Ran some chrono loads yesterday in my 22/250.
RL-26
22" barrel, 1/8 twist
88 gr Hornady ELD
36 gr. = 2838 fps
37 gr. =2890 fps
38 gr. =2941 fps
39 gr =3079 fps
40 gr. =3041
When I see a higher charge weight and reduced velocity that usually means the end of the line. And a very faint ejector mark on the 40 gr load confirmed it.
My old accuracy load in this 22/250 is 32.5 gr RL-15 for 3075 fps, kinda matches others experience, I find that very interesting
Yep, my accuracy loads with the 88gr are right around 3,050fps, as well.
BSA, I just realized I didn't state my accuracy load of 32.5 gr RL-15 was with a 75 Amax... sorry for the confusion, I haven't tried RL-15 with the 88 eldm.
I haven't accuracy tested the 88 eldm load yet but the chrono group was in a verticle string 1/2" wide by 3" tall, so I have high hopes for the 39gr RL-26 load at 3000fps
