Update E-tips willn't group

[Murphdog]

Well I guess that my rifle has desided that it likes 180 grain partitions. I don't spend much time shooting from a bench and my bench rest is a cheap plastic unit.
Here is the load 180 grain Partition, Winchester cases, Fed 210 primers, RL 22 60 grains, OAL 3.325. 100 yards wind light right to left . I did not have a Chronograph setup. My only measure of velocity (extremely subjective)was recoil and that was stout but not what I would call abnormally heavy.

Sorry guys but I am not getting the img to come through have to work on it. A three shot group center to center was .450" Two in one ragged hole and one just to the right. I need to figure out how to get the img thing to work because I may never shoot another group like it.

I have limited experience with the e-tips but lots with the Partition. You will be very well served with the Partition's for hunting, there are few better bullets.

What is frusterating for me is that I too have used partitions for 30 years in my 30-06 with great results. They work well on everything I have ever shot with them coyotes to bull elk all just as dead. I guess that I got caught up in the hype of newer, cooler, etc. bullets. I am sure that if I worked on it I could get E-tips to work but at this point why?

Good point, I am slowly gravitating back to Partitions for my main hunting loads. The way I look at it is this. They have great BC for lead tipped bullets, and I think they will handle any shot I am likely to get. They aren't terribly expensive, as some other premiums and in all of my rifles thus far, they have shot really well for me. I tried some of the newer ones, and I think going back to PT's is a good move for me. Scotty

Exactly - I used the 180ET in my '06 because I HAD to. It's now sighted in again with the 180AB loads I have for it. If I ever go back to CA to hunt hogs on Vandenberg AFB, I'll sight it in down there with the 180ETs.

I think your problem is, the 180gr Etip is too long for the 30-06 in general. Try the 150gr, since they shed no weight on impact the 150gr will perform better than a lead bullet of 180gr.

I have tried the e-tips in the 300 rum the 7mm rem mag and the 30-378. No luck.
nothing under 2 moa. That said I never played with seating depth. Just powder charges.

The monolithic bullets are a game changer. You can reduce the bullet weight because you get such high weight retention. I'm compelled to think lighter bullets and higher velocities whenever I consider using any of the monolithics. It knocks the older philosophy (which still holds with cup-and-core bullets) of greater mass.

 

[Murphdog]

Drew first blood with new 30-06- using my Partition load. Coyote 250 yards trot; not much left caught the off side shoulder. Not the ideal coyote rifle but that was what I happened to be packin. Griz are very bad this fall so until they hit their dens I am packin the 06 or the 358 win.

I've had better luck with Accubonds than the E-Tips. For whatever reason the E-Tips just don't produce very good groups from my custom .308 rifle. I'd imagine that Nosler would rather not put the grooves in this bullet to avoid looking like a TSX bullet. If you recall, the Barnes X bullets were always difficult to load for until they realized the benefit of the grooves.

Several other custom bullet manufacturers are using the radial grooves and getting very good results - there must be a reason.

The E-ips need a lot of jump. My best accuracy has been at .100" off the lands.
My 280 AI with a 150 gr ET went .300", 338 RUM with a 200 gr ET went .7 and the 257 Roberts with the 100 gr ET around an inch.

With the advice from others on this group I started at .100 and have not tried anything less yet. But I think seating so deep is going to restrict the amount of powder that I can use. With 51gr of RL-17 in my 280AI I'm only getting around 2640fps and the cartridge looks faily full. But accuraccy is great.

3 shot group at 200yards.
I'm going to increase the charge and try again.

 

[SJB358]

Wow, that is some great shooting! Man, another 280AI shooting half dime sized groups, and at 200 yards! There has to be something to it! Scotty

I've been kind of waiting to see a post like this. I read a comment by North Fork just this morning referring to using a lesser weight bullet. They are under the opinion that this doesn't hold water. Now 150 to 180 is a big big difference and one I would IMO dismiss out of hand but say 165 to 180 for 308s, 130s to 140 in 6.5, 110 to 120 in 257. Barnes the biggest advocate of mono bullets say you may drop down one bullet weight. I'm no physics major or engineer I can only go by what I've seen. I have a friend that keeps reminding me that I have only shot N. American game. So my observations are limited. Does an increase of 100-150 ft/sec with a bullet that is 85-90% lighter with a weight retention of 15% more make a difference ........???????

I'm thinking bottom line here is what ever shoots the most accurate in your rifle that will consistently expand and give adequate penetration.

This is probably one of the best manufacture's website to ask this question on as they make some of the best bullets in all classes. Even Nosler's BT in a 300 Weatherby surprised me two years ago. It held together after going through a lot of deer from the wrong end.

I have to disagree. The 180ET shoots extremely acurate in my 30-06. I'm getting sub .5 MOA at 2750fps where as the 180AB gave me just a tad larger group at 2830fps. I use the same COL for both bullets, 3.39".

I am starting to feel very guilty that I couldn't get the 180 e-tips to group with Reloader 22 no matter where I seated them. Ok I have a question if I go to the 168 group E-tips (30-06) will it be more of a compressed load then the 180 assuming Reloader 22. Or would you suggest that I start with 4350 (either brand is fine with me). The more I read the more I think that the 168 may be my better option. I just can not go to the 150 grain bullet for elk, a mental thing.

 

[DrMike]

You should be just fine with the 168 grain E-Tips. I wouldn't hesitate to tackle elk with that bullet. So far, my experience indicates that it is very accurate. The 168 with RL22 will be heavily compressed. The max projected (SAAMI specs) for the 180 grain E-Tip in a 30-06 fills the case to 111.6%. The max projected load for the 168 grain E-Tip fills the case to 114.6%. You may be better off selecting a faster powder. If you like Alliant powders (I do), RL19 might work well for you.

I'm using 53.5gn of H4350 in mine at a the above mentioned COL. I went off of Hodgdon's info, starting at 52gn and stopped at 54gn. I never found the max load for H4350, as the 53.5 load was awesome.
