Rl16 with 6.5 creedmoor

[Joefrazell]

Anyone used rl 16 with 143 eldx or 140 nosler c.c.? I'm thinking of starting at 41gr? Not finding alot of load data.

Treat it like H4350. It's very close to the same burn rate. Knowing my rifle, I wouldn't have a problem starting at 41.0.

I use 43.0 grains of it behind a 140 ELD-M in my 6.5 creedmoor. I am getting 2900ish fps out of a 24" proof with an TBAC Ultra 7 on it. RL16 has been magic in my creedmoor. Seems to be temp stable enough to get first round hits in most temps from 0-80 degrees and yields great accuracy.

 

[WildRose]

You'll probably like RL19 or 23 even better. RL 19 is growing on me in a hurry for both the .260 and .375R.

The .260 case seems a bit small for 23/26. My velocities with 19 were a substantial improvement over those I was getting with RL15 and H4350.

Not sure if you ever tried it but RL26 gives a bit lower pressure, higher velocity and a more complete burn then RL19 with same case fill. Not saying it will give you better accuracy in your rifle, just saying it isn't to much for the case.

Here is QL data on RL16 with 143 ELD-X seated to 2.800" using Hornady Case with 24" barrel / would need more info on your set up to give more accurate load data.
I would start low 39 gr and work up.
Not sure if it helps you, I have not personally used RL16.

Doing a search here comes up with data on some 140 gr loads not the ones you want but does give you an Idea. If you search around here and other forums you should find info that will help.

Thanks.

I tried it, I just kept running out of case with RL23 and RL26. While you're running numbers what does it show you for RL 23?

I'd have to go next door to dig up my more recent loads and it's 7 degrees outside with a pretty sharp wind but I can get my numbers later when it gets back up into the balmy 20's. HA!

Yeah it's negative 14 degrees here with only minor 5 mph winds and gust to 7 mph

Here it is with RL23, it seems it fills the case with less powder, I doubt the chart is useful past 106% fill, that seem to be the limit I get for fill with RL26 in my 6.5 CM, but my lot number has a higher ba than the default so I can get more pressure with less fill equaling more velocity.

I shot 120mk yesterday with 100v. This is .2 moa or better to 326yds(lasered distance we had in the pit) 42.0 100V in peterson virgin brass 210m 120MK seated so heel is at the shoulder/neck junction. 4 shots at the 326 was a 4 bullet clover. 3 groups of 4 at one aiming point where covered with a dime at 100yds 2 shooters on one rifle. We have vastly different eyes so we changed the focus ring 1/2 turn or so. No group shift@100yds We shot different targets at 255 and 326.
I loaded these to fireform the brass. I'd shoot these at songdogs but I'll most likely find a 120-130 tipped bullet for that and use 100v.
Temps were 5-0 as the sun set. We shot for about 2 hrs 2-430ish yesterday afternoon. Chrony battery was dead from sitting in the truck all week no data just a guess of 2800fps from the hodgdon load data page.

I am running over 43 gr out of mine pushing a Berger 140 Hybrid at 2876 fps from a 22" Bartlein Suppressed. I have swapped 4 different calibers to the RL 16 and picked up speed with each. Its my Go to Powder

That's great speed!

Just worked up a load today using RL-16 and Hornady 143 gr. ELDX in 6.5 Creedmoor (small primers). I'd say these numbers are pretty darn close. I started piercing primers at 42.5 gr. and was piercing consistently at 43.5 so I stopped. To bad because accuracy started coming in at the top. I'm going to retest 42.0 grains which is as high as I dare go.

Are you running a small firing pin or a standard sized pin?
