RF Shooting

This past weekend I finally got a chance to do some rimfire shooting - I almost forgot the basics😋. As I did not have much time I only took one rifle to the range with the plan to re-tune the barrel tuner after I had made some adjustments during the lockdown period. I took the Red Devil - Anschutz '54 with Krieger barrel.

I have had some trouble with this gun as it shoots on the spot and then suddenly the shot drops 4 rings. The same setup is used for the HV and Sporter guns so I don't think it is a setup problem.

The changes to the Krokodilspruit range did not have much effect on the shooting, but I think it was mainly because I was at the range early and got my shooting done before the usual winds got going.

I setup to the right of the range (bench 23) and mostly shot the green-(ish) condition. The wind was not that strong blowing the light tails between 7 and 8 o'clock. As per usual I start at diagram 25 and work it back.

I started off with Lapua Centre-X ammo. I noticed that the slower batches started shooting better, I started with batch number that started with 295, 275 and then 265, for some reason I did not pack the 255 batch.

The way I test - I shoot 5 shot groups at a diagram without compensating for wind conditions. I shoot different batches and manufacturers before adjusting the barrel tuner - don't judge, I have not shot rimfire in a long while and getting my seating correct takes some time. See the table below for info what diagram was shot with which ammo. Note - diagram 5 I did not notice my 1st flag picking up the tail from 6 to 8 o'clock.

I have ordered a new barrel tuner for this gun as I have fiddled with the tuner on the lathe some time ago, will need to follow up in the coming week when I can expect delivery.

I will need to take out this gun for another test session to see if this tune will stick and if not I will replace the tuner and start again. Another change I will consider is to fit it to on of my backup Renier Mostert Rimfire Stocks, and see if that makes a difference.
