Rifle ammo or calibre??

[BenBhoy 4,706]

Having some issues with my hmr. Browning t bolt. It's accurate enough, hitting targets at several distances. But too often now when I hit something (nothing over 110yds) I'm getting feathers come off but the crow flies off. This never used to be an issue. Still using vmax 17gn I've always used. This is main reason I'm considering swapping for a hornet.

Any thoughts or suggestions on different hmr ammo? Cheers

Just not hit square enough I would say

Have you got wind, no not you, I mean is it windy?

Or is it the notorious heavy trigger on them there Brownings.

Have you re checked the zero?

Group size?

Is it a new or different batch of ammo?

I shot a 2" metal gong just now and hit it 5 times.

100yds

It's good that you are hitting a 2" target at 100 Ben but we're they in the center or spread all over it or were they just on one edge?

When was the barrel de- coppered?

In all honesty the gong is so pock marked I can't tell! Just see & hear each hit. 

Erm........ de coppered..... my cleaning regime isn't great!! No, not since I've owned it (got it 2nd hand) 

[BenBhoy 4,706]

I'll set paper target & do a decent group test.

Hmr operate at a velocity where copper deposits build up. Just the same as most center fires.

After a while they need a good copper solvent.

The thing with hmr ballistic tips is inconsistent fragmentation. It depends what they strike in the body of a small animal or bird, that determines the terminal effect. If they only contact soft tissue, not a vital organ, they can pass through with very little expansion, therefore not always an instant kill. But then, I might be talking crap, it has been known
