Looks really good ;) What brand is the brass you found that need neck turning with a 0.341 neck? Hope the Whidden dies are good stuff. Update when you have tested the 338 Lapua imp :) I go for a 33" barrel in my 300 Norma imp, and hoping for 3150-3200 fps with 220 Scenar/230 berger

Mine is very close but has a 0.572" shoulder dia. Just sent my reamer drawing to Whidden for die set. Have you received yours? Good stuff?

I think 235 is kind of between 215 and 230 Berger.I will mostly use Lapua 220 Scenar L, but don't know what throat that will fit it. Guess somewhere between 235-260

Is your's done Bjay? Accuracy and speed?

0,235" :)

Thanks :) Should be very close to 3200 fps with 230 berger in your 300 N Imp and 33-34" barrel :) I just ordered a reamer very close to yours.35 degree shoulder, same throat but just a little more bodytaper. Also ordered a 34" Krieger 1-9 barrel blank.

e How much do you think its possible to gain from 30" to 33-34" barrel in 300 Norma imp? Does anyone have experience with really long barrels in 300 Norma/IMP?

How do you think accuracy and barrel life will be on the 300 Lapua imp compared to 300 Norma imp?

Idaho, what speed did you get with max load rel 33 and 230 Berger out of your 300 imp?

I`ve read that some claim the 300 Norma is more efficient than 300 Lapua ? My rifle will be a single shot with loong barrel, and weight doesn't matter. About how much speed will i gain going for 34" instead of 32" Barrel? Think I go with a 35 degree imp with 110 grain case capacity (water)

Planning building a IMP version with 32" Krieger. Was hoping for 3150-3200 with 220 Lapua Scenar L and rel 33. Does anyone know the accuracy node for 220 SMK/Scenar and 230 Berger? Think I read somewhere that node was 3000 fps, and next node close to 3200 fps.

Has anyone reached the 3200 fps mark with 220-230gr bullets in the 300 Norma/IMP?

Hello Steve :) What is the case capacity of your Ruger? I buy 300 Blaser brass from Norma Sweden.

Straight 300 win mag or wildcat Dave?

Thanks for all the help guys :) As Dave and Brasscow says it might be too much overbore, at least if I go with minimum body taper and 35-40 degree shoulder. For pure accuracy with 215/230 Berger and 220 Scenar/240 SMK i might should have pushed the shoulder back and made a 30-35* with a case...

You can use 1-10 with 230,but i think you need 1-9 with 240?

Thanks Bjay.What is case capacity on your 35* version? Strange Tom told me the Hulk is 33* If its 37*. 336" neck?

Perfect :) Maby my 300 Blaser imp is all i need for the 220/230 grains bullets. The case capacity is just above win mag, but 404 based with a longer neck,0.200 throat and good brass from Norma. I`ve heard a lot of good things about the 30x68 cartridge. Is your improved with less body taper and...

Thanks Dave :) I just ordered my first "wildcat/improved" reamer (300 Blaser 37.5deg imp with 300 Dakota body taper.) . Think the case capacity will be around 95 grain of water. What do you think the perfect case capacity for pure accuracy will be for 220 Scenar, 215/230 Berger?

Thanks for the quick reply bjay. I asked Tom yesterday and he told me 33 deg on the Hulk.Hmm.. Does your 35 degree use standard 300 Norma body taper, or did you go less?
