Anybody run any less than Max Max 7RMg loads??

Won a 7RMg Wby VG II SS off GB last weekend in new and unfired condition. Got it in yesterday and it's as clean as I thought it was in the pics, with a sweet trigger that let off is crip at around 3lbs or a scootch less...just a bit over travel to tune out of it after I shoot it a while. 1st one I've ever handled or owned...and totally different feeling than the VG I's and Howa 1500's I've looked at in the past.

Looking for load info on 139gr SST's, 150gr ABLR's, 154gr IB's at 2850- 3000fps pressure levels, using RL 15, 19 & 22, and IMR or H4831SC already on hand and need to burn that stuff up 1st.

150gr Sierra GK; 48gr ; IMR4895 is a very pleasant shooting tack driver in mine. Mimics a 7x57, i.e. hammers deer.

Coyote, I haven't tried the ABLR but a regular 150 AB and 64.5 gr H4831SC with a CCI magnum primer shoots real well in my rem mag. Work up to it though. Nosler shows 65 grains as max. In my rifle it is a solid 12 month load and right around 3000 fps out of my 26" barrel. As for the Hornady 139s, the H4831SC shot decent but it smokes pretty bad and throws an impressive fire ball at twilight. Too slow. A healthy crimp might help, but I don't like to crimp for bolt guns. For what ever reason IMR 4831 did much better. It hovered around MOA from top to bottom with no change in POI at 100 yards(it would be worth a try). For the 139's I settled on IMR 4350. 64 grains makes 3138 fps and it shoots tight in my rifle.

The powder's on hand are left over from other calibers still on hand, mostly for a 270 or 6.5 something and will get used on a remaining 270, 6.5 swede and 7Mauser if nothing else.

The RL15 is left over from a 9.3x62 and probably not a good fit for a 7Rmg..but only about 2/3rd or 3/4's lb left anyway that'll get used eventually in the Swede or 7x57 Mauser.

I picked up this pile of 700+ bullets trading when a guy in northern Montana came out of a 7-08 I think he said that he had hunted elk, mule deer & black bear with, with my plans for using these bullets out of the 7x57 Mauser I'd already traded into ...and was looking at a 280 for something a tad faster...until I could not find a steal of a deal like this 7Rmg was. My skinflint soul was a happy camper on this 'un....so far.
Ron

Why would you go light? I would use the available horsepower or close to the best accurate level. I am loading 72.8 grains of Retumbo pushing a 160 Accubond at 3125 fps. A tad under book max.

With the RL-19 and 22, you can push it fast. H4831SC will be great as well, its not a temp sensitive powder like the RL-15,19,22. I personally have not used the H4831SC in the magnum, but speed will be lower than the Alliant powders.

Tack Driver et al, As I have been reporting for some time now, I have a right shoulder that was surgically reconstructed in '06 that took 18 months of rehab to regain 75/80% of function that is beginning to fail again....and TMI to go into here again. God rang my bell again earlier this week and told me to pay attention to the clock..and the good folks at the HorsePistol here in Dogwood City eased me back into a normal state of health with no permanent damage that wasn't already there. I listened.

As I've said earlier several times I have already sold all of my belted & non belted mags and big heavies like the 9.3x62 and only picked this 7rmg up A. at a price I can sell it for without losing any money,
B. that fits the small mini collection I'm down to fianllay and could be paired with the 7x57 Mauser I'd already picked up to fulfill a bullet range heavier than 140 grains,
and C. when I found some loads that 'gin'ed 2900/3000fps at the very bottom of Nosler's speed range in 150's and up as their most accurate...and I suspect the bottom of the 7Rmg pressure range too.

In the recent past, less tha 10 years ago, light weight smaller calibers like a 270 in max pressures over about 60k have been a problem for me to shoot pad/ no pad, change stocks yadda yadda. This ain't my 1st goat roping, and hopefully it ain't gonna be my last one either if I don't do something stupid to my self again.

I've been down this road before, and at very soon to be 73 early next month, I do not have time to go thru the "fix this again" healing & rehab scenario again....so I am trying to take a short cut to the chase and don't intend to waste any time trying to live like I was 35 or 40 years old again. If I cannot shoot this 7Rmg to my satisfaction somebody will get a nice deal on a cherry clean rifle, and I'll move back to my Swede/7Mauser/7-08 pressure ranges at around 50-52PSI's from just under 58-60PSI's as my Only shooters.
Ron

Good luck on your healing Ron. And good luck with your reduced or light loads. Might look at IMR/Hodgdon loading data for reduced loads.

Wiley, sorry I was not aware of your recent surgery on your shoulder, now I understand why you going light. I wish you well and hope ya find some good light loads for your big 7.

Ron,

I ran QuickLoad for the 139g SST's and a target muzzle velocity of 2900fps. RL15 doesn't show up but the other powders do. This output assumes a 24" barrel, a minimum load ratio of 80%, and C.O.A.L. of 3.29". Of course, remember that QL is just another tool, so work up/use with caution and consult additional resources. I will try to post other bullet weights later when I have a bit more time. Hope that helps. Best, Kyle.

No harm no foul...the event this week was a ear thump to pay attention to the 100pt spread in my BP in less than an hour as proof of the fact that I am not 10 feet tall and bullet proof anymore from the really old days of a 3-4+ year recovery that's TMI for here....but energized me back then to take advantage of learning something new at every opportunity about the people around me and avoid preconceptions.
Ron

TD...when I asked FJG recently for some advice on this same subject, he laughed and replied...when you give a kid a car with a 4barrel carb he's gonna make sure all 4 barrels are wide open everytime he can...my reply was I learned to drive a 4 speed with both feet flat on the floor...of a 1959 VW Beetle ..you make the most out of the tools available to you is the thought process I'm working with...and this old carcass is about done...but not quite just yet. The fun is in doing something that everyone else sez can't be done ...
Ron

KB thx for the QL data...and looks like a road map I can follow for a place to start with the PSI #'s shown in the powders I have on hand that tells me what I need to know about projected recoil. Suprising to see at a 2900fps MV, PSI's can be kept that low.
Ron

You might try some of the Hornady "LITE" factory loads. 7Mag is allot of gun to try to slow down. I would go back to your 7mm-08. Hornady makes LITE loads for it too and it kills VERY dead.

Ive had really good luck making reduced loads using H4895 per Hodgdons instructions.

Its a 130 grain but should work fine with the 139's. If I was you I would trade off the ablr's and interbonds for lighter weight soft point cup and core as the more fortified bullets are worth more and will perform poorly at reduced velocity of reduced loads.



I load one of these in my 270 win using about 36 grains of H4895 and a 110 grain sierra prohuner. It is accurate extremely low recoil and within 100 yards or so does a heck of a number on deer, full penetration through the shoulders or heart/lung of every deer we have shot with it.

RC from everything I'm reading elsewhere the ABLR 150's are real soft and not holding together well at 280 or RMg speeds on elk sized animals...and perfect for my 7x57 at slower MV's on smaller critters.

The better ABLR is 'posed to be the super scarce 168 gr'er for bigger critters at higher MV's. I'm looking at the 7Mauser for 140's & under, and now the 150ABLR's too at about 2650+ tops and will run the 154gr IB's & and some 160gr Speer HC's in the 7mg..and I've got 2 box's of 284 Hornady 139gr Spires that should hit sometime this fall from the Free Bullet deal for buying a couple Hornady die sets couple weeks ago....enough bullets to experiment with all winter anyway. Good thing I joined the Leon County gun Range with 7 day a week sunrise to suset access about 30+ minutes from the house.

As noted earlier I got this pile of +/- 700 or so 284 bullets in a trade for my 260 brass when the T3 Hunter went down the road.
Ron

Coyote, I think I understand what you are trying to do a little better now. In your shoes my starting point would be a 120
Nosler Ballistic Tip and H 4895. The little 120 bt is suprisingly tough for a bt. At reduced velocity it should perform well and be easy on your shoulder. FYI- a .284 cal 139 interlock with a muzzle velocity in the 2700-2900 range is a hammer on whitetail and usually pretty easy to get to shoot.

4895 would be what I recommend. Just don't run a slow burning powder and reduce it down. Hang fires and high pressure from powder detonation could be a problem.

Bear...your comments on 139 gr IL's is good to hear...I got 200 of 'em on th way from the Free Bullet deal on purchases of Hornady reloading stuff.

Chad, thanks for the heads up on 4895...of the stuff I have on hand in IMR & H4831, RL 19 & RL 22 which'd be the best to start with ?

The loads I'm looking at are all as listed in the Nosler On Line Manual in those powders.
Ron

Ron,

Meant to ask...have you checked Hodgdon's website for data? They show a number of good starting loads for 139, 140, and 150 grain bullets using IMR 4831 and H4831 that will give you velocities in the 2750-3000fps range.

Here's the website:

http://www.hodgdonreloading.com/

FWIW, I had good results in a 7mm Weatherby Mag using IMR 4831 and 150gr Ballistic Tips to produce a velocity of 2925fps.

KB yup I have been studying this one too, even before I bid on the 7mg...and part of the reason I was comfortable taking on more caliber than I wanted when I could not find a 280 that fit my budget over the last month or so. Neat site that allows you to select exactly what you want multiple powders and mulitple bullet weights and gives starting level loads too.

I like the Alliant data out of the Product tab so you can pick one powder at a time and look at all the calibers that powder works for. Looking forward to getting into RL26 next spring when I have time to take the time at the range.

I also run both Handloads.com sites for drop tables and recoil estimates.
Ron

I don't think H4831SC will be a good choice for the 139SST. You really want to be cautious with any of these loads on the extreme low end, like Chad mentioned, you don't want a hang fire !

Thx for the info, and hang fire caution duly noted. Looks like I need to change my mailing address to the range's location. That'd certainly be more fun than raking the pine needles and cones to get ready for the remnents of Harvery that is just now coming in as I write this. 100% humidity and light sprinkles starting...and radar shows what I got so far is the very leading edge....dang Weatherguesser said it'd stop at Crockett...30 miles south of me.
