My 28" is not that much faster than Rockwalls 26", but thats only one test?Would a 24" barrel be too short to fully utilize this round?
I'll be running a suppressor and keep going back and forth on whether I should go with a 26" or 24" proof barrel..
What is the reasoning for the heavier barrel? Is it for recoil? I was thinking one step below the Bartlein 3b in a 26" 5R or the same from Rock Creek. Don't want the hunting rifle to become too heavy.
Yes, you should be able run the 220 easily over 3000' with a 26" barrel, even with H1000.Hi Rich, it will be possible to reach 3000ps + with ELDX of 220gn and the 30 Sherman magnum with a CF 26" 1: 9.4 twist Proof barrel ?, obviously without overpressure. Do I need a longer barrel?
I am very interested to know if this is possible to achieve with H1000 powder.
I opened a thread that discusses the different options of .30 cartridges available, to reach that mark, and appears 30 SM, 300 PRC, 30 Nosler, RUM, 300 Norma mag, etc.
Great!!, Can you estimate how much pressure you are working with?Yes, you should be able run the 220 easily over 3000' with a 26" barrel, even with H1000.
You should be able to run a 220 at 3000+ well within saami for a prcGreat!!, Can you estimate how much pressure you are working with?
The reamer that you sell, contemplates the use of the new bullets of 245, 250, etc ?, I mean to have long throats. What I obviously want to avoid is having to put the boat tails inside the powder column.
On a side note, I did have good luck jumping the 156 in several guns, at .080 off it would fit in a standard rem mag box....obviously not optimum and limits capacity some as well as seating adjustment ability, but I was still able to achieve good accuracy from .005 off all the way out to .125" off in the different guns I tested them in. Not sure if this bullet would be the same, but I myself would still try ha haYou should be able to run a 220 at 3000+ well within saami for a prc
TheFB was set up for a 230 Berger at about .040" up into the neck. It should run the heavier bullets just fine but you need 3.8 mag length for the 245 Berger, etc. 3.8"
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
