Here is my homework on my FN 270 Win.
I bought an early 50’s FN Deluxe in 270 Win. It has a 24” barrel. Someone had fully bedded barrel and it shot awful. After rebidding, I took the thing to the range and accuracy improved but it does not like 130’s. However, it shoots 150’s well. Of the 130’s, it shot Nosler 130’s the best, which basically proves nothing. I bought a bunch of pulled 130 grain Federal Fusion bullets and those have not done well, maybe they were damaged by being pulled.
I have lots of 4350, some IMR, some H4350, and lots of AA4350. The 4350 series are all excellent powders and very versatile, shoot well in many medium capacity cartridges. I was disappointed with the velocities I got with my 130 Noslers’ and 55.0 grs H4350. I wanted 3000 fps and I did not get it. The only ammunition which gave 3000 fps was Federal factory. My rifle shot excellent groups the 150’s but the velocity is disappointing. I get better velocities with 150’s in a 308 Win. The Gunclub President asked me why I was fooling around with any other powder than 4831, and he gave me a pound to try. I will load up some and give that powder a test eventually.
Anyway, as you can see, I shot a lot of different 130’s with 55.0 grains IMR 4350, I tested Factory ammunition for a reality check on velocities. I tried Varget, IMR 4064, 4064 was more promising, but I think the 4350 series of powders were the most consistent.
