7mm rem mag 162 eld-x results?

[dok7mm]

I am also using RL-26 with 162 eld-x in a 7 mag. I was seeing some pressure at 69.8 gr & 3105 fps. I backed off to 69.0 gr @ 3053 fps and it's a lazer. Jump is .030" and CBTO @ 2.730", shooting .2-.3 moa to 600 yds. in 26" Bartlein #3. I took a bull @ 440 yds and it "smother fried" both lungs.

My load is also 69 Gr of rl26 to get 3130 fps. I was using nosler brass and would get some pressure on the odd one but I have since switched to Norma brass and that fixed that problem.

How was weight retention and expansion on that bull?

For those that are using RL-26, are you seeing any temperature sensitivity? Their description says it's "predictable" in various temps, but I don't know what that means in real world velocity spreads.

Because of that, I was going to run with RL-23, but the 26 has me curious, since it gives such higher velocities.

I'm seeing about 1 fps per degree F in my 7mm WSM with RL-26 and the 162 gr ELD-X. RL-23 seems to run about 100 fps slower (but so do most other powders) and it is supposed to provide no drift with temp. I have no problem managing RL-26 given I don't hunt in temp extremes but I do have RL-23 just in case that changes.

funny enough, I was just reading the other thread in the reloading section. Interesting stuff. I think I'll opt for the RL-23 or H1000/Retumbo for more stable performance since MT hunting seasons can be -20* or 50*+ depending on which end of the season you're on.

 

[Varminthunter243]

Yeah I'm in the same boat here in NM. shooting all summer getting drops figured in 100 degree heat don't do me much good when a shot at an elk in October could be 25-40 degrees

Hornady does not list Reloader -26 for 7mm 162gn.
I use Retumbo not only for stable fps but also(mainly)because the round goes where I want it to.

The target doesn't know if its 2500 or 3000 fps . Its not a drag race,its just hit or miss.
The difference between 2900 and 3000 fps with Retumbo behind a 162 A-Max is only 70 yards of terminal ballistics. For me, if its that critical, I'll get 100 yards closer.

 

[Varminthunter243]

I agree haha I wonder how comparable RL22 and 23 are. I would expect same load data? I haven't seen any RL23 around here.

A good Ballistics calculator records zero ing weather and compensates for the weather change.It uses all weather data to achieve a density altitude. (A real time thickness of the air to calculate an atmosphere drag rating. It uses temp, bar.press.,humidity,and elevation to do this. You may be at 700 altitude, but depending on the temp,humidity, and bar.press.,your round may be experiencing a 2500 ft altitude. So you won't have to worry about it. Its called absolute pressure in the app settings.

Burn rate for RL-22 = 0.3860 and 0.4090 for RL-23 with the lower number being slower. So they are not too far apart except in drift due to temp changes where these powders couldn't be more different. I wouldn't use RL-22 unless my only other choice was to throw rocks.

 

[Varminthunter243]

Yeah that's another issue. I live at 6000 feet and hunt anywhere from 6000 to 10,000. But most shots where this rifle would be used are in the 6-8000 ft range.

Because of the temperature sensitivity?

Not with a Ballistic calculator. I feel extremely confident that with a zero in Texas at 425 ft.where I live, I can go to Denver with the same loads and have another shooter hit at 1000 ft with in the first 3 shots.
(I'm not saying this to tute any horn, it the confidence I have in the technology I have on hand to use.)
Technology has completely revolutionized the long range shooting game. In the late 80's everything was paper charts ,trig formulas, and educated wind estimations(guesses).gun)
