Trigger Trigger i is identical to o the .22LR m model, so really there is nothing further to mention, howeve er just for interest and confirm m a comment t I made earl lier on in the e article. Sett ting these tri iggers to the eir lowest e is a job for an Armoure er/Gunsmith.

The different is the way the ejector is secured and the fac that its y ct ted. It is a be etter design a and I can only assume height can be adjust a r it was a design improvement incorporated at a later stage in production process. The only minor compla aint is that th he ejector ed by a nut which requires a unique e sized socke et to fit it. is secure The solu ution is to turn down the outside of the socket to o fit. Bedding g Plate This is t first time I have enc the e counter this design. Basically it is steel pla profiled to the sha of the b ate ape barrel where it seats e against the wood. It takes up the play an although primitive nd e rifle barrel tightly again nst the stock. beds the yet its ng I have y to test i effectiveness by firin the rifle with and without the plate an nd recording the results. Barrel The barrels rifling is s very fine, a at first I thou ught the barrel was worn but when I inspected the bore osely I found d the rifling to be almos st new. Therefore I wou uld describe the rifling s similar to more clo micro groove rifling found for a period of time on the American Marlins. Un g nfortunately like the ve rifling was s totally unsuitable for le ead bullets a and thus bec comes a pro oblem for Marlins micro groov who can only y access lead d .22WMR.

ator Modera My final l choice of m moderator w was the steel Asi utra rim mfire modera ator as the ce entre fire moderator was a lit on the l ttle large side an caused lig from the lamp to re nd ght e eflect of its rear panel. A far as As rimfire m moderator's go I have yet to find a more effect tive rimfire m moderator as the Asi Utra and it works ve ery well with h the WMR c cartridge. ne Magazin The mag gazine is obv viously desig gned to acco ommodate th he .22WMR cartridge an nd as a res is naturally larger in size.

Field Tri ials My initia al field trials s included th he torch brac cket, torch and centre fir re moderato or, whilst th he package s shot accurate ely, I had inju ured my arm m at the time and the extra weight c caused me problems, so I removed the bracket a and fitted a t the lighter As se Utra rim mfire moderator for the fi inal field tria als. cutip with 33 3grn jacketed d bullets and d the rifle wa as tested bet tween 25 Ammunition was Remington Acc s. At 25yrds you could ea asily achieve ed a three ro ound group w with all round ds touching however ­ 90yrds the occa asional flyer was not unc common.

The weather was perfec ct with wind speeds of no o more than 35mph. wh hilst there wa as always man t ups I did thin that a mo nk ore consistent brand of .22 Mag the hum element in achieving good grou ammuni ition may be e a solution. Summar ry The rest t of the rifles componen nts are the s same as the .22LR mode els so there is no need t to repeat myself f further. How wever it is fair to say th the .22W hat WMR version has the same very hi build igh quality t that one can expect off these rifles. y ptable but not stunning; I may be a ; able to improve accuracy still furthe with a er Accuracy was accep heavier but slightly slower 40gr bullet.

Serial No 123 3440 Mauser 201 .22LR, S This w was my fourth rifle purch hased in 2010 0 and was pu urchased for tw distinct r wo reasons; the brown rece e eiver and its superb condit tion. To date e this was th he best rifle that I had p procured. It is an n early model as indicated by the se erial number r and the fact th he numbers a d. are engraved Stock The rifle e came with a deluxe sto ock with absolutely no d damage, not even any ca abinet marks s.

However I can refit the e originals at t any time as s they are a s straight swap p. Barrel The barr rel had been n threaded f for a modera ator and if th he rifle had been fitted with a fore sight the evidence e had been l lost. Howeve er there was s a faint mark underneat th the bluing g where the rearsight had bee en. This was an early rifle e therefore any rearsigh ht would hav ve had a welded stud sec curing it. The stud had been removed an the offen d nd nding area p professionally finished. Rifling was in superb y R n conditio on and was id dentical to ot ther barrels from the sam me period. Receiver The rece eiver was identical to ot ther early m model rifles a and was in excellent con e ndition. The principle difference with this receiver w it was brown rather than the traditional blue. I kno from s was e ow nce hen certain steels depending on the s g experien that wh bluing c metals c chemical con ntent they will brown rat ther than blu ue. What I can't id dentify at this stage is whether this w was a manuf facturing accident or a deliberate varia t ation. The underneath of the receiver is blue so t r therefore I f feel this is a deliberate process. a From th authors point of view he w this "brown ning" is cosm metically pleasing g. ceiver also h a protec had ctive sticker as describe in part one of these reports, ed The rear of the rec htly damaged d and had be ecome unsigh htly, therefore I decided to remove it t. however it was sligh Trigger & & Magazine Housing e I have no intention of discussing them any These items are identical to the e other rifles so therefore further.
