170gr Round Nose Partition at 308W velocities
@ 11:33 pm (GMT) |
john feyereisnHas anyone tried the 170 gr round nose partition at full 308 velocities? I am thinking of trying them on whitetail deer, I would think they would be pretty violent, but I would think the partition would stay together enough to penetrate and exit with chest shots. Shots would be mostly under 200 yds never over 300 and a possibly of very close shots.Any thoughts? |

Alvaro Piqueras Alonso-LambertiRe: 170gr Round Nose Partition at 308W velocitiesHi John,The 170 partituons seems a bit too much bullet for WT at 308w speeds. If you want keep with that design, i think the 150 will be a better option. Other good selections in my opinion will be the 165 sst or the 178 amax if you want more weight and higuer BC. |

Nathan FosterRe: 170gr Round Nose Partition at 308W velocitiesHi John, I have used just about every .30-30 bullet at .308 to .300 Win Mag speeds during the course of research.This is a bit of a catch 22 because it all comes together to produce that spectacular performance you are after at high impact velocities. Once we go below 2600fps, performance tends to even out. In this instance, apart from superior penetration, there is not a great deal of difference between this load and an SST load. So, if you want to make the most out of this, you would need to try to build a high velocity load, accurate, going around 2700fps. You would need to try to keep ranges short to optimize results. In other words, it would be a bush / woods load. As for a 200 yard load- yes, the bullet will kill cleanly but I do not see any major advantage over something like the SST unless you are after greater penetration (heavily raking shots). There will certainly be a slight disadvantage as far as trajectory and impact velocities go but I am sure you can work through this. Apart from these factors / considerations, I see no reason why you should not try this for a season. Performance is very similar to the excellent Norma Vulcan but again, penetration is superior. Actually, if you think about, its a wonder this is not already a European woods hunting factory load. After all, BC is often of least concern in these loadings. |

john feyereisnRe: 170gr Round Nose Partition at 308W velocitiesThanks both of you for the reply. I came across a box of them cheap and thought I would try them.what I am going for is the most likely chance for stopping the deer immediately, the are we hunt is heavily wooded and heavily hunted. We hunt along the edge of a petrol pipeline, so The deer are not visable until they step out into the clearing and that could be very close, but they are usually broadside. I do also have 150gr ballistic tip, sst, partition and 165 sst bullets and loads available. I have also considered trimming the metplat flat simalor to a swift a frame on a standard spitzer partition, any thoughts on this? |
