Whitey now has a few nice , plump pigeon breasts to eat. The Cheapo Chink, once again proved itself to be a handy little workhorse. Closest taken from the top of a dead Oak tree at 40 yards. The next two at 57 and 62 - witnessed by my mate. I,m almost tempted to take the barrel off and fit it to the new rifle. But that would ruin a cracking little combo. Anyway, this morning I removed the choke from the Weihrauch barrel. That allowed me to add another two baffles in the front end of the shroud. And the signs are promising. Accuracy doesn,t seem too bad and it is definitely quieter. Interestingly, the power rose from 10.5 to 11.7 fpe. Shows how tight the choke was.

How can you tell that a choke is too tight?

With a shotgun I think it's pretty obvious if the spread of the shot is too small but how do you tell with an airgun?

By slowly pushing a pellet up the barrel, from the breech end and then suddenly you will feel a little more resistance , usually 30 -40 mm from the muzzle.

If you read my last post Rab you,ll see I removed the choke. What I need to do now is test the rifle with as many pellets as I can to see if it groups at longer ranges. My pal who uses among other rifles, an fac Rapid, says a guy on the Rapid Forum quite often removes chokes to cure inaccuracy problems.

I thought the choke was to IMPROVE accuracy.

I thought the idea is that is "pinches" the pellet into a straight/consistent trajectory as it leaves the barrel.

depends on the quality of the barrel as well as the power of the gun, the pellet used, the distance shooting over and a million other things.

It takes a brave man to remove a choke from a rifled barrel....but I suppose if the barrel is giving poor accuracy anyway, then you have nothing to lose if it doesn't work.

The barrel was given to me by Dave Welham . He said a friend choked it for him but overdid it slightly. So,  removing the choke wasn,t going to loose me money. Anyway, I took it show a mate last night and we tested it at 35 yards. From a rested but not very comfortable position it produced three 10mm groups. Happy with that. I reckon that with a leaded up barrel and shooting from a bi-pod I should get better groups. I will test it next week at 45 yards. Then, if the accuracy is good enough, it will get blooded on bunnies.

I,ve been a bit fed up this week, the old black dog again. I,ve been wanting to test the rifle at longer ranges but couldn,t be arsed. It does that to you sometimes. Anyway, I finally took it into the woods the other day as there was almost no wind blowing. Shooting from a very uncomfortable position and using my favourite pellets - H&N Sniper Mediums , I managed a nice , tight group at 45 yards. Five shots went through the same , small hole measuring around 12mm. Happy with that.
