Hope someone here can help , just recently got the rem. 7 predetor in 22-250 and am at wits end trying to get this thing to even come close to shooting a half decent group!
dont know what else to try? stock out of the box with factory hornady 55 gr. v-max maybe a 4 inch group so went to working up a load and started w/55 grn. nosler bt and varget powder started from 34.5 grains and worked up to 36.5 grns. seating depth from 2.350 all the way out to 2.515 ( best was seated 2.500 )never could get better then a 2 " group w/ fliers always out of 5 shots. read on here about the front preasure points on this very cheap stock and relived those and floated the barrel all the way to the the action. worse results! so i changed to H-380 powder with same scattered results? am i just using to light of bullets for this 1 and 9- 1/8 twist barrel? tryed a few 60 gr. grain nosler and havent tried those extended out yet but were terrible at 2.350, measurment to the the lands is 2.528 any one have a sugestion would be great as a gun show is comming up this weekend and would be a good time to dump this headache!

i have a rem.700sps in 204 that did the same thing.i tried different loads and bullets but nothing worked like i wanted it to. i floated the barrel and the groups grew bigger.i decided to do something that i do to my ruger 10/22's when they wouldn't group like they should. i put a piece of rubber at the end of the forearm under the barrel and middle way of the barrel. my groups went from 2-3 inches to 1/2 inch groups. i was like you and was ready to sell it as soon as i could find a buyer. now I'm glad i didn't. you can get the sheets of rubber i use at Lowe's in the plumping section.its about the thickness of a business card. hope this helps.

Hey Larr
Thanks for the response, so what does the rubber sheet do? is the barrel contacting the rubber and cushioning the vibration?
 
Just out of curiosity I have a few questions.

Does a loaded round chamber as easily as an empty case?

And are your action screws tightened enough and even?

I had a rifle with these same issues. It wasn't a remmy, but the problems would have the same effect.
 
Im only neck sizing the brass as i always do after its shot in that rifle there isnt any tight bolt problems after cartridge is fired, action has been taken off and on stock so many times but try and torque it down to 30 lbs and even
(model 7 only has 1 action screw and one smaller back trigger screw , which is dumb)

it seems to bed the barrel as it were and dampen the vibration. it works on a sporter barrel,never needed it on a bull barrel. it was the first time trying it on a centerfire rifle always used it on a rimfire. i said what the heck might as well try it, it couldn't hurt and to my surprise it worked.
 
larr is dead on. It is all about harmonics. I am the guy who initially started the thread about the Model Seven Predator pressure points/blocks that were inside the forearm near the front swivel stud. I bought the 17 Fireball in the Predator, it was a good hunting rifle but would not shoot groups due to inconsistent point of impact when shot one right after the other. Todd Kindler bought the same rifle I had, and he did all sorts of things to it before shooting it, bedded, free floated the barrel, trued the action, squaring the bolt face etc.

In reality some rifles need those bedding blocks up forward due to the thin barrels with higher harmonics or vibrations. My gunsmith directed me to do what larr did basically, add to the blocks, not take away. Only he told me to use black electrical tape on the blocks, making them taller, to equalize the pressure on both sides of the barrel. try this,if it fails, buy a new stock. Mine is great for hunting, it will shoot to the point of aim when cold and maybe move 3/4" to an inch hot. Next time I have it out of the stock I will blue the fit to the blocks with chalk or something and adjust accordingly. Good luck.
 
There's an easy way to see if floating the barrel or some forearm pressure will give you better groups and it's non-destructive and can be reversed at will.

Loosen up the action and take one or two thickness's of old credit card or library card and place them just in front of the recoil lug under the barrel. Tighten the action back into the stock. You should be able to do this.

You want to be able to pass a doller bill between the stock and the barrel all the way down to the card or cards. Shoot the gun. Groups will either get better, stay the same or get worse.

If it will now group then use a deepwell socket about the size of the barrel channel wrapped with some 80 grit sandpaper and sand out the channel so you can do the dollar bill trick with the barreled action tightened back down in the stock. Do put some finish such as Birchwood Casey's Tru oil on the sanded wood.

If floating doesn't help, and sometimes it won't then put the card or cards up near the end of the forearm and tighten down the barreled action into the stock.

Often a rifle will respond to about 7 pounds of forearm pressure and Remington factory stocks often have this bedding point already built into the stock so look for it when you have the barreled action out of the stock. Now shoot the gun again and see what it does. If it shoots good you have a couple of alternatives.

You can either just leave the plastic there and simply cut off what sticks up past the barrel and stock or you can get a Brownells' gel glassbed kit and bed in a pressure point where the cards are.

It might be a good time to do a glassbed job on your rifle if it needs a pressure point bedded in, it's not a lot more work to bed the recoil lug in when you bed in that pressure point. Glassbedding usually results in an average 10 percent accuracy increase on a bolt gun and sometimes much more.
 
I had the exact gun ended up sending it back to Rem. could not get better than a 4" group from a vice. still waiting on the outcome?
 
Hey Edp
Was thinking of doing the same thing but had a few friends send away a couple of bad shooting lvsf and were told they were standard when they left and were fine, also dont know what theyed say about my removing there wonderful lugs on the quality high dollar stock they use,LOL
 
I have a Model 7 Predator in 223, and it will shoot 1/2 inch groups all day long. My brother has one in 22-250, and it will do the same. You might have base, rings, or scope problems. I'd definately check that out.
 
yeah i did the scope changaro thing already went from a brand new weaver grand slam to my faithful leupold and still the same, hey GC what does your predetor like to shoot?heavier or lighter bullets powder?
thanks Mark
 
I got mine from my wife as a surprise “just because” gift just as hunting season was beginning and actually have done limited testing. I scrambled around to find a suitable load to hunt with and once I did I quit messing around with it. I'll probably play with it more this summer.

With that said, I shot two factory loads a couple of groups each then went to work with my favorite bullet in handloads. I shot two five shot groups with the Remington 75 gr. Accutip (V-Max) and this shot around 1 ¼” at 100 yards from the bench. I did the same with the Remington factory 100 gr. Core-Lokt and it shot just about the same size groups.

I then went to work on some handloads with the Sierra 85 gr. HPBT and the rifle shot groups that went from 1” to around 1 ½” until I hit a sweet spot and the groups cut easily in half. So far my thought is the rifle has potential to be a really good shooter IF a person takes the time to fiddle with it. My hastily found load will put three under a nickel and five under a quarter with change to spare every time at 100 yards. But it took several loads to find that sweet spot. I'll know more this summer when I have more time to work with it. Honestly, if it never shoots anything else as well as that load I'll keep the gun because I think it has the right balance and feel for a hunting gun for me. I killed two whitetails, two coyotes, a bobcat, and several crows with it so far with one shot each and haven't had a miss yet. I'm on a roll with it and enjoying the gun a lot so far.
 
I have had several 22-250's and from my experience, they are finicky. I have a Tikka Varmint that was a decent shooting rifle with 52 gr. Bergers. I was bored the other day and loaded up some 40 grain V-max with 39 grains of Varget. Figured I'd lock it up or blow it up or peel the hide off the bullet. To my suprise, none of the above happened. Instead, it shot 10 in a little small group. Probably one of the best groups it has ever shot. JMO
 
I wish Remington would quit #$*#&#* around and put the Predator in an HS stock!!! The average hunter(drag it out once a year) isn't buying this rifle. Give us a good stock so we dont have to "make" them shoot after the fact!

Youda man!!
Hey it worked i installed a strip of rubber down the channel of the stock where i removed some material and put two ruber cabinet tabs up where the pads were then tightened down the action , headed to the range w/ a friend who thought i was nuts that this was gona make it shoot as he was there sunday when i couldnt get a 4" group.
36 grns. varget -55 nosler balisic tip (this is his 22-250 pet load ) 1st fowling shot was high and left 1.5 " which was promising 2nd shot 1/2" right elevation on! guess where the next 3 shots went? almost had one nice big hole ! never woulda guessed it. also tryed some 60 grainers and some h-380 that lookes promising but was very impressed w/ the varget its clipping along at 3420 fps.
Just wana thank you guys for the help new youd come through wasnt looking forward to telling wife i needed a new newer gun!!
