................My lingering question after seeing those TEZ tests is how one put that into perspective. Like, how relevant, if at all is it to your experiences with the same bullet and how much correlation is there between the bullet hitting carpet, plywood, and water bottles compared to your hands-on experience in the woods?

Oh, do you have any experience/thoughts about the Tradition's Smackdown bullets performing in an Accura?

I'll chime in on the Barnes muzzleloading bullets, rather its the T-EZ or the TMZ.

I have shot so much game with those bullets its insane. I've shot whitetail from eight feet (8') to beyond 250yds with Barnes bullets. Tracking has been extremely short, many no tracking required. IF I were still shooting production rifles, without ANY question, I'd be shooting and hunting with the Barnes bullets. You put them were you should and you'll have meat in the freezer.
Now I will say that there are some new .50cal land riders that Fury makes that I would definitely try and, they could likely beat out my most favorite bullet, BARNES. The Fury are excellent hunting bullets.

Shot placement while hunting is #2, which runs behind #1, SAFETY. All to often we read about someone losing an animal and them saying, "I put it right in the boiler room". Well many of those animals where shot somewhere totally away from the "boiler room". Or when someone says the same, then find the animal and its hit in the guts or ask. Poor shot placement with ANY bullet must be avoided at all costs. Even the best bullet, if there is a best, will not make up for poor shot placement. Take out the pump station ;)

Appreciate that. Right now, I’m leaning towards a Barnes bullet. For some reason their blue sabot went down my Accura bore with too much ease. MMB is sending me some sample 12 and 24 sabots to try. Thanks for the feedback.
 
JMO, I think you are chasing a ghost. Not saying anything against you, just that system (varaflame0 adapters, is never going to satisfy you with the leaking problem. ASG or Hankins or DI are the only systems that are a no leak that I know of. I know that any system can leak if enough pressure is applied but I believe Luke is or has worked out something for that rifle.

Comes with everything one needs except the primers.
 
Before I ask my question, are your posts referring to the comments I made about possible blowback at the range last week or are the comments even relevant to me? Thanks in advance for your reply. Always grateful for new info.

Blowback
Click to expand...
Thanks. Of all the possibilities to explain the powder residue behind the breech plug I almost have to believe that the culprit was a very dirty breech plug. I’d gone back and forth so many times with opinions as to whether or not I should clean the barrel after earache shot, 3-5 shots, or never, I went with Western Powders recommendation not to clean at all. I guess that somehow registered in my mind and just mentally skipped the breech plug. Going back to the range tomorrow for a redo. I guess I’ll somehow be able to tell if a dirty breech plug is my problem or something else.

While i like those setups it totally possible to achieve a super clean breach with a 209 including hot loads. My NULA for example is cleaner than anything ive seen yet and my Knights require little more than a quick wipe after even the longest range session. My NULA loads are pushing 32kspi+ or more and you will never reach that with a BH209 sabot load without exceeding max load data...never gunna happen.

The whole key is primer fit and just enough primer crush to prevent blowby. Best way is to keep as much of the primer IN the primer pocket as possible. A primer cant bulge when its surrounded by steel and tight tolerances. Shims or o-rings IN a primer pocket may work but it also means less primer is IN the primer pocket.

Choose the brand of primer that fits your plug the best. Set the headspace to get about .003 crush by using firing pin bushing shims. Make sure you bought plenty of those primers and preferably the same lot#s. 95% of your blowby headaches will be solved for $7 plus shipping

DONT TELL CVA ANYTHING ABOUT CRUSHING PRIMERS WHEN YOU CALL THEM

I've been chasing those shims for some time now. Always out of stock. Do you have a lead on anywhere else they can be found? I've tried machine shops and fastening places with no luck and I just carry a lot of the rubber washers .
 
Call CVA about them. I bet there is a reason they are listed but always out of stock. I imagine they want people to call before they sell them.

The ONLY thing you should tell them is your bushing is not flush and you want it flush with the frame. Tell them as little as possible.
 
If you have a set of feeler gauges you can take a simple measurement.

Loosen the bushing until it is flush with the frame
Insert a primer and close the action
If you can see daylight between the bushing and the primer get your feeler gauges.
Measure the gap

To measure how far in the frame your bushing sits you will need a micrometer that can do depth measurements (or digital caliper) but if you can take both measurements you will know how much you need to shim the bushing.

Thank. My trip back to the range tomorrow will tell me whether my dirty, uncleaned BP was the problem or I need to try the shims.
 
Several years ago, during the Great Ammunition Shortage, I could not find in CCI 209m primers. I called Western and the person I talked to recommended the Winchester 209’s. I used them and they did, to my eyes, their performance was identical to the CCI’s.
 
That is pretty much all i use is a Win209 for BH209 but i also dont have a CVA QRBP. They have been flawless though in my plugs. Nobel NSI 209/686 or 209/688 should yield similar results and fit slightly better.

I cant say if its gunna make a huge accuracy difference but it is one less variable. Leaking pressure has to be going somewhere and it sure is not helping.
 
RoJo, no more reports from the range? What did you settle on for a load for the Accura PR? I just picked one up that I can't wait to shoot.
 
Barnes 250 TEZ works very well out of my PR.

Hopefully this weekend again for me.
 
RSR, thanks. Glad to hear that I got some Barnes but 290g...... You are using BH209 or pellets?
 
I am using BH209 and along with the Barnes they really have worked well even on on good sized deer. I would probably be using the 290gr if I did not have a bunch of the 250's already.
