I have recently had a custom rifle built by a UK based gunsmith called UKgunworks!! It's based on a Tikka T3 action , it has a McMillan Sako varmint stock / UK gunworks action screws and tactical bolt handle and knob / Krieger 24 inch fluted tube chambered for 6•5-55 improved and a 290 neck. I am using a Ase ultra S5 sound moderator too!! The load I am using is .. Norma brass Federal 210 M Viht N160 123 A-max This load is shooting very well and going along at 3000fps. My quest with this rifle is to get a 1000yd shot on a bunnie!! I have had some near hits between 830- 1078yds ,on the last 3 outings i have been missing by inches not feet!! The other night after setting up at one of my favourite vantage points I spotted a bunnie!! It was a good safe shot and ranged at 697yds!! So I dialed in the elevation and windage settings and squeezed of the shot!! The beauty with the moderator is that after the shot the rifle came back on target and I seen the vapour trail going in and the bunnie roll over , I then heard the sound of ( thump!! ) of the report!! It's early days but I am sure impressed with the rifle / caliber and load choice!! All the best from over the pond , Ray.
