Swift A Frame 270gr (this will help)
Jannie, I use H-4350 for my 300 Gr. SAFs), however it isn't listed for the 270(s). My book shows three Hodgdon powders H-380,H-4895 & Varget. Which of these powders do you have available? What length barrel are you using?
Hi it seems we have H-4895 & Varget available, barrel length is 24"
I’ve never tried H4895, but I am soon because it will not be compressed and should give good velocity. I’m just looking for a alternative to compressing my IMR4350. Also H414 gives top velocities in all my load manuals for 300grain loads, but will be slightly compressed also.
Velocity is nice, but what load gives you the best accuracy? The combination of the two is what I strive for.
My H414 load at 2525 gives me about 1 inch or a little over at 100 yards, which I good enough. I should add that I’ve never loaded a swift bullet(never needed a premium as my state is shotgun only) but I shoot and reload a lot. I was just saying what powders from hodgon I have used and what I liked and disliked about them.
Sent you a pm with the information you seek
Thanks will let you know if I don't get it.
I'm in the process of working up a .308 load with the 165 gr A-Frame right now.
I did some initial loads with RL-17 this morning. It's not in the swift manual, but Alliant online does show some loads (for Speer 165 BTSP at COL 2.800" minimum). MAX @50.0 grains is said to do 2,739 fps with the Speer.
Three 165 AF at COL 2.770" loaded at 49.0 grains RL17 at did .75" from the 22" Franchi at 100 meters.
One (only) ran 2,699 fps using a MV3 (Magnetospeed).
These are compressed loads - powder is about half way up the neck.
I only loaded one at 49.5 grains. It ran 2,734 fps (MV3). Temp was 70*F.
No pressure signs with any that I could see (in this specific rifle). F210 primers had rounded edges.
More testing needed.
I plan to load a handfull at 49.5 grains RL17 at same COL and see how they do.
Note, at this COL, the base of the 165 AF is slightly below the bottom of the neck. I'm waiting on a threaded case ( arrives tomorrow), to see what Max Chamber measures in the Franchi.
Oh - brass for above was new 308W Lapua. Large primer.
Funny. In the US, Swift is about 2X the price of Norma Oryx.
You guys overseas might take a look at loaddata.com. For about 30USD annual membership, you get access to a lot of the factory load data (Norma, Swift, Barnes, Hornady, Berger, Nosler, Speer, Sierra, and quite a number of others). About the only common bullets I've never seen any load data for there is Woodleigh.
Norma loads the Swift A-Frame in some calibers Sgt. Zim, starting at .308 diameter, but a quick search on Ammoseek found none for sale in the USA for retailers that list with Ammoseek.
Norma also loads some calibers with Swift Scirocco II projectiles, a similar search on Ammoseek turned up several retailers with Norma 6.5CM ammo loaded with Swift Scirocco II available in the USA that list with Ammoseek.
We see a very narrow portion of the full catalog of Norma's ammunition options available for retail sale in the USA vs other areas of the world.

lapua 308 brass might be thicker than Winchester or rem, and as such hold less powder, or give more pressure for the same powder.
swift is more expensive in SA too especially the A Frames
swift 9.3 bullets are about oz$3.00 per unit here in oz.
they are still worth it where applicable.
Absolutely, and thanks for the reminder!
I almost never use Rem or Winchester brass for reloads. I've been very happy with Norma/Nosler quality and that's what I usually buy. Just decided to go with Lapua for the .308. (I use Aussie surplus 7.62x51 brass for the 7.62 gas guns, which is even heavier than Lapua 308 or LC - but not by much.)
I make it a point to weigh and record case weights when I get a new brand or lot.
Just now checking against some fired Norma .308 brass (from factory 165g Oryx), there is a significant difference in case weights. Laupa at ~175 grains vs decapped Norma at 166ish. It might be worth checking to see if there more space in the Norma brass. ( Since I'm out of room.)
