I’ll be hard to catch today a couple of appts before I travel for work.
I went with 34 gn 2208 same as the last load. The rifle hasn’t been out in a while but she went ok last time. Targets and foxes
I hope she gets onto a pig with it to see how it goes.
I know your dislike for the cartridge and projectile. Coming from the 20” Barrel May be a handicap
I’m hoping the projectile is not all bad, I have a few boxes purchased in my travels.
These are the 95gn Hunting projectile not Varmint
I’ve used Nosler 55gn Varmint in my 26” barrelled .223 with great success including head shooting of pigs.
To date no issues with Nosler but always listening, observing and learning.
Chris you haven't chosen the best powder for the 243. Your load is probably only turning up 2600 fps out of that short barrel plus it's max load.
I would try AR2209 or AR2213Sc, both these powders should give close to 3,000fps.
Try a 44gn to a max of 47.5 of 2213Sc. The max should give 3,200 fps in a 22 inch barrel.
39 to 42 gn of 2209. Max load should give 3,100fps in a 22inch barrel. If your rifle is a Tikka t3 expect lover velocity than the book. 2 people I know and have chronoed loads for in the t3 were getting just over 2,800fps with max load and the 87gn hornaday VMax.
Have fun working up loads mate.
