My budget .270 AI ...

[Big Jake Duke]

This is my first AI and there are more experienced and qualified members than can share more insight but my short answer is yes and yes!

Look at #7 & 8 posts in http://www.longrangehunting.com/for...r-ackley-improved-load-data-64112/index2.html

Hopefully, they'll chime in.

Don't know about more qualified, but I have tried a few loads with the AI. I have found since my re-chamber that my rifle is shooting the lights out with 130 gr bullets. I went to the Cutting Edge Bullet because I followed advice on another thread for 338's and found these offerings. BC 540 and skipping down the road with nearly 3400 fps. H4831 and I have a 25" barrel.

My first attempt with the 165's I attempted with RL19 and at 54 grains it was only running 2710. I have H4831 loaded with those bullets now and when I can I'll send 'em.

That is awesome!

OK

I have settled on a load for this years trip to Colorado. This load took the honors as I make each hunting rifle win its spot each year. The load is 63.5gr H4831 Fed match reg primer. 130 gr Cutting Edge Bullet. The CE bullet has a bc of 540. Velocity is a little over 3300fps and two shot groups are in one hole. Barrel length 25".

The only way to beat that is with a 165 Matrix Bullet and I dont have enough time left to attempt it. Infact the way the CE's are shooting I might be selling a nearly full box of Matrix's.

64 grs showed pressure signs on everything but new brass, but 63.5 seemed to be the right choice for this gun. It is a 1:10 twist and it has never shot as well as it has with these 130gr CEs.

Wish me luck this season. gun)

Just got it back Friday from my smith for a muzzle brake (JP Enterprise Beenie Cooley) install ...

Can't wait to shoot it with some new loads. gun)

 

[FEENIX]

It was windy and a bit chilly but I was able to squeeze in some range time (more fire-forming and trying out the new muzzle brake).

I wasn't looking for any accuracy load at this time but here's what I got (3 shots at 100 yards) ...

(1) 60gr 7828SSC 150gr NBT, WLR , Win brass - X=3130 FPS; SD=24

(2) 60gr H1000 150gr NBT, WLR, Win brass - X=3044 FPS; SD=11

(3) 60gr H4831SC 150gr NBT, WLR, Win brass - X=3194 FPS; SD=4

#3 has the best X, SD, and group. No signs of pressure yet.

Sorry for the quality of the video (Panasonic Lumix DMC-TS4), I should have used my rest but I couldn't cradle it well and I figure it'll show the muzzle rise/recoil better if I use a shooting bag. Unfortunately, I forgot my rear bags ... might have to re-do the video next time. Anyways, here's my initial attempt ... sorry, not good in editing. I start getting steady about the :20 or so mark ...



NOTE: I was using 175gr Matrix with 57.5gr H4831SC at 2919 FPS.

Overall, I'm very pleased thus far! gun)

Awesome! Gotta love those results. After readings this thread, I'm wanting to get my 270 Gibbs up and running! Thinking 150 Bergers would be entertaining! Need a new scope for it and to refinish the stock.

John,

Sorry mate for not sharing ... I actually thought I did but thanks for straightening me out.

Been busy lately to find some range time but here's what I got from my last range time in 4/23/2013. I ran out of H4831SC so I put that quest on hold. H4350 is the only powder I can get my hands on and I've never used it before. Anyways, I loaded up some to fireform using Win brass, 150gr NBT, and WLR primer ...

54.0 xMv=3008; SD=18
54.5 xMv=3050; SD=22
55.0 xMv=3090; SD=16
55.5 xMv=3131; SD=14

All are under 1 MOA but below is the best 5-shot group at 100 yards.

Cheers mate!

WOW, Thats is one Hot piece of Kit, when you look at the 3 shots on the right you could thread a Needle with that thing,
Let alone all 5 in such a tight group, weldone you've done such a great job and you should be proud of this One,

WTG, John

Congrats on your hunt. Been following your build and am impressed with the possibilities for my .270 Win and those Matrix. What is the weight without the scope, and did the Beenie Cooley MB make a noticeable difference?

Congrats on your cold bore work up!
Congrats on your hunt success.
