A letter from the Thames Valley Police dropped onto my door mat this week. Before tearing it open open, the fear of a speeding fine filled my mind, had I been caught by a hidden speed trap? No, it was a reminder that my Firearms Certificate was due to run out in six months and that I needed to renew it as soon as possible, to avoid not being covered. When I last renewed, the whole process, including a visit from the local Firearms Officer, had taken under six weeks. Now due to the “current peak renewal period” it was now six months minimum.

Terrorism raises it’s head in all walks of life today and no less with legally held firearms, various government departments processing information back and forth, with more detailed intelligence checks needed by the Information Research Bureau, including contact with an applicant’s GP and deeper checks on referees. My information is the same as my last two applications and hope for a clean run through. I will be putting in a variation on the new .17 WSM (Winchester Super Magnum) bolt action rimfire. Maybe that will slow it down.

One of the requirements, when applying, is that the current certificate has to be sent along with the application form. What’s the problem you say, well without the actual certificate, ammunition cannot be purchased, as all bullets bought have to be written by hand on the back of the certificate, along with the signature and number of the Registered Firearms Dealer at the time of purchase. This means that my stock of ammunition needs to last at least six months, until I receive my new certificate.

HMR ammunition has been unavailable at my RFD for months with promises of a new batch in the country “any day now” for at least a month. Only able to purchase 200 at a time, I’m already well into the last 100, so do I hang on for a few weeks in the hope of a delivery, or end up running out once the warm weather arrives? With two new permissions to explore this is a possibility.

.22 subsonsonic ammunition is readily available, but my semi automatic Magtech will only recycle certain brands. Eley subs were the best through this rifle, then they became unavailable in my area. I tried 40 grain Winchester, but these jammed on every other round. Recommended German made RWS, I tried them and they worked well, being accurate and quiet. Having bought 500, I was now down to the last 200 and in need of a top up, but guess what? The RFD has stopped stocking them too.

Winchester have recently brought out a 42 grain bullet with slightly more power than the RWS, which is supposed to give better recycling in a semi auto, being heavier with a speed difference of 1065 FPS to the slower 990 FPS of the RWS. I bought a box of 50 and set off to my nearest permission to give them a comparison field test.

It was a cold, damp, but still afternoon and I set up two targets side by at fifty yards, checking the zero on another target using the RWS. The zero had not moved and single shots gave hits in and around the 10 mm bull. Ideal for rabbit head shots. Of these ten shots, one did not recycle. Firing ten of the Winchester, there were no misfires and similar accuracy, although the report through the silencer was deeper in tone, but not loud. Happy so far.

Moving on to the test targets, I fired five RWS  shots in five seconds, a good test of the semi auto Magtech. The first shot went straight through the bull, two edged the 10 mm bull and the other two hit the main target area with a maximum deviation to the left of 20 mm centres, these two being the last fired. Maybe warming of the barrel, or pilot error, but pretty good for rapid fire and a certain kill on any rabbit.

Next up was the Winchester 42 grain, again similar results, one in the bull, two others edging and two out to the left, the furthest at 22 mm centres, but an almost identical pattern as the RWS. Most of the RWS were just below the centre of the bull, while the Winchesters were above, possibly due to the extra speed and power of the bullet giving less drop despite the additional weight.

This test was enough to give me the confidence to buy another 300 Winchesters  and with .22 High Velocity Remingtons already in the ammo box, the top up brings me near my 650 limit for .22 rimfire.

Hoping to try out the Winchesters on a rabbit, I went for a walk along the hedgerows, but nothing was on show and with the light drizzle turning to sleet, I headed back to the van.

A post script to this blog was a phone call saying that my 17 Hornady were now in stock, so it was a quick drive to the RFD to use the FAC to buy enough ammunition to see me through the application period. The assistant in the sports shop said that I would be lucky to get the new certificate in six months, as he has been waiting for nine!
