Expectations of Nosler Reloads Velocity

[Idahotrophyhunter]

Question to those in the know....

...I took my Savage Long Range Hunter 6.5 creedmoor out today and did some shooting. I just shot the Hornady Factory Loads 140 grain A-Max as these are my target loads and when I bought the rifle I bought 5 boxes of them. I chronographed 6 shots through the 26" barrel and averaged 2840 FPS with a Spread average of bout 15 fps.

I am going to load 140 partitions as my hunting load, if I follow the recipe on the hornady box to a tee, (charge, primer, oal, ect) can I expect nearly the same velocity from the Nosler? Or because its a different shaped bullet, will the velocities be quite different?

 

[nvbroncrider]

Too many varibles. First starting with the different profile of the bullet might not allow you to seat Partitions at that length. Different lots on powders and such I would just do a normal start from scratch load development. Look there might be a powder that's different than the one on the box that might match up better. Ask someone for some QL data and I'm sure they will be glad to put it up.

QL projects that a maximum charge of H4831SC (46.5 grains) yields a velocity of 2843 fps with Nosler 140 grain PT, and a velocity of 2834 with a maximum charge of 46.0 grains and a 140 grain A-Max. Velocities may vary significantly in the real world, however.

This last weekend i chrongraphed two similar loads, with the major difference being the a different make of bullet, but of the same weight. The difference between the two loads was 300 fps.

I would start low, work up, and chronograph along the way.

I am looking forward to hearing about the 6.5CM though. Pretty cool round. Seems like it gets that 140 in a hurry as well. That is alot of efficiency from a smaller case. Post up some targets when you can.

I'm a little confused. I have never seen load data printed on my factory hornady ammo boxes. So I don't know how to coment to using any such data other than to use published data from a reloading manual and work up the load safely starting with the min. charge like you would for any hand load.

Hornady has nicely put reloading data on the 6.5 Creedmoor target ammo using there 120 A-Max and 140 A-Max bullets but not the hunting ammo.
Never seen it on any other factory ammo.

Fascinating, Randy. I was given two boxes of that ammunition when I got my 6.5 Creedmoo; I never even read the end flap. I used them for break-in and threw the boxes away. Thanks for posting the picture.

 

[barthowes]

that is cool. wish everyone did that.

What about a 130gr Nosler? The SD is still up there, its what I though would make a great 260rem load for deer. Just curious

IdahoTrophyHunter,

I can't say if the Partitions will be as fast as the A-max, as I've never shot any A-max through my 30-06.

However, my somewhat educated guess will be the Partitions will be slower. Partitions through my rifle are roughly 70 fps slower than Accubonds and Ballistic Tips, for the same weight and charge.

Let us know what you see!

I'd like to see as well, I load the 140 Custom Competition in my 6.5 Creedmoor although I'm using Ramshot Hunter instead of the H4350 they recommend. I'm getting just a shade under 2900 FPS. Its not quite as accurate as the 100 grain BT but its a lot flatter shooting. I have some 140 grain BTs that I picked up from SPS but I haven't shot any yet.

The Partitions have the H-mantle Partition located right at the end of the bearing surface of the jacket. This Partition acts like a solid beam of jacket, gliding metal material which causes higher compressive yield and higher internal stress than the lead slug does. Because the bullet internal stresses rise, burn temperature will be higher, gas pressures of powder burn rise and also will cause the bullet to have greater drag through the rifling because of the higher compressive stresses.

All of this will result in more heat, less velocity and slightly higher barrel pressures while pushing through the rifling. This is why Partition bullets are a little slower and have slightly higher pressures during powder burning. Nosler reloading manuals all warn you to reduce loads slightly with Partition bullets because of the higher pressures caused by the bullet construction and design.

I've never seen that warning in any Nosler manual, Speer does have that warning though for their TBBC/TBSS.

The cartridge shoots really well out of the Long Range Hunter, but the rifle is morphing a bit from what I want it for. I was going to load 140 bergers and use it to dial in long range 700-1000 yards. But I have found that I am just not proficient enough to put bullets in a kill zone that far away. So because of that its turned into a 400 yard rifle which is as far as I can consistently and accurately shoot. That is why I want to use 140 noslers. Only have to dial bout 1.2-1.4 mils for that distance.

Shoots right at MOA but im working to get it under that.

Practice buddy no one here can just step out to 1000 dope the scope pull the trigger and thump. Except the few who are shooting 1000 on a regular basis. Too many varibles unless you count them all. It can still be "that gun" just take your time it will come. Those 140 AB aren't a bad comprimise either. Good BC great game performance and affordable. Plus if you get seconds from sps you can do a ton of shooting and become a good 1000 yard marksman.

That is the truth, even a few months of not pressing the trigger on the bolt guns makes me a little rusty. Takes a little bit to get back into the groove after a long time away from the long guns.

Also note that the data provided on the factory box indicates a 28" barrel. Don't expect very many folks are getting very close to their advertised velocity on that ammo, and probably have a rude awakening if they ever run it over some sky screens in their 22" or 24 " hunting rifle...
