Hi Chris, hope you are well, its been a while.
Steer clear of this rifle, its one of the budget throw away jobbies. If you want to build on the cheap, you may find more pleasure in the Howa action (keeping mag lengths in mind).

Yes Ive been well thanks Nathan and a trust you are too, like you ive been flatout working finally got my CF stock sorted after a few more alterations and Sebastian has put an order in for one to go on his 300 which was the push i needed.
I did think the 710 would be junk, a howa is what i want just have to find the right one im looking at a 280.
after a quick hunt yesterday after shooting a 4'' group at 1000 with the practical. i shot at goats 2 one at 780 and one at 650 my position was awkward and missed both 3 times (stupid goats didnt know wat was going on) i then grabbed the 308 i set up for mother bear from same spot and dropped one at 650.
this got me to thinking, most of the terrain i hunt is awkward and maybe less would be better as time too practice with the practical isnt there.
the other option is a brake but im not so fussed on them.
I hate second guessing myself

Re: Remington 710 action
Hi Chris.
I thought I would share this thread, a man of your skills would surely be able to whip up a shielded muzzle brake like Nathan talks about.

Hi Thomas i was playing round with that cocept a couple years ago when we had the engineering shop next door but they move and it faded out. Might have to re look I'll dig out my drawings and pop them up[b]

Re: Remington 710 action
far out that's far more advance then i was thinking Chris.
i was thinking simple kinder like this
if my amazing drawing hasn't cleared that up haha a muzzle break kinder like this with the back threaded and a separate cup or cylinder that screws over it. i can't see how you would machine it in one piece otherwise that would be better. i suggest some grub screws through the thread so it can't unwind otherwise it'll fly backwards towards the shooter if it comes loose.
you could then try it with and without the cup on to

Re: Remington 710 action
After reading some of Nathan and other forum members comments and Nathan's idea of different angles to the vents to help with the noise issues of muzzle brakes
I was wondering if you angled the rear vents forward would the gasses coming out sweep the gasses from the next vents witch in turn may prevent some of that noise coming back just an idea for thought

[quote]far out that's far more advance then i was thinking
Yes I was look at a break that also cut down a little noise but it was going to be too bulky. I'm. Gonna go see the machinist tomorrow see if I can borrow the mill and re visit my ideas the brain is on over time again.

Re: Remington 710 action
I'm sure my brain is constantly in over drive when it comes to this stuff.
I remembered my dad's got my grandfathers home built lathe so I might try get my hands on it next time I go up north.
not sure how true it is but at least it'something.
What would be a good steel to use? As I still got a lot to learn when it comes to steels.

Here's a muzzle brake on trade me that apparently is designed to blow forwards.
Hard to tell from the photo exactly how it works

Stage one complete this cuts recoil down to that of a tikka 243.
Now to play with shrouds

Re: Remington 710 action
looks good Chris
is it sandwinched between muzzle break and barrel or did you thread it?
this is really interesting and looking for forwards to up dates

Re: Remington 710 action
A quick question Chris, cuz I dont know nuthin bout thees things.
Is the volume in the shroud calculated? I know it's the prototype, but I didn't know if it was the final size.

Re: Remington 710 action
Hi Paul no calculations nothing fancy just seeing if I can make a break that keeps noise forward of the muzzle the break inside is pleasant to shoot no percussion wave and no extra noise behind shooter. Now I want to see if I can take the extra noise from the side.

Re: Remington 710 action
it'll be good to experiment and see by changing things what effect they have. it looks like the gap between the brake and the shield is reasonably small so i wonder if this has an effect on recoil.

Re: Remington 710 action
There's about 5mm gap I didn't want to go much bigger as it will get a bit bulky but in saying that I will make a bigger just to see

Re: Remington 710 action
You could also try some forward facing louvered slots on the sides after trying it out as is? Well done Chris the only way to find out eh! awesome project

Re: Remington 710 action
Hi Chris - one method that works in the field is to give the gas a means of rapid expansion. Sort of the venturi effect in reverse. It doesn't have to be huge, but the bigger the better. Just a thought.
And very nice work on the brake, the symmetry is lovely.

Re: Remington 710 action
Here is what might be a better made muzzle brake designed for the Enhanced Ruger Precision rifle. The author of this article tried it on a different rifle and was very pleased with it.

Re: Remington 710 action
Hi Chris, you'll need to try to make sure it retains its symmetry, not affected by bumps etc. Any slightly uneven gas flow will disturb accuracy.
I hope there is enough room for gas flow without putting immense pressure on the stainless tube. May pay to start with a weak load, using 2213sc (guessing its the Practical?) if you have some. Graduate to your regular 2217 full pressure loads bit by bit.
Well done Chris, I hope it pans out.

Re: Remington 710 action
Yes the practical and I've made some light loads with 120 bt s I had lying round. If the idea works the a better design will be made to isolate an movement. As I can't use the machine gear any more I've had to pay someone (he's keen on the idea so made the break cheap) I'm trying to save a buck while testing
