We'll you need to get it done Alex an let me know how well it faired LOL.
This one is supposed to be for me, so its going to be a while!
Jim, Nosler makes?/sells 280AI brass. I've used their 26 and 28 Noslers brass and found it to be very good. What's your take? Good substitute for Lapua? Yes, I know, it's pricey.
I just like the Lapua brass and the 3006 length and a straight neck, But I'm use to fire forming and turning necks. ..... jim
My experience with Norma or Nosler brass has always been excellent quality, just a bit softer than Lapua. Measuring it out has always been good, but the primers will get loose on you a little quick. For a hunting rifle, especially if your not hammering on it the Nosler will shoot excellent. It measures about .312" across the neck. My reamer is a .316 neck.
Knocked my elk down this year at 325 yards ,went down and did not wiggle with Barnes 145 Lrx using 4831 at 3163 fps. Flat and accurate . 700 action with Pacnor tube MPi stock Swarovski scope. Great all-around cartridge for my use. I have always used Nosler brass with no issues
i shoot 140 gr nosler and it does the job.59.5 /4350,0.10 from lands,3,225 fps.it smokes the deer.lung shoot them or you don;t have any meat on shoulder shot.
I'm running one in F-open. 32 Bartlein barrel, 8.5 twist. Have extensively tried ADI2217 (H1000), ADI2213sc (H4831) and 2209 (H4350). 2217 and 2213sc are able to drive 180gr Bergers at a comfortable 2850fps without pushing the brass too hard - I'm on 10 reloads using Norma brass. H4350 provides the best accuracy in my rifle however, with tight vertical. The 40fps drop is completely negated by the improvement in accuracy. I like the long neck of the case as it gives plenty of seating depth flexibility and it's much better on brass than the 284. I've shot a 284 previously and I'm getting better results with the 280AI.
Stan did you get this built yet? I'll be testing one soon.
Yes it was a hunting rifle with H4350 it shot very well at 100yds 81/2 twist with 180 hybrid.
I ran a pressure test with 168s today. Hit 3100 in 25" with H4350. That case will hold some pressure! That was way too hot, but 3050 was fine. I didnt expect that.
We didn't test velocities what do you think is a realistic velocity for 180 gr in a 26inch barrel.
2900 seems reasonable Stan.
I will inform the guy did it for I told him too keep me posted it shot well right out of the gate I muzzle braked it.
I bought a 280AI Kimber M84 Hunter in April.
Since then I bought:
Hornady dies and bushing
Redding die set
Lee Collet neck die set
Lee FL die set
Lee FL die set
Redding body die
7mm 9" SS Bartlein 27" finish 4# 3oz
7mm 9" SS Bartlein 27" finish 3# 12oz fluted
The only thing I have done yet is
1) Make a dummy round and measure 0.310" neck.
2) Put two Lee FL dies in the lathe and hone out necks from 0.298" to 0.308" and 0.312".
3) The Redding body die is 0.320" neck.
What would the best free bore, a no turn neck diameter? for Nosler Brass, to handle 160-180 class bullets
