berger vld or the 75gr eldm. I have heard of some issues with hornady bullets but i am not sure if the 75gr eldm has been performing well.
Mine likes 77gr Lapua and 77gr Sierra. Both will shoot in the .1s. I have also had good results with 60gr Sierras for varmints. Haven’t tried anything heavier since the 77s have shot so well.
What powder and charge weight did you end up with for the 77's? I will work up my own load but just curious where you landed.
Mine I am shooting Berger 80.5 with 24.5 grains of Varget and getting sub 1/2 inch groups. I tryied World Shooting Precision at 24.4 and getting the same results. Varget is getting hard to find. Speed wise 2880 has been the norm. The Berger 77s are around 2950 with the same powder charge and shoot just as good. Mark knows his stuff with this conversion and as soon as I need a new barrel it will come from him. Have about 2000 rounds through it as of this date.

I had great results with with VVN-140 (25.0 gr) and equally good results with Varget (24.5 gr). The VVN load is well above book max, so be careful.
Limited on time today but shot what ammo I could find in stock for the new 6.5 barrel. American Gunner, Berger FGMM, and the Match 147 all shot 1/2 MOA Or better.
I sent a message to MKMachining about it last year - seemed right up his alley. Didn’t get much of a response.
Yes, I'm shooting 300 PRC. 230 grain A-Tips. 30" 1:9 twist. No magazine issues whatsoever.
I’m shooting a Proof 26” 300 PRC, set up by mark at SAC. 1:8 twist. Shoots amazing. No issues feeding from standard long magazine.
I shoot a Bartlein 28" 9-8.3 Left hand gain twist 300PRC, also done by Mark at SAC. Have not shot it for groups besides a quick zero (it was about 1 MOA with about 15 rounds through tube). I shoot factory 225 ELDM's at about 2940fps according to my magnetospeed. As the other above said, no issues feeding.
Barrel was made by Eric at ES Tactical. K&P blank. I can't recall the profile...magnum perhaps. Will have to look at the build sheet.
How have the Atips been performing for you. I wanted to try them in my Norma Mag but I am a little gun shy from some experiences with eldm's
OK. I'm looking to purchase the same setup you purchased back in January. Now that you have a few months in, would you have done anything differently? Just asking for any advice you would have since your purchase. Thanks in advance.
