45 raptor powder info

[smokin502]

I just finished a 45 raptor build and need to find the best powder to use. It's too expensive to buy a bunch and try them out. I just need a good starting point. Thx in advance

AR or bolt gun?
What weight bullet?
Barrel length?

AR10, 240-300gr, and 16" barrel

I have a 24" barrel on my 45 Raptor AR
I've used 250 and 275 grain bullets.
I had the best luck with the 275s
As for powders...
H110 had the widest ES by far, cold bore, warm barrel it didn't matter, and I will not use it any more.
W296 Had a great ES with cold bore shots, but once the barrel has 3 shots on it (let's say 30 seconds apart, the ES's and groups got bigger.
Alliant 300-MP is my go to powder not with my 45 Raptor
I get the fastest velocities, tightest ES, and best groups with it.
As well as the least amount of primer pressure signs.
Oh ya, you're going to want to get a HP bolt with a smaller firing pin for your 45 Raptor
JP or Fulton sells the kits.

Good Luck

Have any experience with win296? Seems to work well for the 460 s&w all weights. Using for very short range, 100yds max. Mainly for hog hunting, 40 to 60 yd shots.

Yup, its posted above as W296.

What's your twist rate?

And most likely be using 300 xtp mag bullets
