Why fook around with load??? It seems to be very good if can elimtthe verticle but. With such tight ES it's not velocity related so WTF would you change charge weight??? Until shooting form has been eliminated he would just be wasting components.

Alot of people are recommending to not use their non trigger hand under the butt.
I dispute that as I shoot all sorts of rifles regularly of my mobile bench or ute tray.
In quantifying that I have a rear sandbag that I squeeze to get my aiming point correct and I use (shock horror) Harris bipods exclusively.
All I can say my results do not reflect stringing when I do a lot of validation on my 720 m plate or 100m zero range either.
Loading bipods is also been proven to be a fallacy and I also subscribe to that theory as again my grouping capability doesn't improve with tension on my bipod as it allows for pressure variations compared to been static/neutral loading.
To be fair I also beleive that you shoot how ever you think you shoot your best.
I know when I get shooters to use my technique they can't beleive how steady they can hold their rifle and groups they can achieve.

Yep a bag under the butt, in my experience squeezing the bag with a light recoiling rifle can be very effective. However this is a 300 PRC and holding the fore end with a bag stabilizing the rear is far more effective when done right.

Bipods are fine, when used correctly. Loading a bipod when using a chassis can work but in my experience like you say it adds more variables espywith plastic stock rifles.

What I said was...try it the other way,nothing to loose. It seems to be most logical explanation for his issues. Be interesting to see results lol.

Does PRC stand for Problematic Rifle Cartridge? It appears every second question here is why won't my PRC shoot.

I know a few 6.5prc's that go very well.
Also, a couple of 300prc as well.
I have in my safe a mates hells canyon I am doing load work on and started out with the 230Atips.
Now that's recoil! that's up there as just got an average can on it as well as a light rifle with an nx8 on it.
They are shit triggers, but an after-market spring helps.
I have dropped down to 212eldx and that helps.
It's is not a consistent grouper which is bloody frustrating as hate rifles that don't play the game!
Probably one of the most accurate rifles I have ever seen out of the box was a Rpr 300prc.
It still amazes me how well it shoots!

Firstly I am not an expert but your results are pretty much described by "Mark and Sam" you tube. He does ELR shooting.

Short story is you most likely have an inconsistent muzzle rise/jump.

As others have said, hard surface and bipods aren't a great combo, a bag for a rear rest will also help.

Something that hasn't been mentioned is a bag rider to allow rifle to slid backwards without the butt dropping thereby lifting the muzzle.

He can explain it much better if you are interested.

This ones a bit longer but deals directly with muzzle jump

Does it progressively rise in vertical as you fire more shots or spray them all randomly?

If it’s random - borrow a mates bipod that doesn’t have pod spikes on it and try that. Reading your last post you mention spikes? Off the back of a wooden flat deck this stands out as an issue to me. Especially if you are muscling the gun and loading it up with force.

Gently gently with your shoulder just making light contact with the butt pad and loading the bipod ever so slightly. Thumb wrapped over the stock not resting on top. Light grip holding the stock the shoulder takes the recoil and your rest (bipod with rubber feet and rear bag) ensure the rifle recoils back nice and straight.

Something to consider anyway..

Interesting video.
Bottom line is bipods are not stable tend to move around when firing.

Shortish range only unless you practice a lot.

You need to watch episode of nzhunter where they have dad's n daughters out after tahr..... It's eye opening just how good the" hug yourself" method can be with heavy rifle.

Or a light rifle in that case..

There are two points I want to suggest re shooting position. First you appear to have an accurate load so I would not alter that at all....

If you are trying to figure out whether the vertical stringing is technique or rifle then you need to eliminate your technique to find out if it goes away or not. Sandbag both ends of the rifle and do everything you can to hold it steady. NO MOVEMENT in the shooting position. If the strining still occurs then it is the rifle and not the technique.


If it goes away then change one thing at a time- go from sandbags to the bipod on a softer surface. Then a hard surface. And a sand bag on the Ute. Change one variable at a time to see when it starts to come back. Then that would be what I would address.

As mentioned earlier, breathing while firing can also cause vertical stringing. The fact that the speeds and lateral grouping are good implies to me that it is something that is happening when you are firing the rifle- be it bounce on the ute / bipod

Second point would be it is a larger cartridge...I had issues with my 375 H&H when I had it as the recoil caused me to develop a small flinch. That may be worth considering too..

IF your hunting rifle weighs as much...by all means.

Theres lots of different holds none of them right or wrong. The idea is to get comfortable behind the rifle and be able to manage the recoil. Body shape and injuries etc will make different styles suit different people
