I so want to use the AccuBond in my Remington model 700 7MMRM but I can not seem to get them to shoot very well. I can get the Nosler Partition/Winchester combined tech to shoot pretty well out of this gun, but I the AB.

I've been trying the 160 grn with 7828 with the bullet about .030 away from the lands. Any suggestions would be great. By the way I tried some Hornady Interbonds and I had the same issues.

Scope OK? Mounts and everything tight?? I know, same basic questions but you gotta start somewhere. 160g AB and 7828 should be doing ok. How bad are they shooting, what range?? How bad were the Hornadys shooting? Maybe you got a bad barrel from Remington?? I haven't had much problems getting any rem 700 to shoot under 1" at 100 yards with reloads. Try a different powder, and maybe try seating your bullets out farther, like .010" from the lands. Other then that, dont really know what to tell ya. Dont give up to easily. Rifles dont always shoot what YOU want them to, they shoot what THEY Want to.
 
Scope mounts are fine as is the scope. Right after shooting the
AB I shot the Partitions and put four shots almost touching each other. The AB I'm getting one really low, usually the cold bore and then everything else is six inches or so above.

The group size is about three to four inches. The Hornady's shot about a six inch group with the worst of the bouch. I have never had this sort of problem getting a rifle to shoot. It is possible it is the gun, it was used to me and not taken real good car off, but I keep looking at what it shot with the Partitions and I wonder if I'm missing something.

Thanks for the help and any future help. Maybe I need to adjust the trigger it is horible. Anyone here know how to adjust stock Rem. trigger's?

Corey
 
Hmmm, interesting. Shoots the partitions but not AB's. Maybe your rifle just dont like plastic tipped bullets. I've only had 1 rifle, and that was a rem 700 .270 that would not shoot plastic tips. However, it would shoot sierra BT's exceptionally well. 3-4" is definately not acceptable. If you want the AB's to shoot, I would try RL-22 or H1000 or maybe H4831. What primer are you using at the moment?? Rem trigers are easy to adjust. I"m not on my own computer at the moment, but I have a site that tells you how with pictures. Anyone who knows anything about rifles should be able to do it correctly. You can usually get the rem trigger down to 2.5-3# w/out much hassle. That will definately help your group shooting. I would say to scrub the pi$$ out of your barrel from the previous owner. You never know how people take care of rifles these days...I dont like to buy used rifles now adays, but I have, and the first thing I do is run a brush with sweets and get all the fouling out. Your rifle seems to shoot PT's good, so obviously barrel fouling might not be the culprit. Like I said, maybe try 1 or 2 more powders with diferent OAL closer to the lands, and have at it.
 
Scrubbing the barrel was the first thing that I did when I could not get it to group.

I actually started with RL22 first and went to 7828. If you could foward that websigth to me later I would greatly appreciate it.

I guess if I can only get Partitions to shoot out it, it's not all bad. I supposed for what I want if for Partitions would work great. One load for deer and elk.

Thanks for all the help.

Well I hate to say it, but your rifle just might not shoot the 160g AB worth beans. It hapens. I dont mind partitions, but find there expensive for what you get. I'd rather have an AB with higher BC and usually more accurate, for less money. PT is a damned good bullet, dont get me wrong, but for the ranges I like to shoot, the AB or BT is a much better choice, and price as well!! You tried RL22 and 7828 which are 2 pretty god powders for 160g bullets, all to no avail. Just seems lik eyour barrel wont shoot plastic tip bullets is all.

I will forward the address to you or make a link on the rem trigger. I believe the information is on snipershide.com but dont quote me. If anyone else knows right off hand, they might be able to tell you as well. Good luck with everything.
 
Corey. I've found that Retumbo gave me the best accuracy with 175 gr Part. and 160 gr Accubonds. I would also try RL 25
 
I have a friend with a Sako 75 in .300 Win Mag. He has tried 1/2 dozen or more bullets and as many powders and his rifle will only shoot the 180 and 200 grain Partitions. Accubonds, Barne XLC and XXX, Hornadys are all garbage in his gun. The partitions go into such a small group that he has to walk up to the target to verify all the hits are there. You could have a cousin to his rifle, down right stubborn is the only way we can describe it. Recently he bought a box of the 180 grain Winchester XP-3, same garbage as other factory and handloads (3-4 inches at 100 yards) He spent $15.00 on one of the Simms Vibration things that go onto the barrel and the same ammo shot around 1 inch. You might spend more that $15.00 experimenting with different powders and bullets so give that a try first.
 
Friend of mine has had good luck with H4831SC, GM215M primers and the 160AB in his Ruger #1 and his Browning A-Bolt II. Like mentioned above, try different powders, primers, and seating depths. I'm sure you'll eventually find something that works.
 
Sounds like your having issues like I had with my .280, it took forever to find a good round.
However, my 7mag 64.0grains of RL-19 & 140gr A.B.'s are awesome !
 
I'm not sure if I'm reading the topic correctly. The rifle is a 7MM Remingtom Magnum? If that is correct, I had my best results with H1000. It took a while to find the load, but worth the work and wait. It took (2) 6X6 bulls this year. R-P once fired brass, Fed. 215 primer, 160 AccuBond and 72.5 grains H1000.

Good luck approach with caution.

Great advise everyone, thankyou. I will keep experimenting since that is all that I can do, and I guess that is what makes reloading fun. It sure can be frustrating though.

Corey, if your gun prefers the Partition bullet, I just would be happy. There is no bettter bullet out there, in my opinion.

Having said that, the AccuBond is good as well.

The last 7mm Rem Mag that I worked up loads for shot best with the 160 AccuBond over RL 25. I got 3100 fps and groups of under an inch.

AccuBond accuracy is a hit or miss proposition sometimes. When they first came out I tried them in a number of .338 caliber rifles of various manufacture. The first five I tried shot them poorly, very poorly. But the fifth one shot groups well under a half inch several times. You just have to try them to see.

Since then I have had excellant results with the Accubonds in .277, .284, and .308 calibers. ( Except that the 200 grain .308 version shoots lousy in my 300Wby Mag.)

Try the RL 25 with the Accubonds and see if that helps. Be sure to use a magnum primer, I prefer the Fed 215M.

Every gun is a little different. Most of my guns shoot Partitions better than Accubonds and that suits me just fine. However, my latest 300WSM will not shoot Partitions worth a darn but likes the 165 or 180 Accubonds just fine. Go figure.
 
Just reread my post, should have done that before I sent it, right?

I meant to say that the first five rifles I tried the 225 grain .338 AccuBond in shoot them poorly while the sixth one shot them quite well.

Sorry.
 
R Flowers,

I have the Nosler book four, and it does not have RL 25. Could you help me out with some starting loads for the 140 grain and 160 grain if you have it?

Has anyone had luck going with a lighter bullet to get better accuracy, or do you think if it won't shoot 160 it won't shoot the 140s? Plus I'm not sure the 140 is enough for an elk, though. Any more thoughts would be helpful. You guys have been great.

Corey
 
The 140's might shoot, theres just no way of telling untill you get out and shoot them!! The 140g AB will work for elk just fine. Keep it under about 600 yards and you should have no problems what so ever. Granted the 160g is a better choice, but if you want to shoot an AB then give the 140 a try. It will work for both deer/elk, guaranteed.
 
If your gun will not shoot the 160 AccuBond well, I do not imagine it will do any better with the 140 grain version, but you just do not know if you do not try it.

In regard to RL 25, it is pretty new to the market, so lots of reloading manuals do not show it yet. It is a slow burner and better used with heavy bullets. For instance, the latest 7th edition of the Hornady manual does not show its use with bullets lighter than 154 grains in the 7mm Rem Mag. In this Hornady manual it shows a starting load of 59.4 grains and a maximum load of 69.3 grains with 162 grain bullets.

The load I settled on in the 7mm Rem Mag I most recently tested was a WInchester case, a Fed 215M primer, 70 grains of RL 25, and a 160 AccuBond. This is a maximum load and you should start several grains below this.
 
R Flowers,

Thanks for the info on RL 25, I went and bought a pound yesterday and I'm crossing my fingers. Thansk again for everyone's help. My trigger on my Remington is unbelievable now.


Corey
 
this may sound stupid but the interbonds, accubonds, and barnes copper bullets are all longer and require a higher twist rate at 160 grains. I can't imagine that you might have a gun that won't stabilize them but weird things do happen. Try the 140 accubonds as the are just a tiny bit longer than the 160 partitions or try taking the tips off of a couple 160's and shoot them to see if that makes a difference.
