NP partition V Speer load

[WhelanLad]

Fellows, would anyone here have loaded Nosler partitions, but also SPEER SP side by side before an testd the poi?
they seemingly look very alike,............. shapes an all......

im wondering just how close they shoots!

i could actually pull a NP and jam in the SPEER myself i guess- now this seems kind of worthless -- but you guys might of tried it.


if it looked alike, did it shoot alike?

I recently did a test through a 7-08 with 140 grain Speer Hot Core SPFB bullet vs Nosler Partition 140 semi spitzer flat base.

The Nosler bullet has less of an ogive and has a longer bearing surface than the Speer Hot Core.

Velocities are slightly different, with the Noslers being appx 100+fps slower with an identical powder charge to the Speer.

Points of impact were different as well, likely because the harmonics of the barrel differed slightly when fired.

The Noslers tend to shoot slightly lower and off in the direction of the twist in the barrel.

The twist in the 7-08, Mod 7 Remington, with a take off Model 700, 22 inch barrel was right hand, so the POI was slightly to the right and low from the same load with the Speer bullets.

I had to add 3.5 grains of the powder I was using to get the same velocities from the Nosler bullets.

This definitely showed an increase in pressures and even though the elevation was close to identical, there was still at least a moa of POA to the right.

If your shots are under 300 yards I don't believe it will make much difference to the game animals you're hunting, unless they are quite small.

I tried it with 180 grs in a .30/06. I can't recall the details exactly, but the difference was 3-4" at 100 yds, with, I think, the Speers shooting to the left of the Noslers. Everything else about the load stayed the same, I just changed the bullet.

i had the luck of 9.3 bullets with the hornady 286 grains usable at the range only and the nosler partition so i find the right partner for training.

i got similar result with the 200 grains woodleigh and 200 grains nosler partition but both now are too expensive to waste i may try with some speer to see where it goes again all in varget ...

 

[WhelanLad]

Cool Thanks guys!!

yeah prices in the .358 are high, i should have enough for me now without wasting in to dirt, thats what my 3006 is now for.

i didnt wonder RE bearing surfaces / pressure that is always going to alter.

Finding Speer 9.3 diameter bullets is going to be a chore in itself.

Speer makes several different types of bullets and has an exclusive "Hot Core" process they use when making up their bullets.

The Trophy Bonded Bear Claw bullets are bone crushers. They have a solid base, for half their length and the rest is filled with molten lead at 900F, then swaged into shape. I've never been able to recover one. They don't make them in 9.3mm

They make them in most other calibers though.

Their next toughest bullet is the Grand Slam, then the Mag Tip. Both of these are also Hot Core and perform very well on game, even at ranges around 25 meters at higher velocities. I shot a Moose a few years ago, using the 225 gr Mag Tip/2700fps in my 338-06 at just over 30 meters and the exit hole out of the far side, after going through a rib was appx 2cm across.

I realize that isn't any screaming hell for velocity, especially from the larger magnums, like the 338 Ultra Mag but that's still pretty good performance at such up close and personal ranges.

In other rifles, such as the 8x57/7x57/30-06/308Win and 270Win, I use the Speer Hot Core bullets, which are cup and cone types, with lead Spire Point, Flat Base bullets for hunting Deer and Bear, when I can find them more than a box at a time. I like to purchase several boxes from the same lot#.

I load these cartridges up with intermediate and heavy for caliber bullets at velocities that seldom exceed 2900fps.

I've yet been able to recover a bullet from an animal, even Deer/Bears shot at close ranges, 50-100yds from blinds or tree stands. (my tree stand days are over, unless it's a permanent large platform type and not the ''walk the stand up the tree type''

I just purchased some Speer 7mm Hot Core, 145 grain Grand Slam bullets from BUDGET SHOOTER SUPPLY.

The price on these is very reasonable. $155 shipped to my doorstep for 200 bullets.

I didn't look at any of the other calibers to see if they had these in other calibers.

I picked up some 196 grain, 8mm Speer Hot Core bullets from Henry last fall. Excellent accuracy, with well made components.

I also find that Speer bullets don't seem to foul as much as some other types, especially Nosler and Barnes.

speer is making a great bullet in 9.3 and i got few boxes for the 9.3x57. only 270 grains if it matters for some.

in the bullet test i did the speer did pretty good for a cup and core bullet. again on the .366 ones and not the 9.3x64 or any higher speed end ones

last bear my wife killed with the 200 grains partition loaded very mildly was so great but bullet not recovered and no rib bones destroyed we called it the sorcerer mysterious bullet.

Their bullets are cup and core but the cores aren't billets, swaged into place, with the hope that friction alone will bond the lead to the inside of the cup. They pore molten lead, 900F, into their cups and swage them to shape once they've cooled sufficiently.

Supposedly this gives the lead appx 10% better adherance over the press method.

I have numerous boxes of those Speers (early on they were about the only 9.3 bullets you could find in Canada). Use them in the 9.3z57, 9.3x60, 9.3x62 and 9.3x74R. Works well in all of them.- dan

just to confirm that 4 bullets 200 grains nosler partition and woodleigh sp were touching each other so it is a match again for my combo varget and col.

yes it is interesting that bullet is not liked by some but once you use it is a great one. i will maybe avoid for bison but that is about it for the rest it will be great and stronger design than the cup and core may show,.
