200 accubond in 300 wsm range day

[lukeva22]

I went to the range today 04/30/15 with my Tikka t3 lite stainless in 300 wsm. I got some 200 grain AccuBond blems from sps, and wanted to try them out with reloader 19. Sorry for the huge pictures, I don't know how to make them smaller. I didn't take out the chronograph, I might load up some more with 65.7, and see how fast they are going.
The rifle has a bell & carlson medalist stock and a witt machine clamp on muzzle brake.

64.5 middle bullseye
64.8 upper left
65.1 upper right
65.4 lower left
65.7 lower right
66.0 between upper &lower left
one group of 62.5 imr 4350 between upper and lower right (got load from one guy claiming one hole group with his tikka t3 with that load)

best group without flyer (could be me not sure)65.7

65.1 from upper right

64.8 from upper left

Let me know what you guys think.

Nice job! I shoot them in my Kimber 300 WSM using IMR 4350, 62.8 grains gives me 2810 fps. I'm sure other powders would give me more speed but the accuracy is great so why bother.

Thanks, I want to work with it more. I really want to see what it does at longer distances, and also chronograph it. My scope has the rapid z 800 reticle, so I need to put the final muzzle velocity to see how the reticle lines up.

Here is some pics of the gun

Man, I tried to make the 200 AB's shoot in my old 300 WSM and I just couldn't make them consistent. I easily got into the mid 2800's and low 2900's with H4831SC, RL19 and 17 but I just never got the consistency I was looking for.

Great shooting! That's a great load right there.

How does the clamp on muzzle brake work for you? I was considering one for my 300Wby but never could decide which one to get.

I hated testing loads with this gun before I got the brake. I have had no problems with the witt machine brake since I put it on. It makes range sessions enjoyable.
I did use it for the first time this last year while elk hunting, and I didn't even notice how loud it was.

Does the point of impact change when you remove it after a range session? I know you said you used it for your last hunt but wouldn't think about shooting a rifle with out ear protection with a brake on it. My hearing is bad enough as it is thanks to military service and working in heavy industry with high levels of noise.

Sorry I don't know. Once I put it on, I have never taken it off

I just might have to pick one up. I believe the Witt Machine brake is the least expensive of the clamp on brakes.

I think that it was a great investment.

I've been unsuccessful in getting 200 grain AccuBonds shoot well in my 300 WSM (I'm certain the issue could be resolved by playing with seating depth). However, 200 grain Partitions and 200 grain Sierra Game Kings each give me excellent results with good velocities. The same was true in my previous 300 WSM. You have a fine load there in your rifle. You could run with that easily.

Dang it, now I'm going to have to try it. Fine work there, 1/2 minute works anytime.

I seated them out to mag length of 2.88, I measured with an oal gauge, and to reach the lands, would of been 2.976
I am glad they seem to work at mag length.
