In recent weeks the long awaited 1st shipment of the howa M1100 22lr rifles arrived in australia.
The following is an amateur review of the rifle.
The main criteria for ordering this rifle type was the expectation that apart from hunting applications, it would also provide value for money for anyone wishing to use it for general club competitions’. Ie field rifle, metallic silhouette and benchrest etc.
Naturally to satisfy these requirements, reliable and consistent accuracy standards needed to be met.
Hopefully it would be able to achieve groups of ½ inch or less at 50 metres or around 1 inch groups at 100 metres. If these standards were met it was also intended to use the Howa M1100 for practicing LRBR by shooting it at 300m.
I was also under the impression that according to howa Japan, that it had a semi match bentz chamber and according to previous media releases that it was supplied with polygonal barrel rifling and would accept the installation of the various match triggers available for howa centrefire rifles. (more on these expectations later !!)
Ok, enough of the preamble and onto the information that may interest others.
Upon opening the box, it is interesting that the packaging reveals a separate barrelled action and stock with 2 magazines and a set of 1 inch integral mounts which only takes a few minutes to assemble.
Next step was to remove the storage residue from the barrel and inspect the bore and chamber with a borescope.
Surprise surprise, no polygonal rifling, just land and groove???
Inserting an SK match round into the chamber, revealed on removal, no evidence of land marks which disappointingly, tends to question the claim by howa that it has a semi match chamber????
However it was not all bad news, the borescope did highlight the chamber and throat being cleanly cut and the barrel appearing to have above average land and groove definitions with no chatter or noticeable imperfections, but as most know the all this means nothing, unless the required consistent accuracy standards are achieved.
As can be seen the action beds on the rear tang and the 2 sections where the action screws pass through the stock. As assembled it was pleasing to see that the barrel is centred and has ample free floating clearance.
The bolt has one locking lug and fits very precisely in the action and cycles very smoothly without any chatter or roughness from machining marks, as would be expected with Japanese quality control.
Whilst the trigger unit initially appears identical to the centrefire version, rather than have the steel body of the centrefire version, the M1100 trigger is apparently an alloy casing or body with similar adjustments and release poundage to the centrefire model.
The replacement Howa centrefire triggers such as the rifle basix etc attach easily to the rimfire action but unfortunately they do not allow the bolt to close in the action notch. Additionally the safety levers on the replacement triggers also prevent the bolt from closing.
As it was intended to set this rifle up for LRBR practice applications, previous experiences with a 22lr at 300m indicated that the combined bases, scope mounts and scope internals needed to be able to provide around 50 to 60 minutes of elevation.
A Remington 581 20 moa base fitted perfectly after the centre section was removed. Burris signature ring with 20moa adjustment and a tasco 20x sniper scope with + or – 50 minutes of internal adjustments satisfied the required optical and elevation requirements.
Now the big question? How would it shoot?
So far only SK Long Range ammunition has been tested and so far the Howa 1100 has surprisingly and pleasingly met our required standards.
Groups at 50metres in good conditions range from 3/8 inch to just over ½ inch.
Best group at 100 metres is 5/8 of an inch with others in the 3/4 inch to 1.25 inch range.
Only one group has been shot at 300m and no doubt luck was a major factor, but 7 shots into approximately 6 inches in real world conditions was very pleasing but unexpected.
time will tell if other brands or batches of ammunition produce better, worse or similar results, but it will all be a fun time finding out.
It would be interesting to obtain feedback from others who purchase the M1100 and compare their findings and accuracy obtainments.
