.35 Remington article live
@ 10:01 pm (GMT) |
Nathan FosterA bit of a milestone for me. Its been a long time, having to stop and write the books series etc. Now finally we are getting into the .358's. Like I say, a big deal to see this up live. Special thanks to Helmut for editing (making sense of) my notes, helping me to relate info in a way that all can understand.Note that in my own mind, I call this a threshold cartridge. It is neither a truly high velocity number nor a low velocity offering. It sits right on the fence so to speak (as far as the limitations of bullet design and potential expansion go) and to this end, is entirely effected by the ranges it is used at and also how it is hand loaded. http://www.ballisticstudies.com/Knowledgebase/.35+Remington.html |

Bryan WebsterRe: .35 Remington article liveHello Nathan. This article was well written, and I liked the detail on your assessment of the Speer Hotcor, which as you know, is my favourite bullet for my 7mm Remington Magnum in 160 grain in the soft point spitzer for moose and elk.The benefit of the Hotcor design from Speer for the .35 Remington are obvious, and I look forward to your upcoming articles on the .358 Winchester and .35 Whelen, as I plan to build rifles on both those calibers but am taking my time on it while looking for a couple Remington 700 actions. I did note that you did not discuss twist rates optimal for these bullets and the different weights used in the .35 Remington and understand why for such a mild round. If possible I would like to see some of this as part of your articles for the .358 Win and .35 Whelen. In looking into this subject I found great barrels with twist rates ranging from 1:12 to 1:16 yet no talk about velocities attainable with the range of bullet weights nor accuracy related to these twist rates and bullet weights. Bob Mavin was very helpful in this aspect, having a 1:12 twist I beleive in his .358 Winchester, along with great accuracy. |

Nathan FosterRe: .35 Remington article liveHi Bryan, good point. If I forget (a lot going on), could you please give me a reminder to re-edit and include.Will include here also. 180-200 grain bullets have been fine with 12 twist up to 2900 to 2960fps. Accuracy diminishes past this, showing need for 14 twist. The 220gr Speer FP also appears to be stable to 2900fps. Penetration / terminal performance appears to be unaffected by this increase in velocity which is well beyond its design parameters. Highly unique. Note that .358 Norma and Lane's .358 STW were 12 twist, the makers intending both to be used with 225gr pills upwards. If a person wanted to run light bullets at over 3000fps, then 14 twist would be best and this would be fine with heavier pills, especially in these magnums. I personally don't see any need to run 180-200 grain bullets past 2950fps as this simply adds unnecessary stress to the bullets when using at close ranges and 2950fps is in itself spectacular when hunting. So there are no flies on the 12 twist for me. Note that all of the .358 family have had a lot of freebore built into their designs so this also effects potential. Fast twist plus jump and the resulting yaw during engagement will effect max speeds. The 12 twist barrels from true-Flite have allowed us to shoot half inch centers with 180 to 225gr bullets so again, no problems there. Just depends on how fast you want to push things. If one were to take the Whelen reamer and run it over a .300 RUM chamber to make a .358 RUM, then they would be committed to the heavier pills- but then you would not want to run light pills in such a combo anyway. Most .358 projectiles are soft to begin with, so there is only so far you take this before running into penetration issues or as Steph pointed out a few days ago, complete carcass wastage. |
