Anyone know off the top of their head what the rifling twist is for a FN 98 Husqvarna in 9.3x62? I'm told they can vary from 1-14 to 1-16" Was wondering about cast bullet weights and stability.Harold
 
mbogo3....I don't have a 9.3X62 by Husky but I have three Huskys in 9.3X57... Be sure to slug your bore before you get all excited about shooting cast in these rifles...my groove dia. is .370" on 2 rifles and .371 on the other...I can only chamber .369 boolits...not good!
~One solution is to order a neck and throater reamer to increase the dia. of the neck area of the chamber to accommodate a .372 or .373 boolit...
~The other solution that might work is to neck turn your brass....

I have to many projects to mess with that for now...

I guess I'll have to wait and slug the bore when it arrives sometime later this week from T.E.C. Hopefully a guy can use cast in it to swat deer with at bush range.What's the general consencise on Graf brass quality wise?Serbian?Lyman dies? etc.............Harold

Some are reporting the standard 30-06 shell holder won't fit the Graf stuff. I forget what number holder they are using. Slooshark probably knows as he had a post on this last year here.
 
HVA used 1:14 pitch for both the X57 and the X62.

Graf brass is PPU and I use standard '06 shellholder for both the Lapua and the Graf/PPU.

Thanx ! Ken Waters in his Pet Loads reloading book tested a Husky 9.3x62 and claimed it to have a 1-16" Mine came today from T.E.C. so I can slug it and see what I've got to work with.I'll get some brass etc when the wife goes to Vegas next month.......................Harold * It needs a good cleaning ie sticky bolt and filthy bore.Suposed to be in VG condition I guess we'll see.Hope there's still rifling.Clean Bore #10 soak and off to get a suitable bronse wire bore brush.Mine has the old military floorplate and thumb cut reciever?

CZ tightened their twist in the 550/9.3x62 to accomidate the heavier 320gr sledgehammers used for African stuff.I can't see a 9.3 being shot out just neglected in the cleaning Dept.lots of crud coming out of the barrel.Harold

Jamison has been found to be crap in some cases too. The 25 Rem stuff for sure. Rim groove is not cut deep enough and it causes feed problems.

Harold,
The bore in my 9,3 was said to be "good only" but when I got it it was filthy just like yours. With only two cleaning sessions I was very pleased to find a bright shiny bore and crisp little twisty things in there taboot.
Hopefully yours ends up the same.
 
Mine was suppose to be very good, but it's a little darker toward the chamber(but not rough feeling on the brush) The grafs brass is ok brass, I want to pick up a few boxes of Prvi to have something to compare my handloads too. Personaly I would just stick with jacketed soft points, I have priv 286, hornday 286, and speer 270's on order.
 
I ended up taking a .375 bronze brush on an old broken cleaning rod and between soakings in clean Bore #10 lead/copper eater ran that up the bore with a cordless drill! Should have seen the $hit that came out!Same here bore VG and darker at throat.Mine is not a commercial action but has the thumbcut 98 FN.The bolt also binds when manipulated rapidly .Not what you want for something that may bite back.It looks like it's the bolt guide .Not sure if this can be smoothed up.It's tight otherwise with no slop.As well caveman floorplate ex-military with extra screw hole...........Harold
 
My action/floorplate is awsome shape, and the trigger has been shimmed, I hope to finatly fire it this weekend. I am hopeing that the darker throat won't hurt accuracy that badly. It didn't feel rough on the brush, or catch anything on patches so I am not to worried, pluss its only the grooves that are slightly dark, lands are smooth.

I have the hornady's on order from higginsons, should be here this week. I ordered 5 boxes of them, since they seem to be quite uncommon. 1
 
My Husky is also the thumb-cut military action. Actually, that's what I wanted more than a solid walled commercial version. I contoured the trigger guard on mine and smoothed out the military floorplate. I'm not a fan of the extra screw holes, but I didn't want to go whole hog into a replacement set of bottom metal. I wanted to build it up myself as an old time gunsmith would have and I think I accomplished basically that. I also swapped out the trigger for a Bold from Brownells and set it all in a Wood-Plus pre-fit Mauser 98 stock, also from Brownells. I added an orange Pachmeyr medium pad to it for the classic look. Then we added cross-bolts and a pin (both 1/8" 416 stainless pilfered from the Old Man's knifemaking supplies) through the wrist of the stock. If you're doing this I highly recommend getting hold of a proper crossbolt mounting jig. I didn't have one and, though it worked out in the end, using the jig would have been much easier. We end-capped the crossbolt holes with African Blackwood and added a matching grip cap to cover the wrist-pin. If I was doing it again and had more time (read: had more patience) I would have rust blued it. But alas, the rust bluing season is short in the north (as is the supply of muriatic acid) so I cold blued it. Nothing stopping me from polishing it down again and rust bluing it in the future though.

I'm using 286 Norma RNs (maybe the old equivalent of the Norma Alaska bullet?) that I got from Why Not. The rifle has a fairly long throat so I wanted to use RNs to get the bullet closer to the rifling. I had used 286 TSX's but was only getting 2000 FPS with max Barnes data and 2200 with max NPT data. I consider Nosler data safe with pretty well any other bullet as I've found over the years that Nosler Partitions generate more pressure than any other bullet, likely due to the solid mid-section (A Frames and H-Mantles likely generate pressure like the NPT but I haven't got the experience with them to say for sure but I have seen extreme pressures when a NPT was substituted in a load with Speer Hot Cor data). But I digress. The TSX shot well enough but I couldn't get the velocity without really pouring the powder to it, and even then it was so much powder that the super-long TSX wouldn't seat deep enough to cycle through the magazine. Given the construction and toughness of the TSX I think that the 250 gr TSX is more than adequate for the 9.3x62. the 286 should be reserved for the 370 Sako and 9.3x64.

Again, I'm off track. I've got the Normas shooting into 1.5"-2" with irons at 100 yards so that's as good as I can ask for. I'm getting about 2350 with 59.5 gr (IIRC, haven't got my book in front of me) of RL15 on a -5 degree day (you have to love load development in December in Saskatchewan!). That load is over what Waters by 1 grain published but seems safe in my rifle, given what the Chrony is telling me. Should be just the ticket for moose or as a second rifle next year when I go back to Africa. As an aside, I'm using Lapua brass which I bought from Hirsch (after being referred there by Ed at VBull) and CCI Large Rifle Magnum primers. The Lapua brass was excellent stuff and I would wholeheartedly recommend it despite the higher cost. It fits perfectly in my 30-06 shellholder and came, apparently, annealed. A nice touch for factory brass.
