6X284 Load Developement w/87grn V-MAX (Wow!!!!)
Hello all, as some of you may know, I received my 6x284 last week. So, today was the big day for barrel brake in and possible load developement.
The morning started out at 0500, took a shower, started the coffee, packed some lunch and drinks, packed the Ford F250, and away I went. Weather was perfect. I started the morning off with the break in on the 30", 1-12 twist Krieger. It only took about 20 rounds to brake her in. Of course this took some time. I fired 8 shots and cleaned after every shot. I then cleaned every 2 shots, for three times. Finished up barrel break in firing two, three shots goups. Barrel break in was very quick with the Krieger, breakin was probably finshed after the 10 shot, however, I went through the whole deal just to be sure.
Now, on with the load developement. As many of you know I have posted many times asking questions about load data using the 87grn and 75grn V-Max. I had this rifle built to shoot the lighter bullets, that's why I went with the 1-12 twist barrel. I also wanted to shoot these bullets at a very high velocity, I was hoping to get close to 3800 fps with the 87grn V-max with excellent accuracy. Well, all I can say is that I am one HAPPY DUDE.
After barrel break in, I fired my first three shot group at 100 yards, the group was AWESOME!!! it measured .218. and the velocity was around 3670 to 3690fps. The load consisted of;
1. 52.5grns H4350
2. Fed210M Primer
3. 87grn V-Max
I did not think it could get better then that, but it did! My next three shot group was AWESOME, AWSOME, AWESOME!!!!! it measured .168, and my next three shot group measured .190, and here is the best thing, the velocities were between 3730 and 3750fps!!! There were no presure signs with this load, so that makes it even better. I wanted to get 3800fps, but hey, that's close enough. I had some hotter loads to test, however, I was really happy with this load, I am going to stick with it and make it my dedicated load in this rifle. Here are the contents of the Winning load;
1. 53.2grn H4350
2. 87grn V-Max, .005 off lands
3. 210M Primeer
4. Lupa Brass
5. C.O.L 2.865
6. Velcocity between 3730 to 3750 fps
7. Shoots in the high .1's out my rifle
7. Brass was neck turned, flash holes cleaned, uniformed primer pockets, trimmed, checked for runout, ect.
I was very impressed with the 87grn V-Max. I know it's not the BC King, but for the blow up power it provides, it's one hell of an all around bullet. With a BC of .400, I should be in good shape out to 800 to 1000 yards. I am very excited, this is going to be one hell of a varmint rig. All 6MM's seem to be the perfect varmint rifles, no matter which one you choice. Anyhow, I am very excited about this rifle, I can't wait to take it varmint hunting next year.
