Another bullet test

[velvetant]

Remington 700CDL in 300 win mag.
30 Cal 180gr AccuBond @3150 fps fired into water filled gallon milk jugs@20 yards. went through 4 jugs and stopped in the 5th one. Retained weigh is 111 grains
I was out trying some Retumbo and 200gr Partitions, It shot like partitions do in my rifle..... 1.25"-1.50" which is more then adequate for hunting but not impressive. I was getting right at 3000 fps in my 26" barrel
The 180gr AccuBond shot the same 1.25"-1.5", again more then adequate for hunting. First time trying Accubonds in this rifle
I tried some Retumbo with the 180gr AccuBond 81gr gives me the above mentioned load of 3150 fps. Played with seating depth also to no avail.
My normal hunting load is 80gr H1000 with a 180gr NPT@3090fps and groups 1.25"-1.50"
For some reason I was way under the loads Hodgdon listed for Retumbo, 78gr with a 200 NPT gave me 3000 fps

That looks pretty good for 20ft! Seems like it held up well to me. Your getting some great speeds out of your 300 with 200's. I will have to give those two a try. Scotty

 

[FOTIS]

Can definitely live with that!

Pretty darn impressive how those Accubonds hold together! It had to make an impression on your water jugs!! I was going to try some of the same after hunting season is over. Thanks for the pictures.

 

[SJB358]

It seems like at 20 yards he mighta got wet. I know when I put the 275gr Speer into water jugs at 50 yards, it put jugs in about a 20 yard circle or better! I have about 20 jugs. Need to find something cool to shoot into them! Scotty

I know that water, paper, elk, deer, hogs all have different consistencies of mass but I sure like the looks of those bullets. Wonder if one put a deers rib cage behind one or two of the jugs then tried to hit a rib if anything could be learned. I wll volunteer the rib cage very sson. I think Scotty already has a couple. Still seeing those pictures gives one a lot of confidence in the AB. I have some 3 gallon sized plactic jugs that had cat sand in them I want to try this at a longer range with them.:grin:

That's my next test. I know they will survive at point blank range.
I will now set them out at 500 yards to see how they expand.

 

[SJB358]

That'll be a cool test test. Sorry, put my rib cages out for coyote bait at my buddies place! Scotty

I was wondering.... Is the Partitions contruction and durability thae same in any caliber and in any weight?

 

[SJB358]

They all seem the same to me. I think the heavier caliber bullets in the bigger calibers seem to have the PT further forward to limit expansion a little. Looking at the 225gr PT for the 358 has a PT that is a little further back, seems like to have a little bigger mushroom. The 250gr 358 is a little further forward, kinda like the 250gr 338 bullet. Either way, they all look and act the same to me. Scotty

 

[FOTIS]

I dio not know whether they are the same or not but I do know they all act in the similar fashion we all are use to.

"I was wondering.... Is the Partitions contruction and durability thae same in any caliber and in any weight?"

The various Partitions I've shot into game have all exited, so I don't have any recovered bullets to show. From what I've read (mostly from John Barsness, whom I trust completely on these matters) Nosler controls the performance of the various Partition bullets by varying both the jacket thickness and the position of the Partition itself.

According to Barsness, the heavier bullets intended for bigger game have the Partition moved farther forward in the bullet. This decreases the amount of bullet avail to expand, and increases the amount of bullet retained in the rear portion, which penetrates deeply. He also stated that the lighter Partition bullets, intended primarily for deer, have the Partition farther back, which provides more material up front for expansion.

Makes sense to me - but I haven't been able to keep one in game yet.

BTW - cool test Velvetant - thanks. I usually stress test the bullets at 20 yards myself. Convenient at the range, and it puts a hurt on the bullet for sure.

I'm really growing fond of these Accubonds...

I filed down a 130 grain .270 and a 150 grain .270 and seen the difference.... Barness is correct.

Thats great to hear, cause the 150gr PT is my do it all bullet for my 270WSM. They are insanely accurate and I can imagine would do the trick on anything here in the lower 48 without issues. They are long, have a great BC and SD. Plus, my 270 spits them out a little over 3100! Again, that is why it is my favorite rifle! Scotty
