Just load with H4350 to the pressure appropriate for your rifle. I use 44 grn IMR4350 with the Hornady 175 grn RN in my Chilean 1895 Mauser. This is an ironsighted military rifle but it is like mint new condition and very accurate with groups close to 1".

I use the 175 grs bullets in my two 7x57. A lot! 45 grs of any of the 4350s is a good all around load for 2450/2500 f/s depending of all the other components and the rifle. Not a maximum but a normal load. The same with 50 grs of R22. Anyway, check the riffling twist of your Husqvarna. These rifles were made with 1-in-11" riffling twist. Rather marginal for 175 grs bullets. Perhaps the short lenght 175 round nose works reasonable well.
My opinion; I no longer use heavy bullets in my 7mm; I find 140s and 150s to be faster killers on the sizes of game I use it for. And I had my reamer ground with a shorter throat so as to get more accuracy, and velocity out of them. I didn't like the very long throat for the 175s. I save the 175s for my 280 Ack Imp. IE, I have reverted to the old Rigby High Velocity loads.

+1. I found the 175 grains just too slow in the 7x57 and would be likewise in the 7mm-08 if they were not so compromised by a short magazine to start with. Always had far quicker killing effects with 140-145 grains at 2,800-2,900 fps MV in the 7x57 and stuck to 160 grains at 3,000 FPS MV in my 7x61 for even better killing at any range of any 7mm.

My '52 FN comercial 98 loves the 175gn Hornadys. It shoots them around an inch @ 2400fps @ 100yds, using 45gns of H4350. I've taken two small does, shot behind the shoulder and two 100-125lb pigs shot through at least one shoulder. All four were pass throughs. I'm hunting with it this year, when I know shots will be 100yds or so. capt david
"It's not how hard you hit 'em, it's where you hit 'em." The 30-06 will, with the right bullet, successfully take any game animal in North America up to 300yds. Get closer!

For myself, I cant get past the 160gn bullet weight for the 7x57 and the Woodleigh PP over 46gn H4350 gets me to 2700fps with excellent accuracy and of course the confidence that comes with this.
Here are a couple of videos that Tophet1 has previously shown on penetration tests of 7mm bullets in the 7x57 (and a 7mmRM) The 160gn Woodleigh penetration at 2400 - 7x57 and 2900 - 7mm rm showed that at 2700fps as my rifle producess is the best compromise between penetration and expansion.Nothing more could be required in this majestic old - new cartridge.
