A few weeks ago I was contacted by Simon Lawrence of Lawrence Precision and was invited to witness a sound test and review of moderators, including the new 'Zodiac' model at the Corinium Rifle Range near Cirencester. The comparison was to be conducted by Paul Hill, the owner of the range, and was intended to compare some of the more popular moderators on the market against the recently revised range of Lawrence Precision Titanium products, taking into account sound attenuation and weight.
As some of you are no doubt aware, I have used a LP moderator on my .30-06 for the last two years and have been very pleased with it so I suppose the results didn't come as too much of a surprise to me however here is a summary of what we found!
On test were (all .30 cal):
- Ase utra Northstar Stainless Steel
- ASE utra Jet Z Carbon Steel
- Latest uprated Lawrence Precision Nexus Titanium
- Latest uprated Lawrence precision Eclipse Titanium
- Brand New model Lawrence Precision Zodiac Titanium
Weight , lightest first
- Nexus 390 grams
- Eclipse 420 grams
- Zodiac 460 grams
- Ase Jet Z 570 grams
- Ase North star 700 grams
Noise attenuation quietest first
- ZODIAC, strikingly so!
- Ase jet Z ( published 28-32 dba reduction) New Nexus (Similar)
- Ase Northstar ( published 25-26 dba)
Size largest first
- Northstar , Eclipse Zodiac ( all similar)
- Nexus Ase Jet Z ( similar in diameter, nexus 65mm longer )
While the steel versions perform well and have their place in the market, all the tested Lawrence precision moderators were lighter, smaller and quieter in general than the other brands on test, the new Zodiac standing out as being exceptional.
As has already been discussed at length on here, Titanium does come at a cost, however if you can see past just cost you can reap the benefits of weight saving, an almost indefinite service life and pretty much zero maintenance.

I'd also like to add that if anyone in the Cirencester area needs access to a tidy 100 yard range then they could do a lot worse than contacting Paul (HME) on here. He has a good set up ideally suited for the stalker/load developer and is a thoroughly helpful and knowledgeable chap, even if he is a Blaser fanboy!
