steve_b_wales Posted August 18, 2008 Report Share Posted August 18, 2008 I've just bought some new 308 cases to load. I did a batch of 10 and tried them in my rifle to see if they were okay. When closing the bolt, there was slight resistance. My RFD who sold me the cases said that its okay, and there is no need to do anything to new cases before loading them. What's your opinion?

Browning Posted August 18, 2008 Report Share Posted August 18, 2008 I always full length resize new cases. No matter what the RFD says, brass will always get knocked about in transit. Quote Link to comment Share on other sites More sharing options...
radio1ham Posted August 18, 2008 Report Share Posted August 18, 2008 mmm maybe the neck of the case is getting into the barrel making them a tight fit maybe you should check the case length and trim to size maybe ask bob300w he seems pretty good on stuff like that Quote Link to comment Share on other sites More sharing options...
AndyCM Posted August 18, 2008 Report Share Posted August 18, 2008 I full length size & trim the last new batch of cases varied by 7 thou in length - removing that variable has to help accuracy + the necks do get bashed in transit.

bob300w Posted August 18, 2008 Report Share Posted August 18, 2008 As Radio1ham says, the only thing that needs doing, and is essential to safety, is checking case length. Anything else that you do to new cases really depends upon what you intend to shoot, benchrest, target or deer. Reaming and de-burring flash-holes and neck turning for example, are a waste of time when you are talking about 1/4 minute of deer, rather than 1/4 minute of angle.

cubix Posted August 18, 2008 Report Share Posted August 18, 2008 Slight resistance? On pushing the bolt forward? or closing it down? The latter is normal. Check the COL after you put the bullet in, it sounds like you could be hitting the rifling ? Have you tried chambering an empty un-resized case witout a bullet? My new cases were an easy loose fit, hence the need to fire form them and then just neck resize. Quote Link to comment Share on other sites More sharing options...
steve_b_wales Posted August 18, 2008 Author Report Share Posted August 18, 2008 The slight resistance is when the bolt is closed down. I tried a new case before loading it and there was a slight resistance on that as well. Quote Link to comment Share on other sites More sharing options...
cubix Posted August 18, 2008 Report Share Posted August 18, 2008 Both my 22 and 243 do that. With factory ammo and reloads. Does factory do the same in yours? Quote Link to comment Share on other sites More sharing options...
steve_b_wales Posted August 19, 2008 Author Report Share Posted August 19, 2008 I've had the odd factory load feel a bit tight when the bolt is closed down. If I go to chamber a round and find that when I slide the bolt forward, it feels tight, then I will not use that round. All of my reloads are tested (safely) by chambering them. Those that don't 'pass the test' get pulled and reloaded. Quote Link to comment Share on other sites More sharing options...
