I'm hoping someone might have some reloading data for some North Fork 458Lott information on their 450gr SP bullets. I have emailed them for the information, no response. It's been 3 weeks and would like to have a good starting point. Heck I need to make sure I have the correct powder.

I have no problem using Barnes TSX reloading data and working my way up.

Thank you in advance.
 
Wish I could contribute but I'm just going to pull up a chair to this campfire so I can listen in...
 
Well I'm going to start with this information. It will be next week before I can start. Will update on findings.

Hi
Sorry that we didnt answer you. I cant find any email about 458 lott in our system. Were did you send that email?
For 458 lott we have the following loaddata right now. We work to have some more in the future.

Warning: These loads are not valid with substitutions of different bullets of the same weight. Variations in bullet material and length will alter net case capacity, pressure and velocity results. Primer selection is specific and primer types are not interchangeable. This data represents load development in our firearms and test equipment and may easily differ in other rifles. All loads should be reduced by 8%, and developed following safe handloading practices as represented in established reloading manuals produced by component manufacturers. If you are unfamiliar with proper reloading techniques, please have our bullets loaded by an experienced company.

Have always found North Fork (Reloading International) to be helpful. They are in the buisness to stay has been my un associated opinion.
Good info but now would ask for the info on a 500 gr bullet in the 458 Lott.

Would you provide reloading info on your 500 gr bullets in the 458 Lott. Thanks
 
Something you should take note of and change on the data.......

Under the 300 NF Premium Soft... SS and the 325 NF CPS...... I am seeing only "4198" listed, it should list as H-4198....... Do not confuse with IMR......... The powder used is H-4198.............
 
So IMR4895 82gr seems to shoot well with the 450gr.

2338fps avg and stacking up.

Hi.

Do you have any reloading data on 470NE with these bullets?
 
I have used the same data as the Swift A Frame. North Fork bullets are bore riders so pressure will be less than listed for just about any other bullet if not every bullet data. I start out 2 grains less than max listed and most of the time I get higher velocities than data lists….+1 for North Forks.

After our last trip, I'm sold on North Fork bullets. Had over 4' of penetration on a lion. 450gr going 2350fps. Very accurate bullets, very happy with the performance.
 
did a lot of testing on the Lott and settled on IMR-4320, some years ago, but suspect lots of todays powders will work, as II recall I used 8o grains and worked up to 83 , for 2350 fps with a 500 gr bullet w/o problems in hot weather...Lots recoil with that caliber, such that I opted for the 416 Rem and 404 J.
 
The way it's coming up for me, I believe the column headers are off and should adjust to the right by 1 column.

Made it to Augusta Georgia yesterday for a meeting, hunt bookings are looking good for 2026 and 2027, had a great time on our Alabama safari shot a rutting deer at 200 yards with 7mm PRC near Huntsville and then headed on to Butler Alabama and semi guided my first deer ever shot a very nice broken off 8 point with hunter there and spend a few days on 1100 acres hunting preserve awesome place!

I am righthanded, so not interested in the rifle, but I have a 375 RUM and 350 gr bullet loading data is very hard to come by. If you could reply with information regarding your loads I would greatly appreciate it. Thank you, Ray Boone, Leavenworth, WA

Hello - I was looking at your post from several years ago regarding the Winchester 300 H&H. Any chance you still have the lefty M70 300 H&H for sale?
Thank you, Mike

An excellent AH member right here! I had a fantastic transaction with Hornedfrogbbq (I was the seller). His communication was first rate, payment was extremely fast, and I would have absolutely no reservations at all dealing with him again. Thank you, F!
