What is your prferred lload in your 7 m/m Rem Mag with bullets no heavier than 140 grains (for deer/antelope)? I know your rifle & mine probably won't like exactly the same recipe, but the info will still be useful in working up some good stuff for my gun...

TIA,

Most of the 7 Rem Mags I've loaded for like 150 gr. bullets better than 140s. For them, IMR 4350 has been a good powder.

I bought a Remington 700 last year that does shoots the 140 gr. Sierra Spitzer BTs pretty good but not great. I'm about to try it with Sierra Prohunters (FB). IMR 4831, RL-19 and RL-22 all show promise.

Canuck, if you find a good 140 gr. load before I do, post it.

AC,

The load I've used for the past several years in my 7mmRM is a max charge of RL22 behind a Hornady 139 gr. pill using Fed 215M primers. This load shoots 1/2" in my rifle. This rifle might be a little slow (compared to some other posters) as it chronos at 3150 fps out of a 24" bbl. I use this load on big northern whitetails, and it works very well. thank you!

This last fall, I decided to try something different, and went out and got some factory Rem 140 gr. CoreLokt Ultras at WalMart. All I did was adjust my scope 2 clicks to sight-in and go hunting (never did chrono them, a project for this summer). But I will say that load really smacks a big whitetail. I was expecting pass throughs with that bonded bullet, which I didn't get. What I did get was just a bang/flop on a broadside center chest shot. That big 5 pointer went down so fast, I didn't know where he went! Your results may vary.

My 7RM likes the 150s & 160s better than the 140s but, it will shoot them ok as well.

69 grns R22 under 140 grn Accubond, Rem case, Federal 215 Gold Metal primers gives 3/4moa.

same load w/ 140 Nosler part. gives 3/4 moa

150NBTs, 66-67 grains of R22, Rem cases, and Fed 215 GM primers shoot .4s (3100-3140 fps)

150 Nosler Solid Base, 66 grains R22, Rem cases, Fed 215 GM primers shoot .5moa (3100 fps)

160 Sierra GK BTSPs shoot .5s w/ 66 Gn R22 as well (3080-3100 fps)

140 NBTs w/ 69 grns H4831 give 3/4moa (~3200+ fps)


I have found that R22 gives the best accuracy from my 7RM. Fed 215s also gave the best accuracy, w/ CCIs the groups opened up to 1"+.


Good Luck!

I like H4831 or RL 22 with a 140 gr bullet. I have a 25" bbl and get between 3250 and 3300 with good groups. I learned last year to make sure I have a strongly constructed bullet at those vel. I'd go with the Partition or the TSX

RL22 and 140 gr. TSX's. HTH, Dutch.

Mine does pretty good with the Sierra GK 140gr. pushed by RL19. I used WLRM primers in Rem brass. The powder charge was over max book by several grains.

Incidentally, last year I was working with the Hornady 162gr plastic tipped bullets that were sold by Midsouth on clearance. I really was getting better groups after several recipies and then switched to 160 gr Barnes XLC's and boy did the groups get better! Right up till the scope broke.

The 140gr. GK worked fine on an Idaho buck. Quartering away complete penetration, when it didn't go down in a few seconds I hit it again broadside. Again with complete penetration. The chest cavity was like soup. This was the first time for me to see a buck hit that well that stayed up on it's feet like that! Nate

The 140 Gr. TSX has taken over for the Sierra GK for me, IMR 4831. Excelent grouping, and one shot kills on the TN deer I hunt.

Thanks, guys...all good info. My Ruger No.1 really prefers the Hornady 162 GR. hp Match bullet with H-4831-LC, but that bullet is so long that this new-to-me bolt rifle will neither accept them in the magazine, nor chamber them, unless seated with over half the bullet length into the powder space.

I know Chubb Eastman's latest Rifle Magazine article says having the bullet down into the powder space doesn't alter either pressures or velocities, but I suspect the universe covered by his tests (2 barrels) is not big enough to be conclusive proof of that hypothesis. So, I still don't like my bullets almost falling into their cartridge cases.

Thanks again,
