Bipod "bounce"?

[ctshooter]

My friend Matt and I were talking about bipod vs tripod while at the range a week or so back. I was shooting my Alpha Wolf with .30 barrel with a bipod and rear support. Matt shooting his new .30 Ghost off a tripod. Both shooting Zan 56gr pellets in the 880-890 range. Barring the electronics vs manual factor between this two airguns I feel they are essentially the same. Both use the exact same barrel from Daystate. We were both using a STO Falx for moderator.

At 50 yards we were getting comparable groups, but at 100 his Ghost was just able to group tighter.

While shooting off the bipod I found it hard to get any preload on the gun as the bipod legs would just slide forward a bit. When I would take a shot I could just tell in the viewfinder there was more movement than I wanted. Moving over to Matt's Ghost on the tripod I felt more stable with the preload and the shots felt more stabilized with less scope movement after the shot.

For the record, I do most of my shooting at home off a tripod, so I am much more practiced off a tripod than a bipod. I am sure that plays into this, but I started digging around the Googleverse and came up with several videos and articles from reputable PB sites discussing bipod bounce. The description of bipod bounce correlated a lot with my experience. The surface of the bench at Matt's range is wood covered with 1/4" foam - kinda like the indoor playground tiles you can buy for kids. The benches at the public range I frequent are wood.

This leads me to a bunch of questions, and I wonder if this is inline with what other experience:

• Has anyone experienced bipod bounce? If so, what have you done to resolve the issue?
• Is this really a thing off wood and cement surfaces?
• Would weighting down the bipod (maybe sandbags on the sides) help?
• How do you get some preload on the bipod when the surface allows movement and slippage?
• Is there any proven track record that bipod/rear support is more accurate than a tripod off a bench?

If possible.. when you noticed that with your friend swap pods and see if he then has issue and you dont or a change for better or worse .. being pcp would not figure tjat being so bad as a springer would bounce from that recoil action .

With my springers i "fluff" my rest as i shoot so the stuffing dont compact and go hard to help shot bounce on one.

 

[ctshooter]

Yeah - we'll have to do that next time. We are shooting close to 100fpe in .30 so there is a bit a bounce, not springer bounce - but we're talking PCPs, not dual recoiling springers, so hard to make that comparison.

I would think a tri at near balance point of gun depending would be pretty stable vs a bi. That 3ed leg adds a bit stability..
Got to help in any fore and aft movment.

Guess should ask if the pods used are fixed or rest types



Tri stability + a rest pad you can find a good pad to use in it

I've had some of the best groups of my life just using front and rear lead filled bags, hard to say what's best because each shooter is different in what feels right to them. I do know from what works for me I tend to get better results from a bipod being moved as far forward as possible, especially so with heavy calibers.

I played around on front bag fill material looking for that just serms right cushioning. Still afyer so many shots it settles and firms / compacts so that's when i " fluff" it. Ended up back with a old tee shirt follrd nice stuffed in a sock. Tried and true ..lol

In my military experience, sandbags made the difference hitting the target(s) with an M60MG or with Ma Deuce. Bipod with the former and tripod with the latter. Very little shift with either but a heckuva recoil if properly secured.

This would do me ..

MTM Quick Rest Shooting Rest

MTM Quick Rest is a lightweight, simple designed front rifle rest. Ideal for checking your rifle at hunting camp or at the range. The rest is...

Looks plenty stable and cost dont hurt feelings if you " improve" the cushion part to your specs..

 

[CTAirgunner]

I always angle my legs on my bipods forward, or rearward. Depending on the surface I have at hand.

If angling them forward I dig in, if backward I put a pull on the rifle back toward my shoulder. I find that when I have the legs 90* (sometimes this is inevitable) that I get much more movement at the rear of the rifle.

 

[Hateful McNasty]

I just got to figure a tripod stability and a good forend rest on that a guy should hold pretty steady.. the bipod maybe more convenient being you can mount it on the gun a fold it up or unfold as needed. Overall in the end you just buy and try things and conclude whats ends up best for you or the shooting area need.

You never said if this was off the bench or on foot / feild use.

Yes - it was noted in the first post.

The surface of the bench at Matt's range is wood covered with 1/4" foam - kinda like the indoor playground tiles you can buy for kids. The benches at the public range I frequent are wood.

Was hoping more competition shooters would give some feedback here.

Excuse da out a me , and sorry i dont meet your expectations.. lol wow

It's a shame when a serious question from the OP ends with a reply like that.
Folks with a lot to say, deter those that would actually want to contribute to the thread, forum.

Perhaps I don't meet any expectations, perhaps I was optimistic about a fair forum and expectations.

Thoughts guys,?

I'm no way trying to be provocative, more interested in what way this forum wants to progress.

I think the way people talk and the way things get printed can sometimes get confused and come off as abrasive, that's my case at least. Haha I don't think anyone is intentionally trying to be rude but it can happen.

That I understand, perhaps I'm incorrect to have posted a comment.
That's my misunderstanding. I'm happy to learn and understand.
Some folk have large voices, dominate a void.
I'm just sorry to hear it so early in a infant forum.
Bye guys, good luck.

You totally misunderstood - and maybe my fault for combining the responses, but still an uncalled for response.

I was responding to your comment about not saying what I was shooting off of.

THEN - I added - that I was hoping those with more competition experience, shooting off benches at targets, would have shared their experiences in the thread.

I am truly sorry they got mixed and came across as a knock at you trying to help out. Totally NOT my intent.

100% Dana. My statement was not meant to insult and was two totally separate thoughts. I think it happens a lot now. Text does not properly indicate inflection or emotion and things can be taken the wrong way much more easily than on a video call or face to face. Happens between my wife and I all the time.

Well in my case, spelling and punctuation doesn't help my cause in trying to sound like I know what I'm talking about. In person is even worse because I'm deaf and have a speech impediment that causes me to sound like I was dropped on my head a few times.

i use to do high end pro Audi artcles and the young lady that did my editing was always call and asking what is this, your going to piss off someone dont use slang that only your neighborhood would know and what is this word or that and youre spelling sucks. LOL
