Thread: 280rem +162 + RE26

As close as I could get with RE26 to 60kpsi with @southernman data.

thanks mate ! ^^

so finally chronod some loads .

so finally got to range to chrono me loads.

280rem Browning A Bolt- 162eldx over RL26.

3 shots averaged.

56.5g-2750fps 75fps between highest and lowest. 1 x lightly sticky extract- no extractor marks

57g -2795 fps 122fps between highest and lowest.1 x lightly sticky extract- no extractor marks

57.5g -2780 fps 23fps between highest to lowest- no extractor marks

58g - 2819 fps 36 fps between highest to lowest.1 x lightly sticky extract- light extractor stamp

58.5g - 2844 fps 69fps between highest to lowest- extractor stamp

59g - 2921fps 7fps between highest to lowest- decent extractor stamp

I am unsure if my old chrony is telling me porkies- so need to check with another newer chrony- and buy some new brass- as this stuff is 3 to 5 firings along.
2840 seems alright for 162s in 280 rem?
It sure is a please to shoot suppressed.

Those are some massive velocity spreads, heres hoping the chrony is misbehaving a bit or new brass helps. I'd have thought you would get a bit quicker before getting pressure signs like you are, seems like either funny reading or something else might be amiss

exactly what i thought mate- i was very methodical and finicky with powder measuring too, weigh- remove re weigh- remove re weigh ...

That looks bloody close to the QL prediction...and is 2gn and 50fps less than my AI.

yah- i have to get new brass to start fresh- and borrow mates chrony to be sure. I was at the range tryn to remember the speeds you had posted for 162s in AI- .

my bottom two pics the extractor marks are excessive aye? and the middle would be ok?

Just the bottom one on my phone looks too hot. Play with seating depth. Then may be try a primer swap from LR to LRM or vice versa?

Ejector stamp is visible but what you don't see is your primer pockets enlarging as well, these usually go hand in hand.

anyone tried ar2225 in 280 or ai? Need to load for 7mmrm soon, and RL26 is blardy scarce still................

N560 works a treat in my 280ai

thanks mate- yeah sorta wanna kill 2 birds with 1 powder
if i can

edit- oh i see n560 will do 7mmrm also....

You don't need a 7mmRM if you have a 280AI

N560 works well in both.

I know I know- the 7mmrm is not mine- im happy with 280- killed 4 deer out to 450 , just not happy with lack of rl26
