Benchrest Technique? Pic

I tried somethin' new today with my benchrest technique. Instead of letting the rear bag hold position I just used the front rest and held the rear in my shoulder. It allowed setting the correct cant more easily and provided more maneuverability. Surprisingly my group got better. Can anyone explain what happened? Here's a pic of the target showing 14 shots. The 3 in the 8 ring were the last ones fired.

I'm a right handed shooter and I do better with my rifle in the front rest and my buttstock rested on the rear bag in a way that I can grab it with my left hand with the ears of the bag between my thumb and index finger so I can squeeze them for perfect elevation and hold. I keep my left hand there while I squeeze the trigger with my right hand. Without a rear bag, my groups pretty much go to schitt?

The technique I was using before is about what CampFussell describes. I still had the butt of the rifle in my shoulder but it wasn't as solid as having it held there without the rear rest. Percula may be onto something about the absence of "free recoil" being the key to my RAW. I thought springers were the only airguns that were sensitive to hold. The search for improvement continues ....

i like the techique, better the front rest the better it works,also works well on weak benches when u can't touch the benchtop. all i have to do is watch flags and adjust rest accordingly, i dont even look in the scope for wind adjustments, i use muscle memory with the rest, i know how far the reticle has moved without see the reticle,,,,

LOTS of practice, 


the fire is a summoning flame for the Bullseye spirits....lol

Even my Thomas 0.177 likes a little pressure/resistance. Put a little downward pressure on the "stock" in the natural grip position and things just hit. In free recoil it moves about 5/8", with the thumb on about 1/4". My BM500x 30cal will move back about 1" with free recoil.

It's the impulse. Your rifle is going to move during the time the pellet is still in the barrel. Ideally the movement is perfectly inline with the POA, i.e. straight back no up/down or left/right or twisting. But as we know very small variations at the muzzle will have significant variation at the POI. So it makes sense that the less travel the less chance for variation to be introduced. 

If the barrel is tuned the harmonics will result in a node at the crown of the barrel. The only way the harmonics are really coming into play is if they are effected by pressure points on the stock and the movement of recoil/impulse change the pressure on the stock enough to influence the nodes. IME with my BM500x the "sweet" spots on the fore-end and butt stock are fairly forgiving in terms of exactness. Plus or minus about 1" with the same results over and over again and since my rifle only moves about 1" with free recoil its not a concern. I would suspect that the HM1000x is similar in regards to touchiness of the sweet spots.

Another thought too... With stocks not specifically made for BR with a flat and parallel to the bore butt stock bottom, the rearward movement on a angled butt stock can result in up or down movement during the impulse using a rear bad. I worry enough about the rear bag even with a BR stock that I'm seriously considering a mechanical rear rest.

My technique ( not to sound like i know what I'm doing!) is similar to salticon, I do not touch the gun in any way except trigger,(only shooting.177 for benchrest) I spend a considerable amount of time aligning front & rear rest for best tracking I also spend much time with rests fore and aft on each gun i own to see where each gun likes to rest (harmonics) thats what i like about the RAW guns they seem to have a smooth well damped shot cycle. ( never shot a Thomas, I'm assuming they are similar or maybe better?)

"Salticon"Percula i don't know what your plans are for the Thomas, Some classes are rear bag only. But im sure you know this.Beeser may not thou.

The HV and LV classes state bag for the rear rest, but I'm primarily interested in open and unlimited classes, where I haven't been able to find any definition as to rear rest requirements or restrictions.

The WRABF and ERABSF rule book Sections B.8 through B.11 are relevant here.

It's taken me a while to do it, and I hate fiddling with my Bald Eagle Front rest, so I kicked it to the curb and shot my first ever 250 with attached bipod on front of my measly Thomas with rear bag ears gripped , butt lightly shouldered ,with thumb on back of pistol grip and light cheek weld?



Ken, if you can shoot 250's off that Caldwell table my hat is off to you bro. I see why you have to shoot like that without touching the rifle using that Caldwell table. But one little fart and you're in the 9 ring or worse ;-) I guess I need to buy one of those high dollar front rest, so I can have the patience to use one? I spend or waste way to much time fiddling with the Bald Eagle.

Jimmy, wait to see it if I can shoot 250s off of the Caldwell table then when I get to a real good bench I have nothing to worry about except wind of course ha ha Ha ha ha. I agree with you about the bald eagle it'sa decent rest to get you started. But there's too many variables in that bold eagle I would save up and get you at least a Randolph rest or something equivalent to that. You don't have to have a lot of patience to use a good rest because it pretty much does everything for you.

and congratulations on the 250 buddy!

Ken, if I ever get consistent with 248's, 249's and the ever elusive 250's I would consider getting a Randolf, but I don't compete like you guys so I can't justify it yet. Of course I couldn't justify getting the Thomas either? Just wanted it!
I wish Martin would make a RAW with a swing port like the Thomas has. Makes it super easy to clean barrels and easier to use a little something more harsh in the barrel without damaging or replacing an oring. Also super easy to change out a barrel.

Haha, love to get the Ford and Chevy guys going back and forth and watch the fireworks ;-) Or better yet the Carolina and Duke fans ;-)

It's all good buddy Rapid air Weapons versus Thomas Ford versus Chevy you know how it is we got to get a jabs and while we can 

I can't believe you called a Thomas a ford or a Chevy? Or did you meant it was a Lincoln verses a Malibu? $3,500 Thomas verses $2,000 RAW is a little different?
For 27 years I worked in a nuclear weapons plant and a Thomas looks like it came out of one of our machine shops. ;) For me to be impressed with a "Thomas shooter" I would have to see them put it in a walnut stock! ............ Ok I might be kidding about the walnut stock.
