30BR

[Ccrider]

Spent some time with my 30br yesterday afternoon after adding weight to the stock. Put on a new scope and dialed it in-row A. Then shot 4 five shot groups playing with powder charge and seating depth. The last group looked promising.

Powder? Bullets? Primer?

 

[Ccrider]

Powder? Bullets? Primer?

Yes. To all three.

 

[Ccrider]

Ok guys. I could not resist. 35-35.4 Lt. 30; 205m Cline bullets.

2950 ish to low 3Ks are good places to try to develop a load. As always, your rifle will tell you what it likes. I have some LT30 but have no experience with it yet. With H4198 somewhere in the 33.5 to 35 gr range depending on the speed of your powder should give you a good accurate loading.

Neck tension? Seating depth?

 

[Ccrider]

Neck tension? Seating depth?

324 bushing. Jumped .16.

 

[BoydAllen]

.010 neck thickness, .330 chamber neck? On jump, did you mean .016?

 

[Ccrider]

.010 neck thickness, .330 chamber neck? On jump, did you mean .016?

My bad. Yes, .016 jump. The neck thickness is .010. I am not sure about the chamber. I bought the barrel used to try out .30 cal. Looks like it will shoot. A little more recoil, but easily manageable.

I will be switching to LT30 in the 30 br after the winter matches. I was advised by a good shooter that switched last year the groups with the LT30 shrunk when he lightened up on neck tension. Might be worth a try.

I will give 325 a try. My 5 shot groups are agging less than .2, with some zeros thrown in. I think I have to shoot better to group better.

 

[JEFFPPC]

Sounds like the LT30 is going to work for you just fine.

 

[Ccrider]

Trying out some Speer 125gr. First outing with them did not go well. They would not stabilize.

I upped the powder load significantly, working up until I got slightly tight bolt lift. They did stabilize with the stiffer load. I felt like they were going to shoot ok.

Had a few minutes this afternoon. Loaded 9 rounds and a fouler, increasing the powder charge each three shot group. Two of three loads were in the 1s. I can live with that with cheap bullets. I did not sort of weigh them. I just loaded and shot them.

I know this is a hot load so I will not publish the amount of Lt30 used. It may get someone in trouble if they don’t work up.

My 30br like the 125 TNT at 100 and 200 but fell apart at 300

 

[Bill Norris]

This was my load and it did O K but nowhere near the 112 Barts or 115 Bergers.

125 GR. SPEER TNT 1.588 O M 2.234 COL T/L B S .287
POWDER 30.0 GR. AA-LT-30 PRIMER CCI BR-4
SEATED @ 1.578 O M 2.224 COL .010 OTL .324 BUSHING
.338 5-SHOT GP. @ 100 YDS.

 

[Ccrider]

fell apart at 2900.

125 TNT is a fire form bullet. Wouldn’t compete with them.

 

[Fuj]

Yes Sir !! I use TNT's for fire forming.

 

[Ccrider]

Yes Sir !! I use TNT's for fire forming.

You guys are right about them being a cheap fireform bullet. If my three shot loads hold up at 5 shots, they will hold their on at small local matches. For most of us mere mortals, agging in the .1s is ok. Of course, I will have to see if the load is consistent and will repeat.

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 them to shoot with repeatable match precision, I'd be using them. I wish you well in your endeavors.
