chamber

I was hoping for a little education about chambers and bullet sizes, specific to these new “heavy for caliber” bullets. How does chamber cut influence performance with various sized bullets? Or is it not even a thing? Specifically, I have a match chamber for a .300 PRC set for 225gr...

Hallo I have problems with calibrating the base of the 223REM Lapua brass, 6× and 15× fired. The base of the brass is so tough or big, that it is very hard to size it with my Whidden bushing Full Length sizing die. Some of the brass even stuck in my die !! No matter how much lube (RCBS or...

Hi I have strange issue with my 6.5cm rifle. My fireformed brass chambers easily But resized using SAC FL sizing die wont. (No expander, 287 bushing) I tried Hornady match grade bushing die as well. I have to bump the shoulders back about 0.0045 (1.4845)in order to chamber the sized brass...

Hi Everyone I ran the borescope through the barrel and found out the chamber area has some scratches and raised metal marks Tried to chamber a virgin brass and closed the bolt, extracted brass has the exact same marks I look at the bag of first fired rounds that I saw they have the similar...

Hey guys, I have a question for people that know about chamber reaming and neck sizes. I have a sporterized Enfield No.4 that I want to accurize, and I'm trying to avoid having to load .303 Brit. The action is already set up to run rimmed cartridges. I will have to make some tweaks to the...

Research, friends who have worked at Smith and Wesson and Remington by phone were unable to help. I will start with the back story. This gun and I have not been handloading for a long time but my son and I are sharing a renewed hobby - reloading for accuracy. In time he hopes to invest in...

I'm having a problem with my 300PRC, in that 3x brass will no longer chamber. Brass was resized and the shoulder was bumped back 0.002", just like the first two times I reloaded it. This time however the bolt is hanging up at the downstroke. Checked headspace and it is correct, same as the 2x...

Would it be advantagous to coat inside of barrel or would it cause a loss of rifling effect?Is it even possible?

I'm starting to think about building a long range hunting rifle. I'm going to be attempting to build this thing myself and I'm chambering it in 264 Win. Mag. I'm thinking I'm going to build it on a savage action (possibly a custom action, haven't decided yet) My question is... Has anyone tried...

What happens to chamber preasure if you work up a load at 1600 ft, and then go up to 6500ft. I understand that preasure will be higher if the temps are higher, but unclear about the change with altitude. Thanks

Any opinion on which produces a more accurate rifle? And which is less sensitive to carbon buildup?

How much case body to chamber clearance is suggested for a tactical (going to get dirty) rifle? How much case neck to chamber clearance? How loose should it be for reliability? How tight should it be for accuracy? 0.008"? 0.005"? 0.003"? other??? Thanks in advance, Kyle

Just got a Rock River AR rifle with a Wyled chamber and would like to know what full length die and brass recommendations you all have.. Thanks for your opinions.

Had a Pacnor barrel installed on my 280 AI. Trimmed all my brass to 2.525". 168 gr sierra hpbt seated .010 off the lands. At first I thought the necks spliting was due to work hardening, but then I noticed the ring around the neck. The neck also has a slight taper on the end starting at the...

I read that high sulfur cutting oils will dull reamers when used on stainless, is that right? what are yall using?

I have a RRA flattop with the Wylde chamber. Do i need to full length the brass every time or can i just neck size it with this chambering?

I have a GAP 308 I purchased from another member here. Very nice rifle. One caveat, My loads seem to stick in the chamber after firing.These are my "general loads" for everything I own 308. Some here have said that they are too hot. I'm not sure. These same loads function flawless in my match...

Looking for a .300 Win Mag chamber reamer for 220 gr. SMK at AICS mag length. Any suggestions?
