I have a traditional .54 that has a 1:24" twist. Previously I used 535 grain conicals but that seemed like a bit much for some of the game I would hunt. I used them with 80 grain powder and got a reasonable trajectory to 100-yards. Most of the .54 conicals that I see are in the mid-upper 300 grain range, but I shoot 300 grain conicals in my .50 and the .54 PRB's are 230 grain. So, I found some old stock .54 conicals that are 430 grain. I think they will work well with the ROT and have enough weight to offer a bit more than my .50 conicals or the PRB if I feel the need. I am hoping they will run a bit faster than 535's with the same charge and offer a little flatter trajectory. There are a few critters that I may lean towards the heavier .54 conicals and those are Nilgai and maybe Eland. Otherwise, I will use them when I just feel like using that rifle and I know the 430's are plenty for deer/hogs/bear and even elk. Does anyone have experience with .54 conicals or some information for me to consider before I sight in and get serious with these 430's?
