22-250 and 88 ELD-M and Non-Alliant Powders?

[BigSky!]

I have searched this and can't seem to find any load data for the combination of 88 ELD-Ms in a 22-250 other than RL-17, RL-16 and another RL that I don't recall. If one didn't know better, one would assume Alliant closed their doors. So, I thought I would start a thread with load recommendations for non-Alliant powders in a) 22-250 and, with, b) 88 ELD-Ms. Heck, even Hornady's newest update of their app doesn't even provide load data for the 88 in a 22-250.

I am shooting 88's in a 22-250, I did not find any data. Just took good guess.

I am using 7828, just because had lots of extra. Will move too H1000 afterwards.

I'm shooting a 22 Creedmoor(slightly more capacity than 22-250) with H4831sc and 88s. Also have a load with n565 which is reportedly almost identical to RL 26.
H4350 and 7828scc and h1000 are all good to try also.

Hey, I'm working on a 22-250AI. Here is a Varget load with the 88gr ELD-M
32grs
Rem 9.5
Rem case
.275 group at 100yds
This was with a hydro-formed case and was the first fire on the case. I still have more load development to do but it was a great group.

@2.600" n550, hunter, 7828ssc and imr4831 are top contenders and few being over 100%. The case taper is why the creed has the edge with capacity. I checked several sites and used 90gr for referencing. If you have a Berger book then check their as they list a 90gr for 22-250. Not sure what the bearing length of either bullets are, but the 90gr Berger's are long.

What twist is your barrel?

The case taper is why the creed has the edge with capacity.

The case taper is one complaint I have with the 22-250. It does stretch pretty fast with FL resize or even partial FL resize. I favor partial FL resize. Neck sizing only gave me some resistance while chambering a round, I didn't care for that. So IMHO that might be an area where the 22 Creedmoor or 22-250 AI has an advantage.

What twist rate is your barrel?

Thanks all for the input. There are clearly some I assumed would work and others I hadn't thought of using. I appreciate the input. To someone who asked about my barrel twist, mine has an 8 twist. Yes, I know that one is supposed to use a 7; but, many have used an 8 and stabilized them. I don't want this thread to turn in to that debate if I can help it because unlike Hornady's super secret load data for their own bullet, that matter has been hammered to death.

Thanks BigSky! I have a Ruger Gray Target that's 1:14 60 gr is it's max

 

[waspocrew]

The Sierra App has load for 22/250 with the 90 gr SMK. This should give you plenty to work with.

Hey, knew I'd forget something the twist is 1/7 and it's a 25 in carbon 6 barrel.
