130 E-TIP, .270

[SJB358]

It,s a great bullet and worth the time. I think it would be the cats meow in the WSM. You should try it Scotty.

That's great news.

I think your right about it being a great bullet, Mike is smashing moose and elk to the ground with his 270WSM and 130ET's.. Maybe I am missing the boat?

If I see some as 2nds I think I may grab some and see what they do in the little WSM..

The 130 grain E-Tip is certainly serving me well in my 270 WSM, Scotty. I really like the way that bullet works.

 

[SJB358]

I know Mike. You are really impressing me with that bullet. I guess I have such a good load for the 150PT I am scared to try much else. Plus, I have about 150 of the 150PT Golds that shoot really well too..

 

[DrMike]

Nothing wrong with the 150s, especially those 150 Partition Golds. It will drop about anything. I'm pleased with the 130 grain E-Tip, however. I can see that it would serve very well in the 270 Win, as well.

 

[SJB358]

I have a bunch of them Mike. Really wanna plant one in an elk if I can. Or maybe Brandon runs it for his first elk!

Thanks for the welcome Hubcap and DrMike. Glad to hear your results were positive Hubcap. I noticed you were able to reach a powder charge of 1 grain over max with H4350. Were you able to reach max loads with both 4831's and 7828? I was planning on starting three grains below max and slowly working my way up.

The only powder I went one grain over listed max was with IMR-4350. I did that with a ladder test only. My initial groups with IMR-4350 were all shot with 55.2 grains. I have not had any pressure signs at all with 4350. However I do believe the slower powders will get better velocity and accuracy with listed max charges. Still need to set up the chrony and check the speeds with those powders. As I collect more data I will be happy to post more info.
