Hi all,
Quick write-up to kill an afternoon in lockdown.
Heard a lot about copper bullets not being great, bullets are fine you just need to understand them.
Had experience of using Sako Powerhead 2 ammunition for the .270 Winchester chambering in various rifles. My aim was to improve on this loading.
The bullet itself (Barnes TTSX 110 grain .277) is good, but I figured the loading was coming out a bit slow from a 20 inch barrel.
The bullets seated much deeper than what Barnes recommend (following Barnes data, you can see the last drive band over the case neck, Sako have seated past that so only the last groove is visible) and there was still quite a lot of case capacity left judging by the amount of noise made by the powder in the case. Not very scientific but I couldn't be bothered pulling a bullet and weighing the powder charge (impossible to tell what powder they are using anyway).
So, I looked through the useful info on here and got in touch with @takbok had done some tests with Viht N160 and Barnes TTSX 110 grain bullets. Since that powder is not too hard to come by I bought a tub and gave it a try.
That is 5 rounds fired sequentially at 100 meters out of a Tikka T3x with a 20 inch barrel and ASE moderator.
Component breakdown:
Powder Viht N160, 63 grains (measured by volume not weight)
Primer Federal Large Rifle Match
Case Winchester (W.W Super headstamp) am phasing these out on their 4th firing, have switched to Norma brass
Neck sized and crimped.
Not bad.
They work well on both Roe and Red deer in stalking done before lockdown.
