[QUOTE="nkyshooter, post: 2075942, member: 83787"] My 30 Sherman Magnum barrel is ordered and I hope to have it in about a month!!! I'm building this to achieve a personal goal of a 1 mile hit on a 5 gallon bucket as well as doubling as a long range hunting rifle if/when I ever get the opportunity to use it on a long range larger game hunt. It's going to be a 26" X-Caliber 5R 8 twist minimally headspaced on a Savage 110 with Accutrigger and a 20 MOA rail in an HS Precision stock with the Lapua 338 bottom metal allowing me to utilize the 3.850" 300 winmag/300 PRC magazines ... oh - and an ever important Ross Schuler 4 port brake. 😁 I'll be working up one load for 300 PRC during fire forming / break in / rifle setup and then building up a long range target load for a 1 mile load post fire forming. [B]I'm needing/looking for feedback [U]from those of you who have been loading for the 30 Sherman Magnum - OR - have Quickload[/U][/B] on using the below initial/starting loads ... I'm using the below components primarily because it is what I have and coming up with other is not trivial right now ... FYI - currently planning to use 1x fired Hornady PRC brass for this ... and my understanding is that the formed brass should have around a 98gr capacity. [B]Fireforming/Break In[/B] (H4831/Hornady 178gr Match and/or 178gr ELD-X ... unless someone has some 212 ELD-X they can spare 😜): - use the 300 PRC load data from Hornady - 76 gr of H4831 starting - work up 1gr increments to find ceiling then ladder to accuracy node [B]Long range target load[/B] (H1000/Hornady 230gr A-Tip) [U][B]post [/B]fireforming[/U]: - use the 300 PRC load data from Hornady and start in upper half of the window as low end of window working up from there - 74 gr of H1000 starting - work up in 1 gr increments to find ceiling then ladder to accuracy node All the above will be using Federal 215 match primers since that is what I have. Data I've used to come to the above conclusions include: [B]300 PRC[/B] load data from [B]Hornady [/B]shows: [LIST] [*]178gr bullet with H4831 69.1-82.5 grains [*]230gr bullet with H1000 66.9-77.5 grains [/LIST] [B]300 PRC[/B] load data from [B]Hodgdon.com[/B] shows: [LIST] [*]175gr bullet with H4831 71.5-77.3 grains [*]230gr bullet with H1000 70.4-75.7 grains [/LIST] [B]30 Nosler[/B] load data from [B]Nosler.com[/B] shows: [LIST] [*]175gr bullet with H4831 75.0-79.0 grains [*]220gr bullet with H1000 73.5-77.5 grains [/LIST] I'm hoping to get to an very accurate load (sub .5 moa) with the 230s at 2900-3000 fps or better for appox 1350 fps on a 1 mile target ... however, ballistics calculations indicate 2600fps at the muzzle with the 230gr A-Tip will keep me supersonic all the way there and I should be WELL above that even without the elusive RL26 or N570 powders. Any input on starting loads and/or concerns with my approach as outline above would be most appreciated! Thanks in advance ... Tim [/QUOTE]
