Home Forums Reloading Big Game Rifles 7mm Rem Mag w/160gr Partitions

Your #'s are off........add 10 grains of RL-26 and you'll be in the ballpark.

I see Alliant lists 65.9 grains as max for that combo in a Fed case. That sounds like a crackerjack load!

Checked my data.

160 gr. NAB over 67.5 gr RL-26 is my buds PG Africa load.

Finger on the wrong button?

Thanks for the correction.

Like hanco I've used 139 to 140's and a few 160 npt's. Last weekend I spotted a pile of 154 gr sp hornady's on a table at the gunshow. I traded the guy a modified bayonet and 45 bucks for 6 boxes of 154 gr sp's. Nothing in that bayo so I got some inexpensive shooting lined up. I'll be damned if I can see where the 154's won't do the job just as good as npt's for the deer I hunt..mb

They should work.

I’m wanting to try Hammer bullets.

Biden made me do it.

68.5 gr R26.

A published load, or a personal primer popper? Asking for a friend.

I used 67.5 gr, as that proved to be a very accurate load at around 3K FPS.

Pharmseller's load isn't over the line; seems to work for him.

To me, RL-26 is about the perfect 7RM powder, although I've used a number of others, several mentioned in this thread.

If I had to chose one, it would be RL-26, although it's not the only option, but is one of the best. IMO, of course....

It’s darned good in my 7 WSM and Rem Mag.

Lots of options already given. I have not tried RL26, but have read that it is great.
With 160gr PTs I have had good success with RL22 (65-67gr should get you 3000fps, my accurate one is 65.7gr fun side of 3050fps), 7828 and 4831. I didn't push 4831 after I got my hands on RL22.

I see a Houston address. You’re probably like me here in LA, unless we travel, our hunting doesn’t include harsh temp fluctuations like some areas. H-4831 is more temp stable than RL-22. I’m replacing RL-22 with RL-23, which reportedly is more temp stable.

In my .240 I use MRP, which I’ve read is a more refined version of RL-22, more consistent lot to lot. Can’t say I’ve proved that, just what I’ve read.

In todays world, you shoot what you can find. A bird in hand….

Of the powders you list, 7828 would be my start with the 160. Rumor has it that 7828 was designed around the 7 rem mag back in the day...

I keep gravitating back to the 175 grainers in mine. Retumbo did good in an ol' tang safety ruger then reloader 22 In the newer ruger hawkeye with 175 grainers.

Did work up a 160 gr speer spitzer load with 72 grains of Retumbo in the Hawkeye that averaged 3048 from the chrono and made one inch groups at 100 yards though....

I remember reading that about 7828.

Several good 7RM options and it’s not a hard round to load for. Guess it depends on what shoots best AND what is available.

To me the top dog is still RL-26, if you can find it. I was fortunate to snag a big jug back in the day.

You are right, not a whole lot of variation in temps, which is why I can get by with RL22, upper 20s and upper 90s are the temp ranges I have hunted in with that gun. Hopefully will get to travel more, but for deer, pigs and nilgai, that load of 160s at 3k has been just right. I have a little 4831, a few pounds of 7828 (also used for the 243win) and 1# of AA4350, but plan on getting RL26 if I see it

RL 22 has worked great for me as well, along with RL26 and Retumbo with 160's.

Shot some 160gr AB's that I had loaded with 61.5gr of RL-19 for another 7rm and this rifle shot them pretty well. About .75" @ 100yds. Not a bad place to be but will still try load work-up when time permits.

If you are running them about 3,050 fps and getting acceptable/stellar accuracy/precision, I'd say you are done. Regardless of what powder you are running. I personally preferred RL25 to get the job done. In 2 of my 7mm Rem mags, I could not get that speed with RL22 and the 160gr partitions. Also got some weird detonation (hang fires) with that powder, that I did not care for. YMMV...

My 700 KS likes 65.5 grns of 7828 with Fed 215 primers in Peterson brass seated .015 from the lands. From experience and research it seems Partition bullets don’t like a lot of jump. Start close to the lands and when you hit pressure you can back out and see if the accuracy improves or not.

Your username have anything to do with Kansas?

No. I’m a lot farther south than that. But I’ve been there.
