7mm 140 Accubond load

[rgalan]

Recently you all gave me a superb load for my 30-06 and now I need a good load for these 140gr AccuBond in 7mm Magnum. Thank you in advance for your help.

[JD338]

RL22

Start 63.5 grs
MAX 67.5 grs
sweet spot should be 66.0-67.0 grs.

Use a Federal GM215M primer.

POP- Whats the velocity usually like with that particular load?? I might have to try that 140g AB load. Everyone needs a good 140g load for a 7 mag in my opinion. I acquired a rem 700 7 mag and the first bullet I am playing with is the 168g VLD. First load tried out of the rifle, 64g RL-22, RP case, Fed 215M, 3.450" shot .35" at 100 yards. Velocity was 2940fps. 65.5g produced 3000fps and .45" group at 100 yards. I stuck with the 64g load and shot a couple at 400 and 700 to check drops. I only shot 2 shots at each distance but they measured 1.75" at 400, and 3.5" at 700. Not to shabby for a completely stock rem 700. Trigger was ridiculously heavy as well. Im getting that taken care of as we speak. I mounted my MK4 on top so it will now replace my 300 RUM as my long range rifle. 7 mag should still do all that I need and ask of it to do. I will be giving full field report on how the 168g VLD performs on deer and a bear if the shot presents itself.

Actually 67.5 gr of rl 22 (Nosler's max load) has never gotten close to 3300+ as advertised---in my 7 mags. Using prudent work up techniques (CHE measurements etc.) I did reach 3350 or so but with 71 grains or so
---again in my rifles.

 

[remingtonman_25_06]

Thats what I was curious about POP. I dont see how Nosler gets close to 3300fps. I've never seen a 7 mag get that kinda velocity unless your to go over the book max. I would then only go over book max if it was shooting better with a little more powder being dumped in. My dads 7 mag is only getting 2975fps with 140g BT, but were using 65g IMR-4350. Accuracy is so good, he dont wanna change.

 

[Bruce Mc]

I get 3300 fps with 69.5 grs of Reloder 22 from my 26" Model 70.

 

[X ring 7mag]

i suppose i have to follow suit. my preference is 65.5 grns of rl22 and a 140 AB. Absolute tack driver from my ruger 77. if you should choose to go with a 150, (Partition or BT) 64 grns of imr 4831 produces the same accuracy. i'm not sure about the velocity, but i'm positive that it's not the advertised speed. someone asked how nosler gets the numbers...one big plus is the length of barrel. i think it equates to about 50 FPS per inch...26" versus 24".

 

[remingtonman_25_06]

I've played with a couple .284" bores in general not get advertised speeds. This coming from 2, 7 mags, and a 7 STW that shot 150fps less then book. It was really slow.

I loaded up a couple rounds at 67, 68, and 68.5g of RL-22 with a 140g BTip just to see what happens. Seems like most are running around this area for powder, getting both speed and accuracy. I'll be testing them in the morning. Hopefully .5" groups and 3250-3300fps.

Who can blame him? 100 or 200 fps would be nicer but what the heck!

 

[slats]

I am using IMR 4350 65 grains with an average velocity of 3220 with sd of 15 fps. groups at 100 yrds under 0.5 inch and 300 yrd 5 shot groups at 1.5 inch and under. my rifle is a rem model 700 bdl of 1985 origin. glass bedded and hand lapped. I want to add a fiberglass stock but I am afraid to change anything since it shoots so well. I can not get 160 gr accubonds to more than 2850 fps and I can only get 1.5 moa with the 160 grain. very sad since I bought 200 of them and the bc of the 160 is awsome. I have not tried retumbo yet with the 160 and hope for the near 3000 fps mark. I guess I will likely stick with the 140 grains even though I am a fan of heavier bullets

 

[skeeter]

Slats have you tried IMR7828 with 160/AB? My rem mag (also a 700 bdl action) loves 66gr of 7828 under 160AB and 215 GMM's. A close second is RL 22 at 64.5gr/215GMM. Both loads top 3000fps and under moa.

I'll second RL22 under 140 AB, was developing a load this year in hopes of getting a antelope tag (didn't happen). 69grs was where I ended at (switched horses due to elk) producing 3200's and sub moa.

 

[Guy Miner]

slats - I had no problem getting accurate loads with the 160's over 3000 fps with either Reloader 22 or H4831... That's from a 24" barrel. With the 26" Sendero, it was even better.

With 140's, velocity was about 3225 fps, but I too preferred the heavier bullets in the 7mm Rem mag. Actually did most of my hunting with the 175's at about 2930 fps... Accurate even at long range and the long bullets penetrate very well.

skeeter, Try the slower burn powders for the heavy bullets like RL19, RL22, 7828. Other selections that I have not used for the 7mmMag are Retumbo, RL25 and are good choices too. Try to make a batch of 5 bullets for each powder you may have on hand. Try seating the bullet on the lands and back out .005 and start from there. Try mild to hot primers, hotter primers may boost velocity a bit more. I use the 7mm Sako with 28 inch Shilen with 140 BT and IMR-4350 for hogs and whitetails and shoots close to .5 MOA with three shots at 300 yards with a mild load of 3050 feet per sec. Accuracy tend to open up a bit if I load hotter but as long as it shoots good, I'll stick with it.I have used 7828 and RL22 for the STW with great results with 140-150 BT's and has devastating wound channels at long range but has a tentency to blow up at short range, velocity with 140's at around 3475 with 28 inch Shilen barrel on Rem. 700 with Sendero stock. As of now, I am having it rebarreled and can't wait to get it back.
I am new on this forum, looks a bit interesting.

Heres an update on my 7mm with 140g btips. My rifle is a rem 700 bdl with 24" tube. I went with what everyone else was having luck with and that seemed to be around 67-68g Rl-22, so I started at 67g. Loaded 3 each at 67, 68, and 68.5g. 67g shot a tad over 1" at 100 yards, velocity was 3150fps. 68g shot about 3/4" and was going 3200fps. 68.5g put 2 bullets into the same hole, and another 1/4" away and was scooting right along at 3250fps. I think I found another great long range deer and coyote getter. Only problem is that damn RL-22 is lot sensitive. Anyone have any recomendations as to waht powder to use with 160-168g bullets to achieve max velocity (3000fps) and great accuracy. Rl-22 is giving me both, but at the cost of sensitivity problems. I was thinking of trying either h4831sc or H1000. I know many have had good luck with IMR 7828, but its an IMR powder and is pretty temp sensitive from what I"ve heard/read. My last can of RL-22 varied 150fps on my 168g VLD loads. The first can was 2940fps and .3" groups at 100 yards. New can was shooting 3100fps and .5" groups. I dont wanna deal with this every time I buy a new pound of powder. Hodgons extreme powder just make sense.

 

[fredj338]

I found the same problem w/ RL22 & have switched to IMR7828. It's a tiny bit slower so you'll need 1/2gr-1gr more than RL22 for the same vel. Accracy is actually better in several carts./rifles than RL22.

 

[skeeter]

I haven't had a problem with RL22, so I'll just keep pushing it in my gun until the time comes, I guess .

2506, 7828 has been an awesome powder for me and other who shoot 7mm rem mags, STW's and 300 wsm/wm. In my case I load it under 160 gr pills, living in Saskatchewan, Canada where it can be -30 we haven't seen any problems with it. Again maybe we're just really lucky north of the 49th.

Brad, must have been a typo I have tried the slower powders, in fact gave loads in both RL22 and 7828.

Kind of funny when reading sites about what powder to use in the 7mm rem mag the most suggested is RL22, so what gives??? This isn't a new thing with the lot to lot talk been hearing it for years just haven't personally experienced it. Not meant to be slam, more of head scratcher!! In fact I posted about the 140 AB in the winter and the overwhelming majority said go with RL22.

 

[Mark]

Are the lot numbers the same between those two cans of RL-22?

[remingtonman_25_06]

Its a great powder for accuracy and velocity, but as far as consistency goes, its got to be one of the worst. On my 2 cans, no they were not the same lot. They were different, thats why the 150fps difference.

I might have to try IMR7828. I was looking at burn rates and it looks like H4831sc, 7828, MRP, N165, or H1000 could all be used as a substitute for Rl-22. There are really close. I'll probly play with h4831sc or h1000 first.

 

[Mark]

N165 works well with heavy bullets for the STW
