284Win 190Atips - ELR training ticket

[SRGNXL]

Has anyone tested the 190gr Atips from a  284Win? I had a barrel spun up by MIk 1.8Twist 31" for this purpose to get the 190 atips at 2800fts. With a BC of .422 almost as high as the 300GR berger .338 the data looks very intriguing.

According to the ballistic data I had researched, this combo should equal the wind drift specs of my 300NormaMag with 215bergers at 3200fts. Less powder and barrel wear and great training round. 👇

What powder do you use too get 2800fps..

I tried them in my 1 in 9 7mm 270 a couple of years ago..

Had them shooting bugholes at 100yds doing 3000fps but at 1000yds they were shotgunning..

Twist wasn't fast enough too stabilise them..

I found that out in a big comp..

Switched back too the 180gr hybrids and it shot great again..

My 1 in 8.25 saum shoots the 190gr Atips nice aswell..

57.5gr N165 in a 1.8twist. I will next put this round head to head with a 300NM at 1000yards to see wind drift patterns on paper when both rifles are shot simultaneously head to head at the same time with same dope on the windage.

Would be nice too see the results 👍

I tested the new batch of N165 yesterday..

I've already found out the velocities were down so I went up 1gr and gave them a whirl..

The 195s shot around 0.5 inches and need a bit more work..

The 190gr Atips shot well but I think the stray shot was me...

Seem to be finding my eyes are straining and blurring a bit and I have too wait for it too clear..

There was a little heat haze I think..

Photo is 5 shot group at 100yds with 190gr.

4 in the 1 hole then a deserter.

Not too bad considering the barrel has done 2260 shots

Average over 4 shots was 2838fps with an ES of 15fps.

60.5grs of N165

Retested the 190gr Atip load I tried last weekend and they repeated nicely today..!!

I tried upping the load by 0.2grs and the bolt had a very slight resistance and the group was horizontal so  I'll stick with the first load.

Again 5 shot group at 100yds

Looking good for this year then mate

It may be short lived accuracy as the barrel has done nearing 2300 shots.

I'll likely shoot it until it dies but not in a big match. 

It's always shot the Atips like this until I started on a new powder..

I didn't try it for accuracy with the new batch of powder only chronied it..

It was that much slower I thought it best too get speed up too where it did like it..

Still likes it at that velocity..!!
