Deer legal N555 loads for .243
Posted: Sun Apr 24, 2022 12:27 pm
Greetings any deer stalkers
I'm sure that some stalkers like me who prefer to stalk Muntjac with .243 will have encountered the challenge of achieving 1700 ft lbs with a 100 grain bullet without incurring high pressure issues. I experienced that several years ago when I was starting out with .243 (having only ever shot deer with .308 prior to that) and eventually I gave up trying and since then have used 90 grain to good effect, loading with N160.
Over the last couple of years of course ammunition components have at times been hard to find, and my preferred 90gn small deer bullet, the Nosler Ballistic Tip, has disappeared off the face of the earth. Or might as well have. I have worked up accurate loads with 85gn alternatives (Sierra Varminter and Speer BT) but the more accurate (for me) Varminter is a pain to seat as it has a flat base, so on a recent visit to Spud in Aylsham I was tempted to purchase some 95gn Noslers and am now about to put some test loads together for a trip to Bisley next weekend.
As luck would have it, on paper - and loading with N160 - the 95gn heads appear to present at least a similar problem as the 100gn, albeit maybe less of a challenge. So I was intrigued to see that Vihtavuori has started including N555 in their .243 reloading data against some but not all heads, among them 95gn. I can't (and wouldn't) make any assumptions about that data, not least because they use a 23" barrel in their tests while mine is 20". But Quickload is pointing me to a deer legal energy load using N555
and so I will put a few rounds together to see how they perform.
So that's the back story and where I've got to. Does the story ring bells with any of you? If you've been experimenting with N555 in .243, may I ask how have you got on?
