Well done. IOWA_303. The Husky's are very nice hunting rifles.
I filed out the rear sight to a wide V shape easier to see.

Note the rifle is/was also factory chambered for the 8x57 and 9.3x62 ctgs. Too, some are even barreled and chambered in .30/06.

The 8x57 and 9.3x57 have CIP maximums of 57,000psi while the old '06's current standard is 60,000psi.

As there are no CIP specs for the 9.3x57, Norma loaded it to the old obsolete ballistics of a 285 or 286gr. bullet at 2,050fps.

The rifle I had (now my Brother's 'modern' moose rifle) also had a GROOVE diameter of .370" with a minimum chamber neck diameter of .393"(many of them have .393" necks) Too- it had a small base diameter but necked up (false shouldered) 8x57's perfectly. There was no trouble in the head diameter fit and I only partial FL sized my brass - never touching the shoulder.

I have data using NA powders that all gave 1" to 1 1/4" groups at 100 meters in testing with 225gr., 232gr., 235gr., 270gr., 285gr., 286gr., 293gr. and 300gr. bullets. The odd sizes, 225, 235, 300gr were all sized down .375" bullets.

Note, even though the groove diameter is .370" - you will not be able to use bullets larger than .367" or the neck's tightness will give trouble in the form of either not fitting or dangerous pressure generation.

I loaded the 225's to 2,540fps, 232's and 235's to 2,450fps, 270's to 2,300fps, 286/7gr. to 2,200fps and the 293's and 300's at 2,175fps.

By all pressure signs, my pressures were mild using BLC2 and H4895 powders. I felt I could easily have gone higher due to barely any case expansion above the web (.0005") in one spot only on the case's sides and .001" expansion of the neck. I did not load higher as the ballistics generated were all I needed and they were accurate and easy shooting loads.
