Rest base idea...

Has anyone ever tried a 4 leg front rest base? Instead of the normal configuration triangle base I am thinking more along the lines of a diamond shape. I ask this because when I am really trying to shoot my heavy gun fast I sometimes make the rear rest leg bounce just a little. Is 4 contact points on the base even legal in Ibs 1000yd Br. My front rest is pretty heavy, if I am just shooting I never notice the problem, it is when I am really hammering them down range for record target.

What Kind of Rest are you using ?
On my Sinclair Comp, I added a triangle base that I built out of 1/2" plate stock that is about 3 1/2" larger all the way around. - This upped the total weight to about 65 Lbs. And I've added some rest tops to be able to shoot a 8" wide forend (Maxi-Tracker). - Things are rock solid when I add a couple of 30 Lb. bags of lead shot at a couple points on the rest.

As far as a 4 point rest, I'm not sure what the IBS rules state regarding number of points on a rest. - I also have a Ransom SL Mega-Rest & both the front and rear rests are 4 points of contact. - Very stable & suitable for running a big gun on it. - I've shot a 108 Lb. Maxi-Tracker in 50 BMG Imp. & she's fine & I just weight the sides with some bags of lead shot.

I am running a custom built rest with an 8" top my heavy gun is around 60lbs. I have looked at adding weight to the rear of the rest but it would get in the way of my controls. I was thinking a 4th leg in front run down just to take the slack out so to speak.

Rest. A front rest sand bag shall support the front part of a rifle: a rear rest sand bag shall support the rear part of a rifle; neither rest may be attached to the bench, the rifle, or to the other. They must be movable in all directions independently of the other. Any part of the rifle resting thereon must maintain one half inch distance from any part of the rest holding the sandbag on which the rifle rests. Wherever the rifle makes contact on its sides there may a maximum one half inch in height and a minimum of one half inch thick on each side. This does not apply to any devise holding the sand bags in place or any fore-end stop. Sand bags on front rests must be a minimum of one and one half inches wide from the direction of the muzzle to the butt stock and rear rest sand bags must be a minimum of one and one half inches wide by three inches long. Multi-piece front bag systems are acceptable as long as they meet all other criteria listed in this definition. Only “Heavy Guns” are allowed rear rests that utilize mechanical adjustments. Rifles will be removable from their front rests without lifting any part of the front rest from its contact points with the bench it is occupying.
 
It is almost impossible to get 4 legs leveled on a concrete bench. It will hinder you more then help. I had four on my mechanical rear rest, almost impossible to get the screws adjusted just right. I put it on a plate with three legs and the problem disappeared. Lay a bag of lead shot to your rest leg or plate. You could never adjust your rear leg for elevation changes with four. Matt

These rules depend on which organization you shoot with. NBRSA had major changes Jan 1st. I even think some of these are not current. Matt
 
I shoot Ibs there are two other sections I saw nothing about number of legs in it. I didn't think about not being able to get any elevation using the rear leg with 4 legs. Because I do use it from the bank to the targets.
 
There are some other things you can try to help. Use something softer on your stop to cushion gun. I use soft rubber tubing. I also made a stop and screw it on to my stock. The stop hitting the back of your top doesn't have the leverage of the stop on a rod out front. Matt
 
I am using one screwed into the bottom of my front tracking plate, to touch (hit) the bottom of the top just under the bag.
 
Honestly I really don't feel like it is hitting hard and it doesn't pick the rear leg up. I am just trying to do all I can think to get it to track the best it will.
 
I guess I will just have to figure out how and where to add some weight in the rear that doesn't get in the way.

You might want to consider filling some Protektor "brick" style bags with some number 8 shot. - They are pretty heavy and are thinner to where they might not get in the way. - put them just forward of your rear leg screw on each side. - You can get probably 20 lbs. of No. 8's into one of them. That'd give you another 40 back on the rear of the rest.

Thanks for the idea.
 
i am not being a smart azz, way too many people look at the symptom, and never get to the problem. make sure that you look to see what is causing the problem rather than add a leg to stop it.
in my case my base was too light for my gun , when i went to a heavier base, the problem went away.

No need in being a smart ass, that's why I started the post was for ideas not insults.
