lite and fast
I started shooting the 243 in a Rem. 600 in 1965. Ten years later I replaced it with a Rem 700 varminter. There wasn't the wide selection of bullets then, no plastic tips of any kind. I pretty much stayed with Sierra's in 60 gr. H.P. flat base and 70 gr. HPBT match. Both were fast, 37-3800fps, flat shooting and accurate.
Groups were less than 1/2 inch at 100 and at times 5/8" at 200. It didn't take long to figure out that under all that hair ole Wiley wasn't very big. We did most of our shooting at around 6000 foot altitude on flat snow covered ground. Range estimation was difficult at best. That had a lot to do with our choice of bullets.
If I were to start over now I would for sure try the Ballistic tips, and v-max bullets. I’ve had good luck with them in both 222 and 22-250. I would still stay on the lite, fast side
