I've started to run low on Re26 and have gotten frustrated with erratic behaviour from it at times anyway, so just switched to AR2225...

Both the last groups come in at 0.290" and 59.2gr was a mild 2980 with good ES/SD.
Interesting what was your 26 speed and charge? I was under the impression it’d be no good because iv being told no good in saum good to see some real world
Right around the Hornady "max" for similar speed.
@Pommy they are some great groups there.
I'm using <70gr of 2217 in a 300WSM with 225gr ELD's and Fed 215's. <45gr in a 22-250AI and 88gr ELD's with Fed210's. <60gr in a 284WIN with 180gr ELD's and Fed210's (holy shit it's becoming clear how much of a Hornady fanboy I am). All three of these are virtually full cases and Re26 gives more velocity in all three instances... but that's kinda to be expected what with it being double based. My understanding is Re26's burn rate is right around that of AR2217 but it's a fair bit more energy dense.Quote:

That's interesting. I love ADI powders (Hodgdon)...what is supply of 2225 like at the moment? A 24" barrel like mine can make use of a slower powder.
Probably only a fraction better than rl26 supply, you'll be lucky to find it in retail stores until next shipmentQuote:

Even with a short barrel, it can still give more speed. It's matching case capacity to bore ratio and bullet weight, more than barrel length has anything to do with it.
Really enjoying this thread….

Interesting the mag length is 3.060" and the COL touching lands hard with 143gn ELDX is 3.035". I have some loads prepared at 2.955" and some 150gn LRABS at 2.925" so a massive jump.
Will load some at 3.015" COL for 20 thou jump? Are ELDXs very jump sensitive?
Not in my experience :thumbsup:Quote:

Because you effectively have a bigger case if it's not half full of projectile.Quote:

143gn ELDX on left at 2.955" COL and same again on right at 3.015" COL (30 thou jump and fits in mag). Testing longer length at 60 and 60.5gn with RE26.

Holy hell where did you get all the 143 fromQuote:

I tend to go OTT when getting into something new. No 7mm in the cabinet now except a young fella I load for every now and then...but always could be drawn back to a 7mmSaum in the future after having 2 of them.
150gn LRabs not very good. Abandoned.
Longer COL shot worse and same pressure signs with 143gn eldx 60.0gn so 60.5 abandoned.
59gn with 143 eldx seems best but groups not as good at 2.955" - probably me.

I shoot the 142 ABLR in my Creedmoor and .260 and they shot real well with alot of jump.
Sent from my CPH2145 using Tapatalk
These had about 110thou jump. Can have the handful I have left from sample pack...12 I think.
Thanks for the offer but i have plenty, better to offer them to someone that wants/ needs to try them out.

Here if anyone wants them.
I'd like to give them a go in the Saum, have had a look at them but never got any.Quote:

ELDX?
Yes.
Time to go shoot some deer with it.
Yep load development finished.
Does your Labradar function set that far back from the muzzle? I normally have to have muzzle end in line roughly with both rifle and pistol, I use an external mike with suppressor.Quote:

Attachment 205755Attachment 205756 tried out the new magnetospeed this morning and happy to now get a result for every shot unlike the optical one I had. Groups are pretty good considering it hangs on the end of the barrel. Now going to stick with 60gr and play with seating depth a little to try get the ES down.
I could be wrong but I have always used charge weight to get ES down then fiddled seating depth to improve accuracy....with that in mind I would be looking at somewhere between 59.6-60 going off your results and tune accuracy with a seating depth ladder....just my 2 centsQuote:

Are you guys head shooting ants?? :)
I think of it like a 1600CC engine and a 6000cc engine both being fed say 10 mls of petrol per second.... the 1600 will be reving its nuts off and the big 6ltr will be at idle.Quote:

or so I believe.
Oh well in that case I'll leave it alone and go head shoot some ants ��Quote:
