To DR4NRA, If you want a good fast load with reasonable pressures try a 40g Sierra and work up to 34g of H4198 and Rem 9 !/2. I get 4275 fps. out of my 26" barreled Ruger and often better than 1/2 moa accuracy. Seating depth of 68mm works best in my rifle and is probably as good a place as any to start, also the 35g Barnes works quite well with this formula but can give on again off again accuracy. Am not 100 % sure why this sort of behaviour occurs but it could be that the barrel is just not clean enough or they might be simply senesitive to a change in conditions. Cheers Murphy.
Hey Murphy, not really into the ultra fast loads. The one I loaded was just for the fun of it. I was looking at 40 gr loads for a 223, and saw that Accurate had a load for the SWift that was 4415 fps. So being the curious guy that I am, I just happened to have some 2700 and 40 gr Sierras. Well when the stars align like that I just had to try.
At this point my go to loads for my Swift are still 36.5 grs Varget and 52 Sierra, 36 grs RL15 and 52 sierra, and 39 grs 2700 with a 55 gr SBK. They arent the fastest in the world, but they sure are accurate, and I wont have to send it back to Cooper for another barrel anytime soon.
Nothing wrong with the 250 AI, Its just a 40 yr love affair with the Swift.
