Old Fart, I am partial to Hornady plastic tipped bullets and would recommend the 165 or 180gr SST. I use the 165gr SST w/ moly over H4350 and CCI BR2 primer.
For match bullets, the 155gr, 168gr and 178gr AMax are all wonderfully accurate. However, the 165gr SST may be flatter shooting then these.
The Interbond is also very accurate and flatter shooting then the SST but are getting pricey.
The Matchkings you mentioned will work but the Hornady's will give you an advantage due to higher vel at similar BC. Yes, the SST's have a very high BC for their bullet weight. Substantially cheaper too.
