27 Nosler

[JAYgs8163]

Which one is better Preferred or McGowan?

I have 3 PBB barrels. All shoot excellent. TT Bryce. Mine are 18-22" 750 straight taper fluted barrels. If I remember correctly my 7mm-08 22" barrel came in at 2# 12 oz.

Thank You Feenix. I appreciate the suggestion.

The .270TH is local LRH joke of .270Win on 700LA with 3.63 magazine COAL that provides more case capacity for 156HH and RL 26. The results were kind of surprising due to having extra freebore, long COAL and 27" Light Palma 1:8 barrel. Really nothing extraordinary except for the results. Its what the .270 should have been! The 156HH ended up topping out close to 3300 and settled load is 3200 which is pretty good for a .270Win.

That's great for a 270 win my 27 nos is 3370 and shoots great I just assumed load may be getting hot and bolt primers. Are good.
Don't imagine getting more than 4-5 reloads with nosler brass hoping Peterson starts making 27 brass

I am curious to see the actual difference between .270Win and .270AI on similar loads and rifle configuration.

Should be interesting!

The 140 needs an 8 twist. We will try and make the 150 stabilize in a 1:7.5, but if you are building a 1:7 gun, by all means use that twist. We are trying to make the new 150 stable in factory rifles with 1:7.5 barrels. I don't think your round will be any stubbier since the length of the 150 we anticipate to be <0.085" longer than the 140. Have to see how the computer modeling turns out.

The 150 gr .277 SBD2 is done and tested for BC. It is 1.635" long, stable in an 8 twist and faster. It has a G1BC = 0.710 and G7= 0.350. From a 6.8 Western and 60 gr of StaBall6.5 it gives 3080 fps from s 24" barrel and shoots .25-.4 MOA 3 shot groups at 165 yds.

So does this mean there going to be available on the website soon?

That would be around 3300fps from my 270/300WM. Hmmmnn.

Longest range .277 caliber bullet available hunting or otherwise.
