Re: More Berger 300 Hybrid Gen 2 testing
Sorry for the late response. I've been working with these bullets since my last post and finally have some "long" range results.
Since my last post I played around with different charge weights and seating depths and have come to the conclusion that even though I don't get my best accuracy at 100 yards with this load, it is the best for long distance shooting.
The load is 92 gr of H1000 with the 300 gr Berger. Ironically this is the same load as I use with the Sierra's. As for seating depth, I found that I get better results with the bullet touching the lands. Although I did run a quick test with 3 rounds to see what would happen if I seated the bullet so I could get the cartridge to fit into the magazine. These particular rounds functioned fine, with no signs of pressure and the accuracy at 100 was about the same as the load with the bullet touching the lands. I'll probably play around with this more in the future.
"Real World Results" were excellent. A week ago I decided to test the 92 gr load again at 300 yards. This load gives me around 2860 fps from a 30" barrel. The results I got were a 1/2moa group with three rounds. Seeing this, I then decided to use the last 2 rounds on a 700 yard gong, just to see what they would do and to see if my program on my PDA was on. As it turned out I used what the PDA told me and both rounds hit in the center of the 700 yard gong. I didn't take a measurement, but it was very impressive group for that far away.
Then on Friday, the day after Thanksgiving, my club had a 1 mile shoot. I decided to go with the 92 gr load using the 300 gr Bergers, instead of my usual Sierra load. This proved to be a good choice!
The way the shoot works is we usually start at around 1200 yards, take 5 shots, and then work our way back to 1500, then 1760, then 2000 yards. The targets are 4' x 4' square and 2' x 2' square AR500 steel.
The wind was terrible that day. It was averaging 10 - 12 mph with 20 mph gusts and was bitter cold. We decided to start out at 1400 yards, because of the bad conditions and the fact that most of us hit with every shot at 1200 yards at the last shoot. The wind coming at us from the 1 to 2 o'clock position. The terrain was fairly flat until around the 1000 yard mark where the bullet would then fly across a small gully maybe 10 or 20 feet deep, then the terrain went uphill sharply to the target. This made reading the wind very tricky. At the target itself, you could see the wind coming down the hill, which equated to a 1 moa up correction at 1400 yards and almost 2 moa up correction at 1760 yards. The wind in the gully area was swirling and wreaked havoc on those who weren't paying attention to it. The wind was a major factor and took some of our top shooters from the last 1 mile shoot out of the top spots at this event.
My partner was excellent in calling the corrections to me. In fact, once I hit on the second try, he was yelling at me to get the rest off quickly so that I didn't even have time to see where my hits were going. At the 1400 yard mark I barely missed to the right of the 4' x 4' target, but with the corrections hit on the next 4. We decided that we'd try the 2' x 2' target and both of us hit on our 2nd try. No one else in the group tried to hit this target.
At 1760 (1 mile) the same thing. I missed the first two, but on the last three shots, I hit all of them, but did not see where they went because of my spotter was pushing me to get them off fast again.
After I was done, one of the guys came up to me and told me that I had a very nice group on the target. This was very good to hear, as I had no idea where any of them landed.
Another thing I noticed was even though I needed to correct my elevation up for the down winds we were experiencing, my elevation was around 4 MOA lower than the same dope I use for the 300 gr. Sierra's.
Needless to say, I'm really liking these new Berger bullets. Going into this shoot somewhat blind, because I hadn't even practiced with this load at these distances, had me a bit concerned, but I actually managed to pull out a win. (I didn't really win anything except bragging rights until the next shoot ;-) ) But I'm very please with how these bullet performed in that wind. I can't wait to try them out on a calm day and not have my partner yelling at me to get them off fast. :-)
