I am surprised by the speed. Wow, these things were moving. I cut open a few cases with a dremel and no case head separation signs at all. I checked chronograph with a known load and it read fine. I'd like to know what others are getting. I was expecting 100fps slower.

I would say about right. 200AB with 72.5 gr RL22 gives me 2960 in 26" barrel and is a little faster. RL26 gives me over 3000 at 74 gr so think you are in ball park. I have too much 22 and 26 to change right now but RL23 does look promising for sure.

Love the 200AB in the 300WM and seems to shoot pretty good out to 500 for me. Farthest I have been able to stretch it out so far. RL22 is not temp friendly so thinking RL23 should be better.

The stability of RL 23 is a real plus though. Good stuff!

The 71gr seemed to have a bit less felt recoil. Not so sharp. Might focus on 70-71gr. Keep it around 2900.

Dang! I'm shooting 190 ABLR's with 72.5, RP brass and CCI 250's. It's proving to be a very accurate load. I haven't chronographed it yet, but I was expecting to see 2850 at best. This is good to know. Thanks for sharing!

Oh boy. You should be pushing 3000fps! You're welcome.

I run 4 300WM rifles (I know I'm blessed), with either 200gr AB's or 210gr ABLR's.
All have 26" tubes and velocities with H1000, RE25 or RETUMBO run right through 2950-3050fps.
Most run 77-78gr of H1000 with either 200gr AB's or 210gr ABLR's, but one really shines with 81gr of RETUMBO and the 210gr ABLR with 3048fps. The 210gr ABLR is about 50-60fps faster than the 200gr AB in my rifles.

I also experienced the tightest groups with a 180gr AB in my Kimber 8400 Select, this is used for stalking, so long shots are really not necessary in this rifle and the 180gr does a fine job on elk size game.

Cheers.

Retumbo under the 210 Accubond LRs? And how do they group? I am finding the tightest group in my custom rifle is with 180 grain Accubonds as well.

That rifle is a Rem 700 LR, it shoots those 210gr ABLR into 1/2 MoA @ 600mtrs and 3/8 MoA @ 1000mtr.
It shoots almost as good as my comp guns.

Farthest shot to date with that rifle on deer is 1300mtr, bullet performed perfectly and still exited. Really loving these 210gr ABLR bullets. Stella performance on all hits, close and far.

Cheers.

P. S.
Haven't had a chance to try RE23 yet, it's never in stock here. I also heard it is faster burn rate than RE22. I prefer slower powders generally.

The interesting point to remember is both the 190ABLR and 200AB have high BC's so that extra 50 or even 100 fps is somewhat meaningless for 90% of the distances you would shoot game at anyway relative to drop and energy. I find what I like about the higher BC bullets is to do exactly which can be more accurate, less impact on brass life and obviously less recoil which also helps staying on target. In fact, I just loaded some 300WSM in 200 ELD-X where I am bracketing the velocity node of 2875 on either side by 0.3 gr powder to find the accuracy node. I can push the 200ELD-X close to 2975 from 26" barrel but I wasn't overly impressed with the accuracy and saw very faint ejector marks. You had to really look hard but they were there. Less than MOA but I believe it can be better option to go down the ladder for a better node to try.

This is a very good point. Especially for those of us who are loading RL23 under high BC bullets. I say this because RL23 appears to have a lower density than many of the other powders I've worked with. All of my ABLR's that are a COAL less than 3.285" are definitely a compressed load by volume, at 72.5gr in a .300wm that is trimmed to 0.010" less than max.
