ASE Utra moderators

[Bukshot]

HiEveryone, was hoping for some advise on the ASE Utra moderators. I'mconsidering the SL5 for my 6.5x55 which is a factory threaded mauser m03. ASEUtra's website states that the .25 cal size moderator is recommended for the6.5x55 caliber and can be used for bullets up to 6.7mm (not sure why its listedas a .25 cal then as the 6.5x55 is a .264 cal).

Theimporters Jackson rifles tell me that they recommend the ASE Utra .30 cal modfor the 6.5x55. They think the .25 cal moderator tolerances are too tight tosafely use for the 6.5x55 cal. Funnything is Jackson's tested a number of moderators for sporting rifle in 2008(you can google and download the report) where they tested a sauer in 6.5x55with a .25 cal ASE Utra compact, with a good reduction in noise.

Anywayto cut a long story short has anyone used any of ASE Utra's .25 cal moderators ona 6.5x55? Any advise would be appreciated.

Bukshooter,

In the past I've spoken directly with ASE's CEO at a defence show. He uses .30 cal on his Swede. I therefore do the same on mine.

Hi,
I've got a .30 cal ASE Ultra that does my .308 and .243. Sound moderation on the .243 is good, and to be honest I can't tell any difference with my .30 and my mates .25, when on the .243 rifle.

My mate is using a ase utra 25 cal mod on his blaser 6.5x55 for a few years now without any problems.
His rifle came threaded from the factory.
As long as the rifle is threaded properly I cant see any problems.

I've used the .25 moderator o a Sako 6.5x55 for over three years ....no problems. Got confirmation of compatibillity direct from factory

Bucshooter,

What can work and does work is OK then go with it. All I'm saying is that if "at a Defence Show in Paris and in London" the company (and indeed Jackson Rifles) say use a .30 with the Swede ( and their own CEO and other staff choose to do so) then go with what you chose

I have 2 ASE moderators 1 marked .25 and 1 marked .30 the .30 model has .028 inch clearance on a .308 bullet the .25 model sits on the end of my .270 with exactly the same .028 inch clearance on a .277 bullet.
So I would not get too upset with fitting it to a .6.5.

Did you ask him why he did so?

Perhaps it was simply the fact that was what was to hand when he needed one ! Perhaps he also uses it on a .30 cal as well. To me it seems that you have art of the story but not all of it.

I happen to own a .243 Wildcat P8-300 and I use that on a Swede 6.5x55 and a 25-06 and it works fine.

Brithunter,

It was just the way that they grouped calibres. Erring on the side of caution. 6.5 x 55 was in the .30 group.

Stan

 

[Brithunter]

Hmmmm interesting. I can see .270 being grouped in with the .30 as after all we are talking 0.031" but 6.5mm is 0.044" difference and that's over 2mm which is a lot. Would have thought that 6.5mm would be grouped with the 6mm (.243) with only 0.021" difference.

 

[Bukshot]

Thanks guys, thats been helpful information. Picking up an SL5 .30 cal tomorrow to go on my Swede. Decided to err on the side of caution and hopefully it will perform well.

Wish ASE Utra will sort out the grouping mess on there website though. If the .25 cal is good enough for a 6.5mm then why dont they just call it a .64 cal and leave it at that. (Incidently I emailed ASE Utra about this but have'nt had a response yet)

The .25 version is quieter so you might regret getting one with the bigger hole!

Here is a copy of advice I got from Ase Utra lot a couple of years back
"Yes, the .25 calibre jet-Z COMPACT is intended for .243 Win and 6.5x55 calibres for example."
Best Regards!

Thanks Scotspine. The funny thing is when I spoke to Jackson Rifles couple of days ago they explicitly told me they recommend NOT to use the .25 cal for a 6.5x55 (even though ASE Utra say it is OK) because if the muzzle thread is not perfectly cut square (even though its a factory screw cut mauser m03 barrel) or any dirt/hair that gets on the threads could throw alighnment out enough so that the bullet ends up clipping the mod.

All a bit confusing, not sure if Jacksons are giving that advise to cover their own backs? What do you think?

It depends on the bullet weight you intend to shoot from Your 6.5x55. If you are only shooting 100 or 120gr bullets, then as long as your barrel hasnt been threaded by an idiot you should be ok. 130gr and 140gr+ 6.5cal bullets are extremely long for their diameter, and if they come out of the muzzle slightly yawed, then they will clip the baffles due to the minimal clearances.

Well as I said I use a .243 Wildcat P8-300 on mine as as the lead screw nut was worn quite badly on the ole Student I used the old Raglan 5" lathe to turn the muzzle down then used a die to cut the thread on the 6.5mm and thank you it works just fine . If the Student had been fully operational it would have been screw cut but as it was not I used what was to hand. The std bullet I use in the 6.5x55 is the Hornady 139 BTSP.

i have 3 mods all 30 cal used on 22.250,6.5x55,308,i have an ace on my 6.5 dont think its quite so quiet as the t8's but will last longer !

I'm not sure why Jackson Rifles' advice is different from the manufacturer.However a badly cut thread may well cause problems with any mod regardless of specification so the name of the game is get the barrel threaded properly . I went for the smaller hole as it gives best sound reduction.

Doubt it. Jacksons are excellent to deal with whether trade or as a punter and much of their advice is based upon experience.

 

[Bukshot]

Totally agree, Jackson's advice is first rate, didn't mean to doubt them at all. The gentleman I spoke to took the time to explain why they thought that the ASE .30 cal mod is better suited to the 6.5x55 than the .25 cal mod - and he emphasised that was backed up by experience and testing. Being new to moderators (still think they make the rifle look ugly) and wanting to to buy the SL5 I thought I'd see what other SD members experience had been with ASE Utra. Mixed and varied but all good thought provoking advise though.


Thanks everyone

You decide, it is your rifle.
Jackson's will say use the .30 as 6.5-mm is bigger than the .25 cal stamped on the .25 mod.
Personally I would go with a .25 mod for best suppression as I just can't see .0059" making a difference, assuming the barrel thread is true ?
