Thread: 270 barrel shortening for a can .

Pretty much as per title , have a 24 inch barrel that i am going to can .Thinking 20 would be about right but do 270's suffer going shorter ? going to use 145 eld's . Any thoughts or how short have you gone with your 270's ? cheers wayno

Go for that that eld is a great pill in .270 I’m sure anything north or 2800 it’s going to be brilliant

Mates unmeasured looks like 22” to me and he’s using them at 2930 from memory

Leave it long for twelve months THEN make the call. I wish I had 24" barrel on mine.

20" works well with the 145 eldx if you want a shortened 270. If you plan on shooting to 400 you're good. 24" is optimal in 270 but plenty doing well with 20 inch. Personally wouldn't go shorter than that.

My Ruger ultralight is 20 inch from factory.

Chop to 18 inches, use Norma brass and superformance powder starting at 55gr working up until you hit 2925fps which will have you sitting on max pressure. In tikka chambers that’s usually around 58gr, a lot of other chambers often a grain or two less. I have loaded this combination in 5 18 inch 270s, 3 tikkas and 2 others (only one of them mine) and has been outstanding in all of them. You’ll need a decent suppressor that can handle the higher exit pressures of the shorter barrel - I’ve used Waitaki engineering suppressors on mine but dpt with a stainless baffle will do the trick just fine

And he knows little else apart from big case, heavy pill, long barrel, big boom. Or annealing bullets

Speaks volumes that him and his website more popular with the North Americans than in NZ/Oz ... also loves the Trump Dump

Thanks guys , i think 20 will be were i head as i have shorted my other rifles to that with out to much trouble . Mickey i would leave it 24 as i myself dont usually worry about cans and a can on that makes it a bit long and my dog doesnt like with out one so it will get a trim at some stage . Probably get a DPT one i think they are pretty good

Will be a very temp sensitive load.

I've settled on RWS brass and RL 23 but appreciate those are not easy to find.

Hornady factory precision hunter was excellent, but would make sure you buy all the same lot and that it's got ADI extruded powder in it and not ball.

Make sure you have a steel baffled can design if you have a 20" .270.
As your short barrel will be very hard on the can and alloy baffles will get etched away fairly quickly.

Most versatile 270 I've had (I've had one or two) was 19" suppressed, 150lrab @2850 with 2213sc smacked over stuff as far as I could shoot. Better bullet and higher BC than the 145eld in my opinion. Would go good with reloder 23 also

Chopped a Tikka to 19" the other day for a customer, stuck a Stainless baffeled silencer on it and the customer loves it.

What do you want it to do?
