it was back in august '19 when i got my gunsmith to do a couple rifles and a pistol. the pistol had a alot of head scratching but he finally got it done. i could have picked up my rifles back in august(when they were done) but they were 1 1/2 hours(gunsmith) away from me and i decided that the guns would would stay until finished. since i am handicapable, i no longer "fix" guns. oh i'll some "fixin" up, but i reserve that for the professionals. but anyway here it was........  now is  i shoot a 280gr fn gc with 4895(i have to develop THE load) in my husqvarna m46 in 9.3x57. i have a leupold freedom in 2-7x. if it goes 3" at 100 yards(bench/5 shots), i'll be happy with that. in the area that i hunt, a 100 yards loooooooooong shot, but 30-40 yards is more likely. deer/black bear is what i hunt. i would like to load the 280gr using 4895 at 1700-1800fps but i'll see. |

Good afternoon
Looks like it should do the job ! Good looking wood on it.
A 280 grain flat nose at 1750 fps will take the "git up and go" out of most any critter.`

Looks good ! One of my most enjoyed and admired gun writers Finn Aagard heaped a lot of praise on the 9.3x57 and 9.3x62 for use on African plains game. I sure miss his writing. Anyhoo quite a capable package you have there. Those bullets look familiar too.

Just a FYI we are in developmental stages of a new bullet design in this caliber. At present it is a smooth sided (without lube grooves) 310gn (final production weight uncertain) cup base round nose powder coated. Finished diameter with coating is .368". We are awaiting a test vehicle for load development. Once developmental work is completed we plan to make these bullets available to re-loaders as well as loaded ammunition in 9.3x57 Mauser. Adding 9.3x62 and 9.3x74 in the future is at present a dream or perhaps a vision that may someday be.
In truth this is nothing more than our Tom Ballard adjustable weight paper patch designed for the 38-55 and other true 38 caliber cartridges. Instead of paper patching up to 38 caliber we are simply powder coating them for use in 9.3mm cartridges.
This powder coating of bullets designed for paper patching has worked extremely well in our 451 Gibbs so we are expanding the idea into other calibers. This serves a double duty for these molds. Its like adding tooling to the business at no additional expense which is always good!
OH BTW I used this bullet in its original intended form to fill one of our B-tags (WT doe) this past season. Fired from our long barreled 375 Whelen at a range of about 125 yards the results were devastating. I think perhaps I used an alloy a bit too soft for the 2200 fps MV this rifle pushes them to. That considered some adjustments to alloy are in order for both the 375 Whelen and the 9.3x57 with this bullet. I don't expect the 9.3x57 to be capable of equaling the velocity of the 375 Whelen with this bullet but I do expect it can reach velocities in the 2000 fps area.

I found this very interesting article on the 9.3x57 cartridge. www.ballisticstudies.com/Knowledgebase/9.3x57+Mauser.htmlIn it the author suggests that due to bullet selection the cartridge is limited to large heavy game such as moose for dependable performance. He is of course speaking of factory jacketed bullets and the fact with which I agree that the caliber has been neglected here in the USA. I hope that we can eventually offer some bullet choices in this caliber that will cover all bases from smallish size deer to big heavy boned moose, bison and elk size game. The author states that most bullets factory jacketed bullets in this caliber are intended for the Scandinavian deer, moose and when used on small WT deer its wounding effect is no better than the 30-30. Well the 30-30 has never been lacking on small deer within its range limitations but the 9.3x57 has so much more potential. Something I can say with certainty is that the deer I shot with our 310gn bullet was wounded well beyond what a 30-30 will do. The trick is going to be to get the alloy hardness adjusted to the average impact velocities it will encounter. Ideally I like to see alloy hardness in Brinnell x 100 = impact velocity. That is about the perfect situation for bullets to hold together but also expand to the classic mushroom. Since we can never predict the range (distance)for a hunting shot so also we can not predict the impact velocity what we have to is compromise with averages. So what we have to look at as an average range shot and target that hardness and the plus or minus difference will not be optimum but will perform adequately. This though is the same for any bullet jacketed or otherwise but some bullet designs will better handle the extreme opposite ends of average impact velocity. This is why we now see from many bullet manufacturers optimum performance parameters advertised on bullet and ammo boxes. Sierra has for a long time listed optimum performance parameters for all their bullet designs in their loading manuals. What I will be looking at in developing our bullets in 9.3mm is the best hardness compromise for impact velocities between what they would be at the muzzle and out to 200 yards. So in effect what I have to do is to determine my maximum muzzle velocity then calculate the velocity loss at 100 yards since that is the halfway point between muzzle and 200 and adjust the alloy hardness to be optimum at 100 yards. This will result in a bit more splash at very close range and out to the max 200 yards maybe back to the 30-30 type wound but acceptable performance from muzzle to 200 yards. That should be doable and lucky for me will require a lot of test shooting to find out. Gosh I love this job. |

"just when ya think you have all the answers, they change the question!!!" - rowdy roddy piper that sounds interesting. i never got into paper patching, but your powder coating on a smooth sided boolit is genius. did you ever consider a long flat nose instead of the round nose? i just like the fn because of the "slap" it creates on deer.  would 4895 be a good powder choice for the 310gr? i'm thinking 1800 - 1900fps would nicely fill my needs. the furthest shot the 310gr would be 125 yards, but its average shot would be 30-40 yards. hmmmmm.........maybe a 12 bhn would be good for the rn.......dang it, now you got wonderin too!!!!!!  |

"""dang it, now you got wonderin too!!!!
Ah ha got ya. That is exactly my purpose. I will here quote Albert Einstein, "" education is not the process of learning facts it is the process of learning to think """ If I have aided that process then I have accomplished my mission.
Wonderin = thinking.
