Re: 270 Winchester build

Why not 270 WBY Mag???

It does not pass the Wall Mart Test!!!

Finally got time to test a load for group @ 100 yards...so far so good. Will have to wait till Elk Season is over to try and tighten it up at longer ranges.

I would be curious to see a picture of what you did to your barrel to get it to feed VLD bullets at home.

Nosler just announced a nice new 270 Accubond with a better BC than the old ones.

Basicly, I took a 1/2" hex drive socket and chucked it up in a Lathe...then cut the socket part back to get a 15 degree face cut...essentially made a 15 degree lapping tool.

Then got a 12" hex drive extension.

put the whole thing in a variable speed drill, and with the assistance of some valve lapping compound, lapped in a feed ramp...takes a steady hand.

Once done, I used some Hollywoods polishing compound and a polishing pad to polish it up...

Looks like new!!!

Re: 270 Winchester build

I killed 4 mule deer in 2008 and killed 5 in 2009 with a .270 I built.
Most of the shots were between 400 and 500 yards, shot prone with a 9-13" swivel bipod.
I was shooting 130 gr Nosler ballistic tips.
I used a Leica CRF rangefinder and chart made from Quicktarget calculations.
I shot them broadside aiming for the front 1/3 of the animal.
Half the deer were bang-flop, and the other half averaged 75 feet of travel.

Re: 270 Winchester build

Backed out to 200 yards and did a minni ladder test.

Loads:

56.3gr 4831sc, AVG=2788, ES=15, SD=8.5

56.5gr 4831sc, AVG=2802, ES=24, SD=9.3

56.7gr 4831sc, AVG=2813, ES=23, SD=10.6

Each test group has 5 rounds.

The 56.7gr test while statistically the worst, showed the best group. However, it is too hot. It is showing some flattened primers and some gas leakage around one primer. I will have to change powders to make this work any better. Going to try H1000 and see how that works
