Upgrade Badger's P14

For subsonic I don't think you'd need to mess around with gas checks , just get a nice 250-300 g round nose and stuff it on top of a charge of trailboss ?

[dromia]

Theoretically you shouldn't need gas checks for sub sonic loads however each boolit and rifle are a law unto them selves and some gas check shanked boolits won't shoot a damn without a check at any velocity, you just have to test and try.

Most of us indoor 303 shooters use a 115 gn GC soupcan boolit over 4 gns of VV N310 to good effect without checks, however my No 4 T won't shoot that boolit worth a damn without a gas check fitted, put a gas check on it and its a tack driver.

Hmmm, those boolits recommended by Dromia seem pretty good. We'll have to look round and see who sells .338 Federal barrels now, and in what twists...

[Sandgroper]

You'll be looking 338 barrel blanks and most likely have to add the cost of a 338 federal reamer on top.

Walther does 338 blanks with a 1 in 10 twist. Trueflite 1 in9 and 1in 10. I would hazard a guess and say 1 in 10 would suit most bullets/boolits and be the most common twist rate available.

*Ponders*

[Sandgroper]

Get back over to the P14 thread and ejikate us about twist rates for 250 grain subsonic .338s

Well, what length is the bullet/boolit you're thinking of using? Is the one Adam suggested?

[meles meles]

That seems a very good starting point, ooman, unless you know better...

[Sandgroper]

Going by the boolit specs - a 1 in 10 twist rate is plenty.

Try Armalon ,Peter Sarony will supply a blank or a fully threaded /chambered barrel .
