Powder Test 7mm Rem Mag

[Frank in the Laurels]

..I'll give up a 100-200 fps and switch to H-4350...

Concerning "hijacks" eh... sometimes it's good to pause and bs a little
I thought I posted the latest on the 7mm Rem Mag but I didn't see it here. I switched back to H1000 only I used an unopened jug vs the 15 year old jug (using that to fireform with now).

I haven't shot the load beyond 100 yards yet. I want to see if / where the 180's get unstable. I shot this back on 11/3. I added a tuner brake to it and that got the group size down to .18 @100 yards

Am at 68.8 gr of H1000 at 2912-2917 fps and .442 moa at 100, 200, and 300 yards, ES is 12 fps I believe. 26" barrel 8T. 180 gr vld-h. With 67 thou jump. I'd kept going up to 69 grs. Am not maxed out at 68.8 grs. With no tuner, hunting rifle.

I've got another series loaded to explore the area from 66.4 to 66.7. I want to see if 66.4 repeats the ES. If it does I'll use that and the tuner to bring the groups back in.

The weather and time to shoot hasn't been in my favor. Hopefully I'll get some time soon.

I may go up in charge after I shoot it but looking at the group size minimum values, they just keep increasing as powder charge increases. That could just be a barrel tuning thing but the ES goes south above 67gr too.

(edit: who am I kidding... of course I'll go see what's above 67. That's why I reload)

If you have listened to this, it is worth listening to. I do not like Erik Cortina as a person, not a subscriber of his, but his guest have some good stuff to talk about.

Man that was longgggg. That's what she said anyways. But worth it. She said that too
