.280 rem with a 22" barrel?

[vegas steve]

i checked shooters pro shop and they dont have any at this time.im looking for some once fired brass to handload if anyone has any they dont need.i have quite a bit of 30-06 brass if anyone wants to trade,i also have a bit of 6mm rem brass too

Tonight im cutting,crowning,and threading my 280 barrel,and will be testing loads and fireforming brass this sat.i will post pics and results

 

[vegas steve]

Barrel break in went well,but trying to test different loads while fireforming brass was a joke.i did manage a couple decent groups with slow powder,and the short barrel did clear the 2900 mark.now that i have some good brass i need to do it all over again.

one thing is for sure,fireforming 280 brass from false shouldered 30-06 brass sucks.it works but it seems like it's hard on the gun.

went out again today and chrono'ed a few rds with the formed brass. 58.5 grns of imr 7828 went 2930 out of the new 22"280 barrel with the 162 eld match by hornady,and grouped less than half moa.further tweeking of this load could easily net sub 1/4 moa groups.i'm stoked.this project was a total success.

Is that 7mm rem mag velocities out of a 22 inch barrel??

 

[vegas steve]

Naa my 7 mag will do 3100 with a 180 smk,but i am impressed with this stubby .280 barrel

 

[vegas steve]

load testing again tomarrow morning brfore the rain hits.i will post my results

 

[vegas steve]

well i tested 3 powders, 2 seating depths,and one bullet,and the best overall combination was 58.0 grns of rl22 with a 162 eld match averaged 2910 fps with zero pressure signs and 1/4 moa accuracy at 100 yrds.i also tried imr 7828,which grouped well,but gave pressure issues once the 2900 mark was met. h4831sc was a big dissapointment,netting slow speeds and non impressive groups.so now i have a great carry rifle,that weighs 12.5 lbs,shoots well and does it with a 22" barrel.

Nice rifle. I would have never of thought of a .280 as a "tactical" rifle. Overall good looking setup.
