then went to AA2700. I had two Savages 112 J's and two Ruger 77V's.
43.5-44.5g of AA2700 with a 50g Nosler; Fed 210 primer; Win case; will dump the bullet into a very tiny hole at 4000 fps. Many, many times I have head shot squirrels at 200 yards with this load as they laid in a hole with their head barely showing.
AA2700 is much easier on the throat than IMR 4064...we are talking night and day.
I used the Swifts to shoot ground squirrels and Rock chucks.
If you are shooting IMR 4064 in your Swift, you owe it to yourself and your rifle to try a lb of AA2700, this seems to be one of those loads that shoots in a lot of rifles.
Good luck!
Saw this post has been updated recently, and used this quote for a reason.
Since my last installment on this, My Cooper in the Swift has had to be rebarrelled, and my powder of choice has changed.
H-380 is no longer in the mix, great powder, 52SMK @ 4050 fps, max load, and CCI BR primer took out the barrell. I guess speed does kill.
My primary powder now is AA2700, it meters extremely well, and gives me very low E.S, and S.Ds. Velocity is likewise very good, although I do tend to download it more than I used too. This is another good reason for the 2700.
By adding 2" to the barrell (26) I am now getting aprox. 150 to 200 fps higher per charge than I was with the 24. AA2700 accomadates this very well, burns cleaner than varget or 380, and gives excellent accuracy from charges of 1 gr under starting, to max.
It works well with 50BK, 52MK, and 55 BK, Nosler BTs and their Custom Comps. Noticed no change in pressure or velocity swings in temps from 15 F to 90 F. Just a good all around powder. Also my throat seems to be holding up alot better too.
RL 15 is showing promise, but I have seen wild velocity spikes with this powder, also the S.Ds are on the high side so far. Still using Norma and RP brass and CCI BR primers.
Both these powders work real well in my 22.250 too.
