Thread: Benchrest shooting- to hold or not the forearm depending upon recoil value?

  1. #1

    Default Benchrest shooting- to hold or not the forearm depending upon recoil value?

    In my reading, it appears the general consensus for best/consistent groups is to to

    hold onto the forearm as it sits on the forward rest for "heavy" recoiling rifles. Can

    anyone suggest where the transition point is from letting the forearm sit on the front

    rest by its own weight or to grasp it with the off-hand .270 Winchester,

    .308 Winchester, .338 Win. Mag. What has your own experience

    shown

    To simplify matters, assume rifles of average weight for their cartridge, not some light weight mountain rifle. Myself, I normally hold onto the forearm as this is what I would be doing from a field position.

    Thank you

    You want no hold on anything. The rifle should rest in the front bag, and the same for the rear. It should recoil freely at the shot. if you are a right hander your left hand should not be on the rifle.

    here's some info from some great shooters. http://www.benchrest.com/FAQ/6.5.shtml

    A decent bench rest set up is a nice solid heavy front rest, and quality leather rear bag. The rifle just sits in the leather bags firmly enough to limit movement while you lightly grip, and squeeze the trigger and should slide smoothly to the rear during recoil. No clamps, or vise type rests, they are gimmicks, and you will not be clamping anything in the field.

    I use the bench rest set up to work up loads, sight in scopes and general accuracy testing. Once I know the rifle/load is dialed in then I can start with field practice. The bench is the place to see what the rifle can do, then practical shooting positions will tell you what YOU are capable of doing, two entirely different things.

    here is my set up with a 308 in the bags. Cowan front rest (built by a HS Shop class) and protektor front and rear bags filled with heavy sand.

    There are numerous factors that will determine the proper hold for a rifle. I can get by nicely with my 300 WM just grasping the rear bag with my left hand and allow the rifle to recoil normally. My 338 WM needs some support on the forearm or else the recoil will lift the rifle off my rest resulting in several scenarios, all of which are less than optimal. Heavier recoiling rifles amplify this effect.

    Sounds to me like you are trying to use a sporting rifle in a bench-rest application. In 100-200 Bench-rest competetion most rifles are small caliber up to Hunter class which requires the case capacity of the 30-30 and minimum of 6mm bullet and a 6x scope maximum. These rifles are fired free recoil and the left hand is used only to work the bolt or load. The leather sand bags are powdered with a friction reducing powder to insure that the recoil is smooth and bags don't alter the recoil of the rifle from shot to shot. The forearms of bench-rest rifles are flat on bottom and limited in width dependent on class; as are weights relagated by class.

    I shot this group out of my .338 at 100 yards this week off a block of wood on the bench coverd by my coat under the forearm, my left hand pulling some down pressure on the front of the sling and nothing under under the butt except my shoulder behind it and my 4-12 scope on 4. Not the tightest group I have ever shot, but is more "consistant" with real life hunting conditans. Sure I can shoot that same group at 250 yds off a lead sled and the scope cranked up, but thats not much good since I really just want to know that I can kill a critter at that distance. Dont need win a shooting match...Dead critter is dead critter no matter how tight the groups off the bench at the range...DSCN0483.jpg

    There are many ways to skin this cat.
    As stated above, this is what I use to dial in a rifle. I have used this set up and technique for .22lr up to 375 H&H mag. Heavy recoiling rifles do not feel good off the bench, but this is still the best way I have found to test accuracy and tweak. I go a bit more in depth on accurizing than most, gunsmithing, and fine tuning are my other addictions.

    I really like to see just how accurate a rifle is. This just eliminates as many variables as possible for me, a rolled up jacket or back pack work too.



    I do not think the OP was looking to use a sporter for a bench rest match, simply asking for bench technique. The same principles apply weather its a marlin rimfire, winchester sporter or a 15lb 1000yd bench gun. of course the front bag will fit a sporter or varmint forend rather than a 3" flat bottomed bench style forend.

    Nice shooting Mekaniks!

    Like AKmik suggests the less contact the better usually but some of the heavy recoilers - like 12 ga slugs - require a little thought before you eat the scope. I have tried many ways and hanging onto the sling is one of my favorite choices, have laid hand on top of bbl with good results also - consistency is the key....

    The only rule is there are no rules to follow. Every rifle is different and repeatability is the key to accurate shooting off the bench once you found the technique that works for you and your rifle.

    For example:

    Rifle is a Win 300 WSM sitting inside a bedded McMillan stock. No matter what I could do 2.5 -3 inch groups were the best I could do. Someone suggested to me that I place my right hand (I am a lefty) on top of the scope to hold the rifle in place. It worked.

    Rifle can require no contact other than the trigger being squeezed to extremes such as holding them in place. Experiment and shoot a couple of groups exactly the same before moving onto another method.

    Randy, Thats how I hold my rifles off a bench works well for me. PM me your 300 WSM loading data please. Kurt

    Smokey is right. Consistency is the key.

    30-06 & 7 Rem Mag class of cartridges and I can do the benchrest hold. Get my .338 on the bench and I'm D-U-N done after three or four that way. Have to hold the forearm with that one and even then it's no fun. Thankfully I did my load development 6 years ago when I wasn't such a candy*****!

    I'm assuming you're talkin about shooting your rifle from a bench, rather than BR competition, with a rifle and rests designed for that competition.

    I started holding onto the forearm a few years back, because I THINK it helps me to get better groups.

    whatever everyone else has said holds true - there are no "rules" EXCEPT do it the same way each and every time - at the bench you are testing the rifle, NOT your shooting prowess

    I also believe in consistency. My 8 lb. .338 Mag. with the Bansner's stock and 250 grain bullets needs a hold on the forearm other wise it wants to jump around on me when I shoot it. If I was shooting it in the field I would be holding some place on the forearm and it would not be jumping around at the shot. I want to duplicate my field shooting positions as much as possible from the bench yet I still want those small groups a bench helps provide, it makes me think the rifle is capable of small groups from field shooting positions, even if I'm not. If I was shooting a light recoiling rifle with a flat forearm and a soft and heavy front bag then I would not need to hold the forearm.

    Oh Yeah, I agree with that.

    I think it was when I got my old 338, that I noticed holding the forearm made for more accurate shooting.

    I don't hold the forearm and I get pretty good groups when shooting off the bench. I also only use a bag for the forearm and a smaller bag for the butt. The rife rest free of any of my body pressure except where the butt engages my shoulder and I don't grab and hold the grip tight with my shooting hand.

    I have noticed "side pressure" on the forearm is a no no. One time I had a bag on the front and I applied pressure to one of the "ears" of the sandbag to help steady the recoil and I eneded up with a very consistent group off to one side of my aiming point...

    when i am working up loads or checking to make sure the scope is dialed in i like to use my lead sled to take most of the human error out and when shooting 30 or so rounds of 375, like this weekend, to remove the felt recoil. i'm sure i would have been punch drunk waaayy before i worked through all of my loads. while practing, it's nice to try field positions like prone over a daypack, standing with rest and standing freehand.

    I prefer to not damage my rifle and work on shooting good so I don't use a lead sled, I want to know what I can do and how well I can do it.

    have you damaged a rifle? i have used one for nine years now and i'm not sure if i have just dodged a bullet or not? it seems to work great with eliminating my error while checking zero, then i also shoot for fun and practice without it. i think i will do more damage to my shooting sitting behind my .338 or .375 for 20-40 rounds while working up loads and also possibly develope a flinch.

    No I have not damaged one of my rifles nor even used a sled to hold one of my rifles, because I do not want those forces transferred to any of my rifles. It is only what I have seen with a few friends who used the sled to hold their rifles over a period of time. One had a stock crack (wooden stock) another had to have his rifle re-bedded to regain accuracy. I don't have issues with recoil and my position at the bench minimizes the abuse the rifle can dish out to my body. As far as the sled is concerned, it is just a thing with me and my desire to not subject my rifles to forces of being in the sled. If it works for you and you are not having, nor had any issues, then certainly you will continue to use it. I do feel though, after a while, there will be a residual effects on your rifle over a period of time.
