Fortis adjustable rear rests?

[Ralpharama]

I’m trying to achieve the best bipod/rear bag combo for shooting my new AXMC .338. Currently I’m using a super heavy rear bag and my old faithful tier one FTR bipod. I am concern the heavy .338 loads are a bit much for the FTR bipod?

I’ve been considering an AccuTac HD50 with an extender and the fortis micro adjustable rear, but have been put off by it being in plastic. Am I being a bit pessimistic, but it seems a lot of money if it’s not going to last. 

I’ve also been looking at an adjustable bag rider, but the adjuster is ‘masked’ by the ears of my bag.

i’ve been agonising over methods of fine adjustment to take my own inabilities out of the equation to achieve accurate long range shots! A small amount of error is a big error at a mile 🤣

Will report back tomorrow evening on how my set up performed after shooting out to 1 Mile+.

Tubb Non-Symmetrical Bipod, AccuTac Extender and Fortis Micro Adjustable Rear Rest.

I use a Tier 1  FTR rest with ski feet on a rubber covered board and a heavy bag (chromate sand).  Shot hundreds of .338 rounds with no issue and decent accuracy maintained.  The rest is still as good as new.  I'm not so much but that's just age....

That's a relief 😃 I made up a board of 1/2" ply to which I bonded a sheet of 1/4" rubber. Works really well with the Creedmoor. I also have a bag, but mine is filled with garnet I scounged from a mate who does media blasting. It's super fine so will find any leak however small, but is very heavy. 

My FTR bipod was an indulgence when it first came out and whilst it was a big financial hit has never disappointed when being used. I have made a bevel drive for it to use when I'm using a bipod extended, but the nylon screws that grip the hand wheel tend to make it fall off with a heavy recoiling rifle. It needs a bit more development but it does make adjusting the bipod much easier, without breaking position.

Set worked better than when I tried with a Tall Rabbit Ears Sand Filled Bag, Fortis Rest was a little more difficult to adjust out in the cold and wind as compared to my test adjustments indoors. Shots were way easier to spot at 1 Mile and the furthest distance of 1809 yards as the gun remained on target after the heavy recoil of a 285 grain bullet moving at 3205 fps.

I was lent a Fortis Rest to try by a friend, but shooting a 1000 yards with both the 6.5 CreedMoor and the .338Lap I found my sand bad was more solid and easier to work with. Very grateful to my friend for lending me one to try - has saved me investing a lot of money 😃

Works for me, 33XC with a lot more recoil that a .338 Lap.

There are lots of options ... Mechanical types which are not allowed within certain competitions and inflatable types which are as of now . It depends upon the shape of your stock or bag rider and how high or low your going to need it to be to get the elevation from your bipod . Trying to get the difference from the rear bag is a lot quicker than keeping altering the bipod and breaking posistion ... Within reason of course . The Fortis wouldn't be for me and my needs but they come with good reviews ?

Here are a few that ive had or made ... ELR inflatable bag from the US which was filled with heavy sand and too big and heavy ... An inflatable rear bag that i made using kids bean bags and a mechanical rest which is my personal choice !

Getting the bag rider to fit the ears is important to me .

What's the name of the Al base in the last 2 pics please?

[OSOK]

I bought the base from Czech from memory but i had to put a piece of ali on the base to stop bounce and i replace the main screw to a course bigger thread . I changed the small bolts on the sides with stainless washer runners etc  . The guy from ' Mark & Sam ' sells them .... I should have bought one of his !

A friend of mine has one. It doesn't seem the Czech fellow understands deburring 🤣 Were I to get one I would factor in a good few hours with a roll of emery cloth 🤣

I really like the idea of an inflatable bag and was considering the Ryan Cheyney I saw in YouTube, though I would like rabbit ears ideally. I have a Protektor Model of a similar ilk to yours, though it has a handle which would mean it wouldn't fit in/on the "Mark & Sam" style device.

Had I not paid so much money for it fairly recently I might be tempted to open it up and install an air bladder.

I saw this DIY bipod extender on a sub12 air rifle so Im sure it will be fine on my 300PRC..  ( total cost £20)

What could possibly go wrong 🤣

 

[martin_b]

I will be using it with a Joypod with Ski feet so that should help with the recoil and I might epoxy the rings, but we'll see as they say.  It does make a hell of a difference on how steady i can hold the cross hair though.

A sense of humour ... Good to see !    ( I hope )  

[martin_b]

Nothing ventured nothing gained,  The carbon fibre tube is 1.5mil thick rather than the usual 1mm. I will move both rings inboard on the tube and shoot it, at least to start with, free recoil and go from there.

[snakeman]

Is this the new 'bouncy-pod'? ..I hope you've submitted this to the patent office, Mart? ... 🤔😃

[martin_b]

The tube is mage of roll wrapped carbon fibre, the stuff they build camera tripods, car chassis, etc out of as opposed to pultruded carbon fiber ( used for fishing rods),  at this dia and load its not going to bend.

Keep us updated Mart 👍
