Sonoran First Attempt With slugs - BRK Sonoran .30

[Billm]

AoA has them for $24 per 140, which is a bit pricey, but it's worth a try!

I will give them a try.

I’m hoping form, or lack there of. Wind is a part of it I’m sure
. I just can’t get a sub-MOA group at 103yds with any projectile. I don’t expect to shoot sub-MOA every day. But, now 1.5” seems to be the best I can do. I do think that I need to build a shooting bench. I’ve tried barely gripping the rifle and letting the rest and bipod do the work, to using the traditional method of pulling the butt tight into my shoulder. I guess I’ll keep plugging at it.

If you’re gun is too low on the bench sometimes it puts your bofy in a tense position prone to movement. I try to be seated high enough to have the gun higher and my back straighter not hunched over.

I’ll take a look at what I’m doing, thanks.

Should mention to that i find myself shooting poorly when i get frustrated testing sometimes and just end up throwing lead down range instead of shooting well. Might be just me but perhaps a break would help. Remember too it doesn’t take a lot of wind @100 to really screw things up when you’re trying to judge a group

Frustration has definitely set in lol. I’m also seeing wind. I’m going to take a break. Maybe it’s time to go back to75 yards when I try again.

Well, I took a break from shooting for a couple of days as advised. I broke the cardinal rule involving any kind of tuning. I made multiple changes to the rifle, moderator, scope, target, position etc.. I did all of this at the same time. Which means I don’t know what had the greatest effect. I moved the target back to 75yds. Moved the scope back .25” ( I was straining to get the correct eye box. Opened the exit hole of the moderator, it wasn’t clipping, but I was concerned that it was disrupting the air. I turned the table, as I realized that my right elbow wasn’t making solid contact. Cleaned the barrel with a brass brush, Ballistol and patches. Swapped the Accu-Tac FC-5 G2 or the shorter Accu-Tac FC-4 G2 ( the 5 felt less stable to me extended). The wind was horrible 4-18 mph constantly changing directions. But, if I wait for no wind, I will rarely shoot. 2 shots to get it on target and then a decent 5 shot group. jSB 44.5gr 882 fps 160ish bar. I posted a couple of screen shots of my wind readings over 2 minutes. The winds changed from east to north to west and varied between. 4 and 12 mph. I actually shot this group ten to fifteen minutes earlier and the winds were stronger. But, I think I’m heading back in the right direction. Thanks for everyone’s help.

That's awesome for those conditions, right direction indeed!

Now you are getting there!!!!! 870-905 FPS is where I have had good results....My reg is at 170 bar and I am shooting right at about 895-898......Not sure if you were watching your Extreme Spread, but low single digits is very easy to obtain with just a few minor adjustments of the hammer spring.

It does suck having to take it out of the stock, so when I am working on the Hammer Spring, I don't bolt it down into the stock completely until I have a tight ES, then I go for a group.

Also a different moderator can make a huge difference. I did shoot it without one, but it seams the STO FALX I use tightens up the groups.

I just increased my reg to 170ish. Haven’t tried it yet. The pellets were pretty consistent. I will retune the hammer. I’ve got to readjust my trigger. It’s started letting loose on its own all of a sudden. Luckily I keep it pointed down range. Not really luck, gun safety was pounded into me at a young age lol.

I'm at that point with my TX200
Stopped shooting it a few weeks ago bc accuracy went for a crap. Saturday night I cleaned the barrel and it was fine, wire brushed choke, ran patches, swabbed it out. Then I went over every single bolt on it and the scope rings, all OK. Go to shoot it and the zero is wacked out - high and left. I got it close and accuracy got a bit better. Well today I shot it again and zero was off... again....pretty sure the scope (Airmax) is on its death bed. Soooo frustrating.

Yeah, it’s definitely frustrating sometimes. Hopefully you’ll get it worked out.

Too bad your Sonoran has such a high ES That is where mine is pretty much shooting right now with 45 grainers.

It’s tightening up. 179 bar, 865fps

Wow, starting to get dialed in,

Wow, starting to get dialed in,

Yes, finally lol.

3 shot group with my own swaged slugs at 100yds. I had a variable wind hitting 14mph. I deceived to quit while I had a nice min group in spite of the wind lol. Sub-MOA for sure - .774”. I had to go to a lighter slug, I went up to 51.9gr and the slugs were wobbling before they left the moderator.

What grain slug are you making now? That's a nice grouping; coming back and getting dialed in at 75 yards is paying off!!!

 

[Billm]

These are 48.7gr.
