Not a surprise.. But he's pushing pretty hard there. Notice his accuracy went to crap too.. I'm running 42.5gr of RL16 with 140ELDs and getting 2958fps from a 30" barrel. Not a hot load at all, and shoots 1/2" or better. By contrast, same 140 with 42.5gr H4350 I get around 2918fps.

So my goal is simply to hit 2800 with my 22" barrel. Do you think that's possible without burning out the throat quicker than normal? This barrel prefers the hotter loads of H4350 so I'm hoping it maintains accuracy. I'm only able to get about 2740 with H4350 before I start seeing ejector marks though.

from what i've seen, RL26 seems to be the speed queen. might wanna look for some data on here or elsewhere
i've seen some 147s pushed from 2850 to 3050 (most settled around 2900-2950)
since you're looking at the 142 and 150 in this article they probably have the weight to benefit form the slower powder (R26), though i've seen a few fast results with the 140s

No experience with RL16 but my understanding is that it's temp stable RL17. I shot a good bit of RL17 in 6.5 creedmoor with great results, and yes it does give substantially higher velocity than H4350 (80-100fps was my findings). My experiences regarding accuracy was very positive, everything shot great. It was temp sensitive but consistent (1.4fps/degree).

It's a double based powder so it's going to torch a barrel quicker than a single based.

I am running it in a 23.5" Bartlien with Peterson brass, CCI 450s, and 143 ELDX, 140 RDF, and 140 ELDM. I ran the 143 ELDX with 41.6 when the barrel was new, switched to the RDF at 200-250 rounds and had to reduce my load to 41.4. I am getting 2810 and sd of 6 so far. I ran some 140 ELDM saturday and got 2841 and a sd of 4 with 41.4 seated .020 off the lands. They shot good at 100, but the mirage was really bad. Not sure what barrel life will be, but I am just under 600 so far. I am 1/2 moa or better with all 3 bullets when I do my part.

I have similar findings to the above post by 260284. I'm running H4350 w/ a 142gr Sierra Matchking.

*Note: I was getting higher velocities in the Starline brass as opposed to the Hornady Brass.
A more detailed comparison of Starline Small Rifle Primer Brass vs. Hornady Brass can be found here.
I'm running a 24" Ruger Precision Rifle in 6.5 Creedmoor.
Bullet: 142gr Sierra Matchking
Brass: Starline Small Rifle Primer
Primer: CCI 450
Velocities: 2667fps @ 41.5gr H4350
Location: Houston, TX
Altitude: 177ft
Avg Density Alt: 400-1400
