700 Police 300 win mag question

[Aimsmall55]

Ok, so I have a standard remington pss with the exception of a badger muzzle break. I reload 210 bergers for it and it has always been a one hole gun at 100 yards. BUT for some reason here lately it has been all over the place. I checked out everything and all was a go as far as functionallity. I know that this has probably been posted about a million times but any thoughts as to why this is happening? by the way rings are badger rings, scope isa 6x24x50 pst. thanks

How many rounds do you have down the tube and do you have a way to measure to see how much the throat has eroded?

Re: 700 Police 300 win mag question

probably 400 rounds, I got a guy who can measure throat erosion. just havent taken it to that point yet. Don't get me wrong, this is only probably 10 rounds I have shot that aren't acting right. just have to dwell a little deeper i guess

I take it you have checked the torque on all base screws, action, all the obvious stuff, etc. I would bet throat erosion isn't an issue yet, however with the 300 W.M. fouling at the throat can build up rather quickly. I'd give it a good cleaning, another once over, and go from there. Keep us posted. CKruse

Check the exit hole of the brake for bullet strikes also. Doesn't take much of a touch to fling them all over the place.

You need to check your throat VLD's can be quite picky about jump.If that checks out I'd guess either a loose mount or ring or the scope shit the bed.All easy enough to check just eliminate one thing at a time.

Also check bullet seating depth. .002" difference will make my groups open up above moa. I have to seat bergers in the lands on my rifle.

Re: 700 Police 300 win mag question

what kind of scope? could you have lost the nitrogen in it? or may be your powder if you reload i have had a case of bad powder that caused a similar issue because of the time of purchase diffrence caused me some trouble

Vortex pst 6x24x50. Scope is ok. Need to check headspace

Re: 700 Police 300 win mag question

Try cleaning it with Wipe Out followed by Shooters Choice after checking everything, mine start doing the same thing after about 100 rounds and usually a more in-depth cleaning cures it.
