I want to work up some loads for 140gr. Accubonds over RL22 in my Browning A Bolt 7mm Rem.Mag. for Whitetails.

Anyone shooting this combination (powder/bullet)? If so what kind of velocitys are you getting and what loads are working in your rifle?
 
rws2,
I just bought RL-22 and some 139 gr. Hornady SST Interbonds. I loaded 10 to test with 65 gr. of RL-22 in my 7MM RM. Haven't shot them yet.

My Weatherby Vanguard did not like the 160 gr. Accubonds, so I am trying Hornady.

I think the 140 gr. Accubond, and the 139 gr. SST will be absolutely deadly for whitetails!

Good Luck!
Tim
 
My rifle likes 160gr. Accubonds over H1000. I can push it faster but the load it likes best is at 2960fps. But it shot about all loads I tried 1 1/4- 1 3/4 the 2960 load shoots at 3/4" if I do my job. I've taken several Whitetails with that load.

Just wanted to try some 140s and if they don't work I can fall back on my 160 load.
 
I shoot 140gr. Nosler solid base in my Vanguard.63.5gr.RL22 with 215m Fed. primers. Bullet at -10 off the lands. This is a great load for my rifle. I get groups under 1" and some as small as 5/8". I shot a antelope last year in Wy. at 244 yards. Would have taken the shot out to 400 yards if I needed to.

I use 139 Gr. Hornady's in both of my 7MM Remington Magnums along with 71.0 Gr. of H4831 (See Hornady VOL. II) 3400 fps + or - some change. Both shoot under an inch consistently.

I was under the impression that the SST is not a bonded bullet? I'm using the old technology bullet InterLock™. The level of performance is DRT. Deer and antelope are easy to kill and do not require the bonded technology.

I have killed Mule Deer with this load to 500 + yards.

Not the AB's but I use 140g NBT's in my 7 RM with 68.5g RL-22, R-P case, Fed 215 primer, OAL= 3.350" Shoots .3-.5" at 100 yards, 1-2" at 400 yards, and right at 3250fps. Excellent long range coyote/deer getter.
 
Jay Johnson- Have you cronoed your 139g loads?? Just curious. Book velocity and actual velocity can vary quite a bit, especially in 7mm bores.

I think Hornady's and Noslers ballistic guys are on something... Theres no way a 7 RM is going to get 3400fps with a 139g or 140g bullet. 3300fps is pushing things, but 3400?? It might be achievable in a 30" barrel, or on the highest end of pressure, which isn't a smart thing to do. Even look at the Nosler manual, they claim 3340 or some BS, theres no way. There using 65-66g of RL-22 to get that, I"m using 68.5g and only get 3250fps, so nope, no way possible. Talked to many other people that use RL-22 and there lucky to break 3300fps and there up around 70g. 140g at 3400fps is 7 STW territory...

Yes chronographed with my Pact 1 in both 24 and 26 inch barrels. I get over 3400 fps in the 26" barrel and 3350 out of the 24 inch barrel. It has been my deer load since 1975. It has harvested deer from 35 feet to just over 500 yards. They have all been one shot kills. As I said you can document the load in Hornady Vol II. Work up to MAX slowly I'm a few tenths under MAX. Your mileage may vary. My STW will shoot the same bullet near 3550 with H1000.

Sorry!! Used the wrong terminology, had a senior moment when shifting between manufacturers! Jay is correct, it is an Interlock!

I shoot the 140 Accubond with the RL 22. I'm shooting them with 65.5 grains with Federal Magnum primers in RP casings & have shot some nice 3 shot groups with all being covered with a dime. I also shot 3 deer with them last year & they expanded & worked great. This will hands down be my deer load for a long time.
 
Have you got a chance to crono your load??? Just curious because I see a lot of variation in charge weight/velocity with RL-22 and 140g bullets in the 7 RM. I know theres many things that factor velocity, but I guess it just depends on where you look for data also.

I used 68.5g for 3250fps according to the crony cronograph, I know not the best but.. Anyways, I was shooting at 800 yards for the first time with that load. IT called for a certain amount of MOA and I ended up being about 3 MOA low. Now either my velocity isn't really 3250fps, or the BC of the 140g NBT really isn't .485, or my Leupold VX3 LR 6.5-20x50 scope isn't really 1/4" clicks. Now I worked out this whole ordeal and I'm gonna just say I dont really know what to believe as far as velocity. I've talked to many people that shot this bullet to 700-800 yards and they said it was pretty dang close to being .485. For me to be 3 MOA low at 800, my BC would have to around .350 for the 140g NBT. I doubt its that low. However, I"m only 700ft above sea level...To the next problem. Velocity says 3250fps, if I was hitting 3 MOA low, my velocity would only be about 3075fps, indicating my crony is giving false readings. I was also told to check my scope to see if its giving true 1/4" values. I did this by dialing up 20 MOA, or 80 clicks at 100 yards. I should have hit 20" high from my aiming point, well I hit 20.5" so my scope was pretty dead on as far as clicks. So what did I gather from all this?? 1 of 2 things, either my crony is broke and im not getting 3250fps with a 140g bullet, more like 3075fps, or the BC of the 140g NBT isn't .485 and closer to .350 in my area under my conditions. All I know is that it doesn't shoot as flat as it should, I'm kinda dissappointed, but its pretty accurate so I think I"ll just stick with it.
 
Also forgot to mention I did another check, this time for actual recorded drop. This is actually where I believe my velocity to be 3075fps, based on this test, instead of 3250fps that the crony says. I zeroed my load at 100 yards exactly, dead nuts. I then took aim on my 400 yard wall paper and held at the top and fired 3 shots. I wanted to see how far they dropped at 400 from a 100y zero. According to the program, I should have only been 20" low at 400 yards. Well low and behold I was 23" low at 400 yards. So already starting to shoot low at 400 would make me shoot way lower at 800, as I found out. For me to be 23" low at 400, velocity would have to be 3075fps. When I shot out to 800, 3075fps matched up quite well. 3250fps was hitting low at 400 by 3" and was hitting about 12 clicks low at 800.

Damn, those are smoking for a 7. I might have to try and work up around that with the 140g NBT and see what happens.



I have used the NBT with the load and they are pretty accurate but the Interloc is a little tougher bullet and with the higher velocity and my good results I stayed with the Hornady.
