Need 7.5X55 Load Data

[0321jarhead]

Going nuts on this one. I have some Sierra 175gr HPBT and the only powder I have at this time is H4895. I have loaded up 180gr and 168gr no problem. The bullets I am doing to is some Sierra 165gr HPBT and the 175gr. I can'y find any load data on those two. The ammo I am to reload is for a K31 7.5X55 Swiss. Any safe data would really be helpful.

Anything and everything about 7.5 Swiss, check out the swiss rifle forum.

Linky goes to the reloading section.

Lucky you, have been looking for an 8lb jug of H4895!

I'm way ahead of you. It is only shown in IMR4895 for the Sierra 175gr. HPBT.

This is a real bugger for 175gr. and using H4895 for 7.5X55 Swiss...Eeerrrrr! I had been using 180gr and 168gr. with no problems. I would just like to come close as I can as the 174gr. GP11 by using 175gr and H4895.

Just use the data for the 180gr bullet which is start 37 grs and max 39 grs of H4895

True, it is only a 5gr difference. It has crossed my mind.

Jarhead--

I worked up some H4895 / 175 SMK loads with help from Latigo. I'll check my book this evening and let you know what was successful.

Great!

Jarhead,

The loads I tried with H4895 were between 36.0-39.0 gr. Velocities out of my K31 for this array (3 shots / weight in 0.5gr increments) was a total range of 125 fps-- not good.

I shot this group last of 4 arrays, so I won't go into accuracy, as I lost most shots in the holes from the previous groups. I did arrays with H4350, H4831 and RL17 at the same time. The RL17 was definitely the best, followed by H4831.

Good luck.

Good to know. I was pondering on starting out at 38.0 gr. for the 175's. Guess I'll stick with 168 and 180 gr. HPBT. In the meantime I'll hunt around for some RL17. Thanks for your help.

4064 is another option can sometimes be found, I've used it with good results with 165SGK for an awesome deer round

I use both 168 & 175 SMK with H4895 and a CCI #200 primer with good results. 41.0 grs for the 168 and 39.0 grs with the 175. Just work up slowly and you should be fine. I seat them to 2.930" if you were wondering... But this is specific to my rifle so you might want to see what you can seat them to without jamming them into the lands.
