I have an FN made BLR in .243 Win. It has a 20" barrel, which as far as I know has a 1:10 twist rate. From what I know, 1:10 is the most common in .243. I have always used 85-90gn projectiles in my .243, the first being an LSA Tikka, and now the BLR. Accuracy with the BLR using 90gn Speer Hot-Cor bullets has been acceptable (hunting rifle only) so in that regard it is fine.
However I am giving some thought to loading some different construction projectiles in the same weight. My pig hunting has been in western Qld mostly, and a big pig may be 80-90kg. Not too many bigger than that where I went, not that we ever weighed any. The Hot-Cor has been a solid performer on that size animal, however I wonder if used on a bigger 100kg or more boar whether they would be a bit light on. I am thinking about Cape York porkers.......
I have always preferred to stay with 90gn due to ballistics advantage over the 100gn stuff, however that may have been true 30 years ago, but the projectile selection now is far greater. The 90gn is good with getting a nice velocity at low pressures, and nice trajectory, so I am inclined to stuck with this weight.
Given the BLR has a short barrel, what are members thoughts on projectile selection???
Do you agree with my 90gn preference?
Is there a particular BC or SD that I should look at in the short 20" barrel??
Do you reckon the 90gn Hot-Cor is solid enough construction to make the exercise of no advantage??

P.S. - No, I do not want to buy a .308.
