I went down to the range today, loaded up my quad and all of my shooting gear, to include the chrono. I had my wifes 308, my 338WM and my 22-250.
I wanted to finish shooting my last AA2520 loads with the 60gr PT. They came out the shoot really fast 34gr's (3470 AVG), and look very consistent as far as speed, but they didn't really group so hot.
(target is mislabled)
The 33gr load was bigger yet. Might have been able to mess with it some, but I have a have a good load with Varget at 3350. Just didn't want to leave any stone unturned.
Now, for my wifes 308. I was using 180gr BT's and IMR4064, Varget, RL15 and W748. Both Varget and IMR4064 groups were in the two inch range, and some were a little larger. W748 was the winner of the day with this group.
Velocity was right at 2650 for those loads and the cases look very good. I loaded a bunch for that gun today, and it seems to have some promise with W748. Speed seems right on for me. Varget picked up second place, but the speed was about 50FPS slower. No big deal, but I was getting nice triangles with the 748. So I think I have something more to work with in the future.
Next up was my 22-250 with 50gr BT's. I loaded Varget according to the Hogdon Max of 37.5 and I started with 35.5. Ended up shooting three rounds within about a .5 inch at 36.5 for about 3750FPS. Not scorching, but it seems very accurate. I want to mess with OAL a little, but that kind of accuracy is great for predators, and just messing around with varmints and such.
I shot the 338WM with some more 275gr Speers, I wanted to see how they held up over range. My load is 275gr Speer, 72gr of RL22, CCI250 and a COAL 3.34. First group to confirm my zero at 100 had two shots touching, about 2" high. After that I went to 200. I shot this target at 200. I was really elated to see that. I shot one more after this, and it is was a touch bigger, but still a neat group under 1.25".
After that, I decided to see if the B&C reticle matched up at 300 yards. It is the 2nd tick down. Here is what I shot. I kinda blew it out my but. I could have done better, but I didn't let my barrel cool enough, and was kind of rushing since I was on a little high after the 200 yard groups.
I made a one click left adjustment and plugged three shots into the bull! I lost that target on the back of my quad on the way back to my buddies house, but it was pretty good for initial shooting. I am very happy with the B&C reticle working well with the 338 loads. I can shoot to 400, just gotta get some more time.
We did finish load work for my buddy AR-15. It is an M&P15 S&W (16" barrel). It has a 1-9 twist barrel. I loaded Benchmark for him under the 60gr Partition. We started at 22.5 and stopped at 25gr of Benchmark. It shot its last group into an inch for about 2900FPS. It had a spread of about 20FPS for 5 shots. Not great, but seems pretty good for a gas gun. Anyhow, that was my day at the range.
Here is the target from the first round with the 22-250. I used RL15 and Varget. Seems like 33gr of Varget really wants to shoot, and they were clocking 3350, so I am going to load some more up and shoot them a little further out and see what they do. Scotty
