win 748 in the .220 swift

[Alucard]

Hello. Does anyone know the starting load and the maximum load in the .220 swift using win 748? I am using Speer 50 gr TNT hollow points, or 55 gr Sierra Blitzkings. Thanks for the info guys.

Alucard ,
From The Reloading Manual for Rifle and Handgun by Nick Harvey (2nd edition) .
Starting load for 50gn is 36gns of 748 for 3640 FPS , maximum of 40 gns for 3900 . For 55gn try 35gns for starting load and 38.5gn maximum for about 3830 FPS . Work up to maximum loads with caution as I couldn't get near these maximums in my Sako.
Personally found 748 faster than optimum for the Swift . Suggest you try H4350 , work up to 43 - 44 gns with a 50gn projectile . Try 760 if you want to use ball powder .
According to my manual VV-N160 (max 46gn) gives top velocities with those bullet weights if that's what you want .

Ok, thanks alot for the data Aussie.

I have never actually tried H4350 before in the Swift. I have used IMR 4831 quite a lot and recently switched over to Reloader 15. The only reason that I am trying new powders is that I have heard that Reloader 15 is quite errosive and too hot of a powder. Any truth in that. Just a rumor that I have heard.

What kind of velocity is that 44 gr of H4350 on a 50gr bullet? Thanks.

I have used w760 for years in my 220swift (over2000 rds.with Nos.55gr B.T.'s)41.5gr, back off a grain or two in your rifle and work up.in all the testing I have done H4350 DOES NOT WORK. iF w760 DOES NOT Work for you try H414 ,IMR4831 or N550 if you want a real barrel burner.

Thanks for the tips Brian. I was thinking of trying out that win 760. I hear that it is a great powder. I will have to pick some up next time I am at the gun store. Thanks again.

Alucard , AR 2209 or H4350 as it's sold in the USA worked very well in 2 different barrels in my Sako rifle giving 3900 FPS with 50 gn Nosler BT's from a 25 inch tube . The burning rate is very similar to 760 which also gave me good accuracy but a little less velocity . The original sporter barrel shot half inch 5 shot groups with both powders . IMR 4350 works well too but is more difficult to load and requires a drop tube to get enough powder in the case for maximum velocity .

Brian , the fact that you didn't find a load using H4350 that worked in your Swift is regrettable but hardly cause to shout that it "DOES NOT WORK" . Whilst it may not have occurred to you , there are quite a few other people frequenting this forum that have learned a little about reloading over the years too . Some of them will have had different experiences to your own but generally do not find it necessary to shout you down for having a different opinion .It's called diplomacy . Try it sometime .

I have to second the W760. I use it in my 220 with bullet weights from 40 to 64 grns. My best group with 64 Berger MEF is 1.3 inches at 330 yards.
