Panda 30br First Outing

[Ccrider]

What bullets were you shooting? I see you load some 125 TNT's for fowlers but couldn't see what bullets you were using for this load workup.

Thanks,
Dave

Clines 108gr. bullets.

Could not find bullets anywhere when I started with the 30br. Jim, like many others on this site, was generous and helped me out.

JIm also did me a favor with some 30BR bullets. Great guy to deal with.

Shot a target today to check the load. Not sure what happened on number 6.

 

[Ccrider]

Have not shot the Panda since April. Figured I would see if the load was still in tune. Humidity was high but wind was calm. I did not put out flags. In a hurry and very light wind.

Took a few shots to get the scope dialed in. I still shot ok after I got it together. 34.9 H4198, Cline on bullets, 205m primers, .20 off touch. Forgot to mention, velocity was 3050.

Ok Bill. What are you doing with those Cline bullets? They shoot on one hole unless you screw it up!

They absolutely shoot "lights out" These groups were shot from my M-7 Hunting 30BR from a bipod and rear bag. My BR 30BR will shoot them tighter of course.

Great shooting! I was just checking to make sure you were doing the bullets proud.

I am doing my best Bro. LOL.

Shot a few more rounds with the 34.9 H4198, .20 off hard jam. The es was great, although the velocity was down to 3045. The wind was tricky and humidity high. The gun still seemed tune to me.

I have been shooting two different lots of brass. Can’t see where one shoots any better or different than the other.

Top left are 4 ten shot groups from my Vudoo.

So...you're jumping the bullet .020? -Al

No. I misspoke on the post above when I said “touch”. Thanks for pointing it out.

I am actually .20 off of what I call “hard jam.” Hard jam is setting the bullet long and then letting the bolt push it into the case. I started at that measurement and then backed off of the lands to work up this load, primarily because I expected the gun to shoot well at hard jam.

If you use the Wheeler method, which I normally do, my final load is .003 into the lands.

Looks like Jims making a good bullet. Im putting a ppc together, Im sure it will also get a 30br barrel as well. They are just too fun.

Here is what I got moving out of the lands .005 each series. So, how would you interpret the results?Thanks

Better paper or tight against the back board you might get cleaner holes to interpret.

He definitely is. I have been able to get them to shoot small in two different guns using different powders.

Decided to try the short load work up method described by RG Robinette- jam hard, working up from 32gr. of H4198, with neck tension .004 under size of finish round. 3 shot groups at 100 with flags shot at night. I adjusted the scope after the first group. Nothing spectacular. My guess is that...

Hey man. I hope I didn't offend you with my fire form bullet assessment, but it seems I may have with your mere mortals comment. I was not downing your efforts. I hope those bullets shoot in the zero's for you. It just hasn't been my experience and I tried pretty hard. If I could have got...

Ok. I will throw in a curve. I decided to make a run at making 30br brass. I have plenty of Varget and also had some LT31 In a powder thrower. Tried to fireform with Varget but brass was .002 shorter than the LT 31.

So, here is what the LT 31 looked like fireforming. I had not shot in a month or longer. By the end, I was doing ok with gun handling. It took 31.5 or so to get crisp shoulders. As long as I was between 31.5 and 32 or so, I went with it. Using 125 TNT jammed hard.

Sub H-4198 and use LT-30 same charge. 34.7 to 34.9 in 50 to 70 degree weather with a 112 bullet. Your bullet seating deep may vary. You will get the same results.

I will definitely give this a try and compare the two.The Lt. 31 is about 200 fps slower.

Had a couple of hours over the last few days to load and shoot some so I decided to give a run at making my own 30br brass from 6mm Lapua. I started off with 52 pieces and figured that would be enough to shoot a match if it all worked out.

I firefomed using tnt bullets and 31.5gr of LT31. The brass needed at least one more firing to get sharp shoulders, but it is close enough in to do some general testing. This is my first time shooting Lt 30 in this barrel. I had it shooting dots in a 30br Bat 3l that I sold.

I started off trying 35.3 of lt31 and then went to lt30.

Lt31 35.3 2951fps Lt.30 35.3 - 2297fps
35.6- 3011fps
36.0- 3033fps
36.3- 3065fps

Here is the target for what it is worth. This is the second firing on my newly formed brass and I can tell it was not fully formed based on the fps and errant shots.

One thing is clear. Lt. 30 is significantly slower than H4198. With 34.7 of H4198, I get around 3050. This is when the temperature was in the 80s. I shot the Lt. 30 in colder temperatures 30-42 degrees. Still, it is much slower. I will finish working up this load with Lt30 and then go back and compare H4198.
