how many rounds have you put down that 22.250? i read somewhere barrels were only good for 2000 rounds, or should i say at about 2000 rounds throat erosion started to become an issue. guess thats the problem with those smoking fast rounds.
I had shot well over that thru the first one (barrel) . I replaced it with a new barrel at dakota arms with an added two inches and ported.Shot over 1000 thru the new one since April. I never realy saw much accuracy drop in either barrel, just wanted to get a little more distance and less jump. Need to keep an eye on those pressures !!! flattened primers are a good indicator.
Airbourne id like to hear about this load care to share?
I had to dig into my old reloading equipment to find a box of rounds with the reload data in them. It has been quite some time since I loaded for this caliber and never got the oppertunity to hunt whitetails with them. the loads I worked with last where Speer 70 gr semi spitzers backed by 25.0 - 25.8 gr Winchester 748 and cci 450 magnum primers. I do not have access to a ballistics lab and/or ballistics gelitan so all my testing was done with somewhat primitive measures.(12" water soaked telephone books). the bullets penetrated at least halfway into the books and expanded as I had hoped and never exited the books, expending all their energy on the target. The bullets fragmented considerably as I also hoped for and I recovered an estimated 30% or less of the original bullets intact. I think these tests were done at 50 yds but I am not sure. My goals were to utilize the heaviest bullet I could find that would literally explode after entering the body cavity of the deer and take out all the vital organs with the resulting fragmentation. additional testing was going to continue with Sierra 60 gr hp and Sierra Match King 69 gr HPBT-MATCH. the latter would have been interesting as the box indicates 7-10" twist bbls only and the remington 700 has a 1-12 twist.
All references to loading data above are for conversational purposes only, you should start with base loads from a reputable reloading manual and work safely from there. not what someone else has done as typos and errors are possible
