.25x700 liner in my Impact MK2, no aftermarket anything barrel stiffeners or whatever else called money grab. I am shooting BR 100 meters and the MK2 is capable of sub moa if I do my part.

LW barrel for impact.

Another thing to consider is how good is the barrel you just chucked up in your lathe. Over the last four or five years I’ve done 5 TJ barrels in .25. They are not the same. If I build another one for my Impact it might shoot better than this one. That’s a lot of work just to fire slow projectiles at close distance at nothing important. On the flip side, and I promise you I’m not a FX fanboy, you can test 3 liners and never even bust out a pair of calipers. The whole FX thing just involves a ton of lead. Yes you can get lucky with the first thing you try but even that won’t last long because you will read something that will have you sniffing another slug, reg setting, speed, liner or bolt on gadget. You just have to face the fact that you are going to do a lot of shooting trying to find something you can trust every time you take the gun out of the safe. You might never do it depending on your standards.

Well yes with a 700mm it would be extremely front heavy. But then again depends on what you are doing. On my bench impact I use the 700mm and the 800mm, still put a additional 8 lb steel weight when it is on the bench. Now playing with the alteros slugs, the 800 fires them a little too fast. But many of the others like the faster speeds that my stock configured mk2 does not do as well in 700mm

I might give the rifle Abit more time to break in good I haven't even tried anything over 34 gn and still under a 1000 shots on it. And it's shooting the knockouts well,I've got some griffin slugs otw and gonna try some NSA and Zan's. Your right on in the last part of thread.

I have a impact 25 cal and it doesn’t need a lw barrel. I’ve also had 2 lw barrels in 177 made for the maverick I had and they shot no better than the fx barrel so the 2 mavericks I had went bye bye

LW tends to like lighter projectiles at lower speeds. The hexogonal ones are REAl finnicky. Once you find what they like , they can shoot real well, but I'd bet $$$ I could get an fx liner to do better.

Had a custom 500mm TJ barrel on my Impact and holy cow it added significant weight, it didn't shoot any better and super ammo picky. Can't imagine a 700mm solid barrel on that gun, ok for bench I guess. I've shot heavy slugs out of the heavy liner with great success, tuning is the key.

Since I'm using it for hunting, sure don't want to add anymore weight, from all the replies it seems like a heavy liner makes the most sense to try first. Thanks for the info.

If you shoot pellet then heavy liner is a waste of time and money. If you shoot slugs 29 grains or less then also waste of time and money. Only time you need heavy liners is when you need to shoot heavier 34 grain or heavier slugs because of the twist rate. For anything under 100 yards heavier slugs are really not needed or waste of money and time, the 29 grain slugs @900fps pack a whole can of whoopass even for medium size games. Only upgrade I highly recommend to get regardless is the carbon liner sleeve, it just replaces the stupid orings I hate so much.
The stock impact does just fine WITHOUT ANY upgrades! If you really are paranoid about POI shift then get the carbon liner sleeve and tensioning kit, nothing else is needed. I took the tensioning kit off because it's easier to tune without it, the nodes are bigger and easier to find without tensioner. I've hunted with impact without the tensioning kit and did NOT have any issues even after bumping, dropping it and rolled over it with my 200lb body weight after tripping on a rock. YMMV.

I'm currently shooting 34 gn knockouts 950s an getting good groups with the standard liner. 1/2 moa at 80 yds. That's satisfactory for hunting. But Im probably maxed out on the slug weight for that liner.

And still using the pellet probe. With the accuracy I'm getting I haven't seen the need to change it. But if I go heavy weight ,I will probably need too unless my groups stay tight.

We been putting the LW barrels on the Impact years ago.
I milled the LW on my MK2 with great results few years back. Actually, they seem to do better than the FX heavy superior barrels.
At that time the blanks were around 120+/- $$ if you bought so many.
We ended up getting 2@ .22cal and 2@ .25cal to try out.
The only reason I'd went back to the FX barrels was because without the factory shroud, it was about 20-25% louder, even with a moderator on it.
It's great for bench shooting long distance 150-300 yards but not practical for hunting for game.
It's funny that I'd seen this post, I'm actually selling the LW to someone online.
FYI, pics are below.
