I just started reloading and I could use a little help. I am working up some test loads for my CZ550 American 6.5x55. I am using 140 gr Hornady SST's, Norma brass, and Fed 215 primers. I meant to get some IMR 4350 but picked up H4350 by mistake. I have read that I can interchange these, is that correct? Next question: The Hornady 7th edition manual lists a max load of 41.4 gr of IMR 4350. This is a reduced load for the old military actions. I plan on working up slowly starting out at about 38.5 gr, but I am just wondering how far past the listed data some of you guys would go. Thank you for any help.

They are NOT the same! Go on line and pull up Hodg. website. load in data for you swede.I HAVE loaded up to 2 grains over book on .257 Wby. BUT that was my rifle, and it was He!! on the brass. I usally start with the middle load in the book and work up...slowly!

I do the same start in the middle I have the same rifle I shoot 125 partitions and 129sst with h414 powder forgot how many grains of powder have to check my records but split the starting load and Max load just because u soup it up don't mean it'll shoot better

5km, how does yours do with those?

Mine shoots that load pretty dang good I can shoot half dollar size groups at a 100 yards the rifle could probably do better than that but I'm no sniper by any means I haven't experimented much with different loads for mine that load I mentioned was satisfactory for me so I stuck with that one you might try some different loads that shoot better I killed an 18 point that scored 173 last year with mine last year with those nosler 125 partitions it wasn't a very long shot I'd say about 80 yds but it ground checked that sucker so I didn't see a need to change loads that's just my opinion

I use 125 Partitions with 45 grains of H4350 in my 6.5x55. It has a 26 inch barrel on a turkish action.

Thanks for this info guys, I too am a newbie reloader, but have this exact rifle (love it) as well as 3 Milsurp Swedes. Looking forward to reloading, for them (seperately). Have Sierra 140gr and just got some Hornady 120 and 140gr bullets as well

I am hoping to get out to the range by the end of the week. I'll give a report on how it went. Thanks for the help.
