So I just loaded some 75s at 2.26“ today to fit in the Tikka mag with a Lever ladder from 23 to 26 gr and does look too deep. I’m thinking I shouldn’t chance these.

Assuming you’re talking about 75gr eld’s? They’ll hit the target most likely but I’d not expect any desirable accuracy… As has been posted the 75’s are too long to seat to tikka mag length.So I just loaded some 75s at 2.26“ today to fit in the Tikka mag with a Lever ladder from 23 to 26 gr and does look too deep.

Yes 75 ELDM. if not a safety issue, would it at least be functional for a pressure test ladder?Assuming you’re talking about 75gr eld’s? They’ll hit the target most likely but I’d not expect any desirable accuracy… As has been posted the 75’s are too long to seat to tikka mag length.
Maybe but you could see pressure show up earlier than it would if they are seated at the proper depth. At mag length you have a lot of bullet in the case using a 75eldYes 75 ELDM. if not a safety issue, would it at least be functional for a pressure test ladder?
75 has a very short bearing surface, which usually means less pressure makes more velocity.Yes 75 ELDM. if not a safety issue, would it at least be functional for a pressure test ladder?
Hornady has a2495 listed under their 223 service rifle loads. 21.8 is max at 2600fps. Not sure why you’re that slow.Disclaimer, I'm not an authority on anything, I'm relaying what I did. If you copy me and end up with a rifle bolt lodged in you zygomatic arch, well you should not have copied a fool.
Rifle is a Tikka with 16.5 inch barrel.
For anyone curious, Accurate 2495 sucks. I could not find load data specific to a 77 gr TMK, but a 77 SMK is 22.6 gr (from what I found on another forum, not a load manual). This powder is supposedly close to H4895, which has a listed max of 22.6 gr with 77 gr Sierra BTHPs. So, I loaded it to 22 gr for 10 rounds. No signs of pressure, load is very lightly compressed with setting 77 TMKs to mag length. Using Fed 205 primers, Starline brass.
This gave me a 1.99 inch group (at 100 yards) with an average velocity of 2382 fps.
For comparison, using the same components, 22 gr of N135 (a full gr below book max), gives me velocities of 2554 fps and sub 1.2 inch groups.
To check, I shot a confirming group with 8 target rounds loaded with 75 gr RMR bullets. My 30 round group with these was 1.66 inches. The confirming group was 1.36 inches.
Too bad, I can easily get AA2495 locally and have trouble finding other single base extruded powders for the 223.
