Poor quality A/P practise and some new pellets

On a slightly cold range, a rushed 70-shot practise session at 10M air pistol. After the initial 10-shot warm up, ended up with the following stats for the session:

STATS
-----

Session total: 432 ex 600
Session Average: 72.0

Running Average: 79.2
Running Std. Dev: 6.83
BC: 1460

Did make some changes during the session: moved rearsight elevation 20 clicks H to lower the grouping;  moved rearsight5 clicks R to shift the group to the left slightly.

Also shot several of the cards with RWS R10 Match 4.49mm ammunition. This is only £8/500 compared to H&N Finale Match 4.49mm ammunition at £11/500. The
RWS R10 Match pellets have a slightly thicker skirt than the H&N, and are a little easier to seating when loading.

R8 = BAD

Very poor round 8 shot on a very busy, noisy and congested range. Managed only a 66.0 to increase the standard deviation to a truly massive 9.36.

The running average for the Kent competition is now a disappointing 77.3 with an std.dev of 5.43

Overall I am now running an overall 79.24 black powder average. 

Getting ahead with the Kent Black Powder Leagues

On a slightly warmer range than recent weekends, managed to shoot rounds 6 and 7 of the summer season league. Using the normal setup:

Pistol: .36 Mortimer
Powder: 10.1gns of Swiss No.1
Patches: 0.015"  Ox-Yoke prelubed
Balls: .350" Hornady
Filler: 6.5gns of coarse ground semolina

shot the first of the two cards, round 6, for an 81.0

This set the Std.Dev to date to 1.12 indicating a card shot very close to current average. Without a break, shot the second card, round 7, for an 80.0

Although there is a pair of keyholed shots in the 9-ring at 1 o'clock, the card suffered several flyers due to lack of concentration following an incident on the range mid way through the card. Whilst cleaning the barrel after shot number 7, the jag holding the cleaning swab, snapped off at the bottom of the barrel:

I was unable to extract it from the muzzle end, so had to try another [successful] method; remove the access screw from the percussion nipple housing, carefully drop in 3-4 grains of black powder, reinsert the access screw, cap the nipple and then fire carefully downrange. Thankfully the small 'explosion' ejected the remains of the jag and swab.

I then went on to complete the card!
