Welcome to the forum... hope some of the information you get here is helpfull to you...
I have not shot either bullet that you asked about personally. But I also know that a freind of mine loves his Swift A-Frames would not change for the world. Therefor we have a problem, because I shoot .451/260 grain Nosler Partitions and I nothey are the best - so you can see the problem. I have no doubt that the 265 Swift, if it is an A-Frame, is an outstanding bullet...
I use to, or should day I have tried, shooting 44's from my 50 cal ML's but could never get the consistent accuracy from then as I do the .451/.452 or even .458 sized bullets.
When i first started I went right to the 44's because of their higher BC's but itdid not always work for me, then I convinced myself that the higher BC was not that relevant over the short distances that I shoot a ML.
My inexpensive bullet of choice and has also worked well as a deer hunting bulletis the Speer Gold Dot .452/250 grain.
Since I am in Idaho and my real choice of hunting is elk - I do switch to a .458/300 grain Nosler Partition PP bullet for elk or a 300 grain Gold Dot. The BC of the Gold Dot is up there .232 and it flys great.
