Ballistic twin to 280 so will be keen to see how you go Danny

Nice work ANTSMAN

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

N560 works well in both.

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?

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

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

I'll run that with RE26 in QL.

Make sure the QL info uses the H2O capacity of your fired brass. 7x64 is a ballistic twin for 280.

LOL I switched from N560 to RE26, 2970fps 24" barrel. So similar speeds but find RE26 more stable of the two. N560 59.5gn and RE26 61gn. NB 280AI.
