Re: Loads for 7 Rem Mag (from Jeffbird)

Does anyone load 7mm Rem Mag w/ 175 SMK and 4831? I have a couple of loading manuals they both say the max load with that bullet weight and that powder gives around 2660 fps. I have loaded to this point and have decent accuracy. However, I have also read other places and heard from knowledgable people that they will load this same bullet and powder up to 2950 fps. What is up with that? Do the loading manuals tend to be overly conservative for legality sake? This is what I tend to think. I guess I'll have to keep on loading and see what I can do without over pressure.

Re: Loads for 7 Rem Mag

Sorry, I should have specified. I was using H4831SC. Highest I went was 64.0 gr pushing the 175 SMK and got 2870 fps. Respectable, but RL-25 got me slightly over 3000 fps before I hit pressure.
 
#13
Re: Loads for 7 Rem Mag

I've got H-4831SC actually. Looking at data from Hodgdon and Lee. Perhaps Lee got their data from Hodgdon. Even if I can push it to 2850, that's still a good deal faster than I'm going now. I'll just have to try it and watch out for pressure. I'm still kinda new to reloading, having done it for about 3 years. Don't know exactly what all the pressure signs look like yet. I know to look at the primers for being flattened as well marks from the bolt face (ejector, extractor). Any bulges or failures of the case are a no brainer obviously.

Maybe I should mention that this is a Rem 700.

Re: Loads for 7 Rem Mag

How about the 160gr. Nosler Accubonds for hunting with some RE-22, anyone have any good data that worked for them? It will be used in a factory Rem. 700 CDL in 7mm Rem Mag.

Thanks,
Chance

Re: Loads for 7 Rem Mag

I am debating between a 6.5 284 and a 7mm Rem Mag. Ballistically, the 7mm has got my eye, but I have been warned about the recoil. How do these loads feel. I will be firing about 50 rounds per competition.

Thanks

Re: Loads for 7 Rem Mag

Got a new Sendero 7mm Rem Mag just broke barrel in with first forty loads.
Got 175 gamekings to group one inch with Magpro 66 grains.

Do you guys have some start loads for the 168 Bergers pushed to the lands. The data in the hodg. flyer is vague.
168gr Bergers
R-P Brass
wlrm
Retumbo Powder ???64?? 68??71??
Any help from some veteran reloaders, very much appreciated.

Re: Loads for 7 Rem Mag

About 2500 at 70.

I just bought a box of Hornady 162gr AMAX bullets. They were recommended on another thread on this site. Much better BC and initial velocity......I'll know this weekend, if the weather cooperates.

Re: Loads for 7 Rem Mag-7 WSM-7-08

For 7mm08:

Note that this is WAY (about 7%) above any published maximums that I've found. Note also that my oal is significantly longer than SAAMI specs suggest.

bullet: 162 grain Hornady Amax
powder: 42.0 grains of Varget
OAL: 2.905"
primer: BR2
brass: Winchester
barrel: 25" Pac-Nor SS Match with 8" twist
action: Savage 10
MV: 2805 fps average (was 2725 when the barrel was new and clean, it may be lower now that I cleaned it and removed the carbon boulder. In any case, MV's were always very consistent in each session)
neck tension: No idea, but I use a full-length redding bushing die, and it resizes a minimal amount. So I guess my answer would be 'not much.'

Enjoy,
Bob

Re: Loads for 7 Rem Mag-7 WSM-7-08

Thanks guys, I'm looking for a good offhand to 500m load with the Seirra 168. I gotta load mag length in a SA 700, so as much as I like Amax's they're out for my purposes.

A benchrester and another silhouette shooter told me to load around 2300fps, and as this would be slow for 600-1000yd does it sound ugly for an offhand load?

Re: Loads for 7 Rem Mag-7 WSM-7-08

7mm08

bullet: 162 grain Hornady Amax
powder: 44.0 grains of H380
OAL: 2.800"
primer: CCI 200
brass: Federal .308 Match brass resized
barrel: Savage 22" 1 in 9
action: Savage 10
MV: 2850 fps average
30fps max deviation

Temp 55
Baro 30.09
RH 11%
wind from 11:30 at 15

It was a bit breezy this morning but it still grouped at .72" for 5. (one was very probably me.)

Re: Loads for 7 Rem Mag-7 WSM-7-08

Taco, any further testing with the H380? I'm currently using IMR4350, but thinking about switching to get above 2800fps. Isn't H380 known to be temp sensitive?

Re: Loads for 7 Rem Mag-7 WSM-7-08

For 7mm Remington Magnum...

You can reach top performance, low velocity spread with 160gr SBT / 168gr HPBT / 175gr SPT weight bullets with Norma MRP and Hodgon H1000. In a 26ic match tube speed go from 3050 fps to 3200fps in my rifle.

There is an excellent article about 7mm Remington Magnum in the 17th edition of "Hanloader's Digest". It will be a very good thing for some people to read it.... the author drive a Nosler 162gr SB at 3160fps and 3088fps from a 175gr Speer from a 24ic barrel with heavy load of H1000.

They'll understand why the 7mm Remington Magnum show some astonishing performances with only few powder... The 7mm RM is a finicky caliber to reload but when you combine right brass, right powder, right primer it's magic...

don't under estimate the of Brass... lot of 7mm RM brass have lower capacity than they should have... Favour quality brass even if the cost is price... Norma Brass have no contender... Lapua, Hornady are right choices too.

7mm WSM
35*F
7500 Feet
180 Berger
COAL 2.965
24" Broughton

63g H4831 2940FPS
63g RL22 3027FPS
67g H1000 3011FPS

All loads were a little hot, not really to bad though. It was freezing and altitude is high. Im going to dial down a couple grains and see how velocity holds up. H1000 and RL22 seem to hold better groups.

Re: Loads for 7 Rem Mag-7 WSM-7-08

Anybody know who else makes 7mm WSM brass besides Winchester?

You guys realize that even though SAAMI says the case length is 2.100", it's only about 2.090. And it hasn't reach 2.1" even after 6 reloads and without any trimming. What's up with that?

Re: Loads for 7 Rem Mag-7 WSM-7-08

Paoers Ive noticed the same with my brass. Still 2.090 after 2 reloads.

*********
My 180 berger loads were smokin hot, dialed em down a little. here is what I came up with.

7mm WSM
35*F
7500 Feet
COAL 2.965
24" Broughton

59g H4831 2808FPS (only 3 FPS deviation among 4 shots!)
59g RL22 2828FPS
62g H1000 2785FPS


The 4831 and the RL22 were still way hot. H1000 looked great, could use a little more, gonna try 63g and 63.5g. H1000 shoots the tightest also.
