140 eld-m or 147 eld-m?

[Creedmoor shooter]

So I'm thinking about leaving my 140 eld-match for the 147 in my 6.5 creedmoor. My rifle really likes the 140 eld and I have 2 loads that I use for it one being 2885 fps and the other 2946. What I'm wondering is the bc of the 147 really worth the switch? My biggest thing is not being able to push them fast enough to make them any better than my 140s. Has anyone shot both that can chime in with some velocities?

How long is your barrel?
How much case capacity do you have left?
I'm thinking if you have a 24+ And you're not worried about pressure another grain on powder should get the 147s to the same speed. You won't really know without trying in your gun.
I also doubt in the big scheme of things it'll make that much difference. Lol experimenting is always fun though

26in barrel. I run 42 grains of rl-17 and 48 of rl-26. 49 grains gets me halfway up the neck. I highly doubt I'd notice the difference, but then at the same time that little bit could make the difference. I'd like to experiment with the 147 just for giggles though. Reason I'm asking is cabelas has a sale on hornady bullets right now and I was going to order 500 of wither the 140 or the 147. I still have about 400 of the 140s left from my last sleeve.

IMO go with the 147s. Laser accurate.

I'm running 42gn of RL-17 with my 260 and 147s

Friend is running 42gn of RL-17 in her 6.5CM and 147s

Do you happen to have any velocity numbers? My current load is 42 grains of rl-17 and the 140 eld-m

Worked a load in my cousins 6 CM with 147's and RL26, Savage 12FV.

Fastest usable node was from 45.4 to 45.9 gr RL26, settled on 45.6 gr at 2670 fps. Lapua brass, CCI 400, 147 ELD M's, seated .020 off, .0025 tension.

This was with virgin brass and while the barrel was still speeding up. He's just about got all 200 fire formed now and the barrel should be settled. I need to rework this and I'm confident it will shoot in a higher node.

I'm looking for atleast 2850 with the 147 to make it worth the switch over my 140.

42gn of RL-17, Lapua 243 brass, necked up and neck turned to .012, CCI #200 LRP, HBN coated Hornady ELD-M 147

2783fps

175' ASL
28" Pac-Nor 3 groove Super Match SS

I can go faster with no problems.

Of course RL-17 is a little more temperature sensitive than H4350, also faster.

I use rl-17 for its faster velocity and also I can actually fund the stuff. H4350 around here is like finding hens teeth. I'll give the 147s a go. I've shot the 140 and 143 with dual accuracy so I'm not worried about them not shooting well. It appears from what I've read you lose on average 25-50 fps from the 140.

Between the barrel speeding up and getting into the next node, I bet his comes close to that, maybe just over 2800. Seeing how slow it shot the 147's, we were going to try the 140's instead after the brass was all formed.

You can get to 2850 with rl26 with the 147's safely with large rifle primers. The small primers and the slow rl26 isn't a great fit. You will need at least .5 grains of powder to equal the velocity with 4350 speed powders. I doubt you get there with the rl26 and srp. I'm using 215m's and it has shown lower es and sd than 210's. I assume it is because it is so slow burning. I also use a drop tube quite long in fact

 

[Creedmoor shooter]

Well I went ahead and ordered 500 of the 147s. I plan on using rl-17 and rl26. I'm ordering some Peterson brass and my main primer I use is a winchester wlr.
