Hi all,
Im relaoding for my 7m mrem mag and I'm getting a speed of 2660fps and like a laser at 100m.
Is this to slow, it certainly kills stuff.

It shoots nicely out of my tikka, little recoil with a Maniatis suppressor with a brake.
Hey Darryn,
Lots more experienced reloaders out there than me but I used to load for a rem mag. Firs question would be: what do you want to achieve? And second question is what length barrel?
Either way, looks like you're running a low charge weight according to ADI load data so plenty of room for you to safely test some different powder charges if you want to. If reloading is new to you, read some manuals and have a chat to some experienced people before you start fiddling.
Hmmmm that powder charge SEEMS light.....as in that's 130grn 270w load level. But as you say it's accurate and kills stuff. I'm often known to type " many a great load ruined by chronograph" your perfect example of this lol.
Hi,
Cheers for the quick reply. It’s a 24 inch barrel. I want to achieve accuracy with good stopping power. A mate and I were talking about it today, it seems others are getting way faster speeds. I’m no speed junkie, accuracy is key for me along with good case longevity.
Cheers, Darryn
Cheers, I feel the same way about the chrono. There’s a real noticeable jump in recoil even with 63 grains of powder and far less accurate. Like the shots are touching at 100m currently.
Cheers Darryn
Wise fella ( may have been Chinese) was often heard to mutter while pulling beard " if it not broke,don't fook around with it" .
You could likely get up to around 3050 but the gais are largely academic if you have the accuracy you want there. I run same projectile same speed in different cartridge and have cleanly dropped reds over 500m incl big red stag
There is also a current conversation on it here https://www.nzhuntingandshooting.co....-loads-113691/
I ended up settling on 162gr A-Max with 72gr 2217 for just over 3000FPS out of a 22 inch Tika 7RM.
Work up for your rifle. Mistakes can be made typing numbers in :)
Sell it and buy a 7mm08 because that is what you have got. Factory ammo would be faster. Go up in .5gr increments until you see some sort of pressure sign and then come back down a tad and then tune it for accuracy
You should 3 grand with that barrel length and bullet weight. If you can't get accuracy going faster then swap powder or bullet. Worst come to worst you can go back to the slow accurate load
Yes it's slow for a Rem Mag. You can probably get close to 3K if you wanted.
Is it too slow? That's your call.
If it shoots straight and kills what you want it to then I think you've answered your own question.
I've just been working up loads for my new 24" rem mag using 162eldm with 2217 I get 3040fps and 2225 I get 3100fps.
I don't think 4831 is the best powder if you are wanting more speed you need a slower powder.

I made up a batch of super faffed 7mmRM rounds for my mates to play with at the range. Turned the necks, dropped the charge down to about 62 if I recall. But the guys got excellent precision with them and both said it was a joy to shoot. Main problem with shooting the RM full power is that it's a long barrel, fairly tight twist. You will get torque which is OK if you're prone. But offhand? Gonna be trickier than most to keep shooting it accurately
Greetings All,
The Hodgdons data gives 64 grains of H4831SC (AR2213SC) as a max load with the Hornady 162 grain BTSP. This projectile is very close to the one you are using. This is by no means a hot load and should produce around 2,800 fps in your rifle. 60 grains is the Hodgdons start load and your velocity is reasonably close to theirs. Most load data for the 7mm Rem mag was dialled back considerably a few decades back after the change to modern pressure measurement so most loads for the calibre are mild. But as you say your loads kill well and the choice of whether to increase the load is yours.
Regards Grandpamac.
Yeah it shoots well but was thinking it might be running slow. I can always ping back to my slow load if I'm not happy, might try a load with 2217.
Greetings Darryn,
H1000 (AR2217) was like a bolt of lightning when it arrived on the market around 30 or so years back. ADI started making it as AR2217 around 2,000 or a little earlier. Factory velocities could now be achieved without high pressures. H4831SC (AR2213SC) is aa good as it ever was as you discovered if you are not chasing velocity.

So the guys who own land cruisers can't drive to dairy to get an icecream???? And fellas with Honda City should tow boat/ caravan.... Lol it's same old argument....small outboard motors are the same.the 8hp is a 15 under spec d so they last forever.its not working hard so it doesn't wear out as fast.a full noise 7 mm mag can be unpleasant to use. Running it at half throttle,if it does job needed isn't silly. There are a hell of a lot of guys with 3 1/2" shotguns who now run mostly 2 3/4" shells for same reason.
Very slow for a rem mag of that barrel length. I wouldn’t be happy with that as you might aswell have a 7mm08 in that case. I would be working towards more speed. For a 24” barrel I would be happy enough with anything accurate 2900+ minimum.
Cheers, a bit to think about
Couldn't help myself, punched the numbers into GRT and its pretty close to what you are getting. Personally I agree that having an easier shooting accurate load is more important than speed/power, if for no other reason it gives you the confidence of shot placement. If you want more speed you could see if it finds good accuracy at a higher load, but who knows - boat tail projectiles can be more fussy than flat base, right? So it might just open up, but only really one way to find out. As mentioned max. book load with that powder is 64gn.
Cheers everyone food for thought. It isn’t broke right now, shoots like a dream, but always wondered if it was a bit slow. I’m gonna get some 2217 and see how that goes.
AR 2225 works well as well if you are having trouble finding 2217.
I'd take a laserbeam rifle over a 1.5 moa rifle any day. IF you can get more velocity out of it that would be a bonus. But I wouldn't sacrifice accuracy over speed. A slow accurate bullet will do more damage over a fast bullet that missed every time:D:D:D
The handloads that came with my Winchester Model 88 .284 in bought in the 1990's were fine until I chrony'd them recently... :D
When I was using it back in the late 90's could consistently shoot 3-shot groups pretty much touching. Had enough of them I didn't have to reload (not that I went hunting that much). Turns out they are doing a relatively mild 2620fps (150gn). Still killed anything they hit, but all my shots would have been under 200m. Now there does seem to be this focus on speed/range... I guess in general, typical hunting rifles have become substantially more accurate in the last few decades? Coupled with optics for long range shooting.
mate I'm at 2840 out of my 20' tikka with the 162
I'm running 73 gn of 2225
I thought that was a bit slow, and a change to a slightly quicker powder would get it up a bit, but hey it shoots 1/2 moa, and 2840 is more than enough to get the job done
What powder are you using?
ok, probably a bit quick for the long barrel
try 2225
