Hi all. I hope that you are all having a great day. I was testing loads for a trip out west and found that my Encore don't like the first string of shots taken. The first string was a old stand by load( 41gr of Reloader 22 ). This group will shoot around an inch most of the time in both of my 243 rifles. I use it to check that the scope is working and that nothing has changed. That string turned to a 2"group. My first thought was it is me. I was just a little off. The second string was better, same load and this time it was close to the inch I expected. So I went on with the load testing and all was well. I found a load that would give me a half inch four shot group. So I gave up the shooting and went into the house to load up twenty rounds of the new load to see just how good it was. The load is 33.8gr of IMR 4895, CCI primer and 100gr Sierra Game King SP BT. That round runs about 2700 FPS. My thought was it was a good all around light load for paper or game. I also loaded up a hunting load of 43.5gr of IMR 7828 SSC. With 100 gr Sierra Pro-Hunter SP FB. I use the Pro-Hunters in placae of the Nosler Partitions for testing because of the cost. That load gives me over 3000 FPS. I was getting groups around an inch with this load. After loading the shells and doing some other stuff I went to bed and didn't clean the rifle. That is not like me at all, I always clean my rifles after use. I was tired and knew that I was going to use the next day. The next day I shot the first string and got a .75 group then shot the second string that gave me .5 then the third was back to .75 or a little better. I decided to clean the rifle and that is when I knew I had a problem. That string was off the top of the target only one of the shots hit the paper, the last one. The next string gave me a group of about .65 just above the bull. I was now out of the 4895 load and went to the 7828 load. I cleaned the rifle and got the same results, it put the first two shot about 2" high and the third about an inch high and the forth in the bull. Making about a 2.5" group. The next string was back to an inch. In all testing I let the rifle cool down. All shots were taken from a rest. After cleaning the rifle is when I got the bad groups. The last test was I went into the house and got some Wolf ammo that I had and after cleaning the rifle I tried it and got a 6" line down the target that led to the bull. The next string gave me a 2" group that was all around the bull. The rifle don't like a clean barrel. What do I do about the first cold bore shot? I have never not cleaned a rifle and put it away. Do I shoot a four or five shot string before going hunting? Is there a way to fix this? I know this is a long read. I just didn't know how to explain it any other way. Thanks much for any help you can offer.
