I swapped the Skinner rear sight for a Burris 4x mini for deer season. Took it to Basspro's indoor range to sight it in. Started with a different target at 25yards. Ran a fresh target to 100yards. First two shots were high. Adjusted down for the second two. The second shot was a called wobble. Now if the deer will cooperate. https://uploads.tapatalk-cdn.com/202...1a1d90644a.jpg

Attachment 306512. Marlin 336 microgroove
Not sure where the idea that microgroove barrels aren't accurate originated but I've had a Marlin 1895 with microgroove barrel and have a Marlin 1894 with microgroove barrel and both handle cast bullets just fine!
One issue with the 1894's in .44 mag. is that the bore and groove are fat so "standard" 0.430" boolits generally don't shoot well. Fatten them up to at least 0.432" and it makes a world of difference!

You did not say what the caliber is ? What the load is ? You called this a wobble ? IMO For what I can see, These are tipping, not shooting straight?
All 4 holes are out of round ? Oblong ?
Might want to try a shorter bullet ? They will still kill deer. If you hit them.
With the mouth breathers and soft heads:
The truth doesn't stand a chance against a good, well established myth.
Bullets are definitely tipping and on the ragged edge of stability.
The caliber and load are written on the target.Quote:

A target hanging loose, without a backer, will also give that kind of hole in the paper.Quote:

As does many a target stapled up to "hasty" target hangers at many ranges I have used, where I see things such as the top tilted forward of base, hanger able to flop in the wind due to supports being housed in oversized receiving pockets, target paper being "puckered" because it wasn't stapled flat, etc.Quote:

I just think of the bullet like a draftsman: if the target isn't "true view" you are handicapped in analysis.
You missed that Bullseye by 3/8 of an inch!
Those sorry old Marlins[emoji16]

I have some Redfield targets like that and are over 30 years old. I read the instructions last week an they say to shoot at the corners of the diamonds. Fancy that.:killingpc I been doing it wrong.
Marlin micro grooved barrels have been shooting lead .22 rimfires very accurately for decades -
This has often been discussed here. Micro groove shoots lead just fine and I’ll add PC too.
My take on the "Inaccuracy" issue is that those shooters had no idea what "cast slug fit" is..
That is it exactly Mike!
If fit to groove is right there is no reason cast lead shouldn't shoot well in microgroove barrels.
My 1895 shot cast boolits from the get go and did so very well even with the hotest 1895 load data. I had trouble with my 1894 because I wasn't smart enough to slug it to ensure that I was using correct size boolits. The Lyman 429421 mould I mistakenly bought for that gun suffered two problems (for a Marlin)... the boolits cast at 0.429"/0.430" which is undersize for Marlin bores, and the crimp to nose length is too long for proper COAL. Not only didn't I get accuracy but I didn't get reliable feeding either. Both issues my fault for not paying attention!
With fatter boolits of 0.432" to 0.434" that gun shoots just fine and if cartridges are loaded to correct COAL they work too! DOH! Whoda thunk it!?!
I am not surprised by 7br's success with the .35 Rem. at all! That seems to me to be a good cast boolit cartridge design too.
To be honest, I am surprised that Marlin went away from the microgroove barrels but I guess there was customer pressure to do so.

I have a Marlin 99M1 22LR with a microgroove barrel that accounted for many a rabbit, all head shots.
My 'poor mans cowboy' 1895 in 45-70 is microgrooved, and once i found the right sized bullet mold- .461"- it shoots just fine at least out to 200. not bad for a $310 rifle.
The procedure is no different, slug the bore, cast to fit/.001" over.
I had some concern that the rifling was going to strip, but it has not happened as of yet. bullets do not keyhole as they did with the smaller lee mold boolets.
The myth that MicrogrooveŽ does not handle lead /cast bullets started with gun writers who dabbled in cast bullets.
They would read in the cast bullet manuals that bullets had to be sized to bore diameter.
Those of us who were shooting cast bullets discovered that cast bullets were more accurate when sized to 0.002" over bore diameter or larger, in normal rifled bores.
I discovered that my Marlin 30-30 liked bullets sized to 0.311" or larger (under 1" at 100 meters) but gave 6" groups with the same bullet sized to 0.309".
MicrogroveŽ barrels give remarkable accuracy with cast bullets when the correct diameter cast bullet is chosen
On a slightly different note.
Gun writers maligned the 303 British as woefully inaccurate when they loaded 0.308 Commercial bullets for bores that ranged from 0.311" to 0.314" during the 1950s and 1960s. They blamed the 2 piece stock for any inaccuracy.
I have a 303 (Martini No 3 rifle) with a 0.313 bore that will shoot under 1" all day at 100 meters if i do my part.
The same cast bullet sized to 0.312" will give keyholes and 16" groups
Because of gun registration and the introduction of the "magic" WSM calibers many old 303 rifles got traded in. I managed to collect a number and almost all turned out to be able to give me a 2" group or less at 100 meters with cast bullets.
Not bad for rifles that were made almost 100 years ago. or 70 years ago (the No 4 Lee Enfield).
I love it when a plan comes together.https://uploads.tapatalk-cdn.com/202...5562ff7ada.jpg

nice
25 edit I re read your post and saw that you also shot at 100. Now if I could get my browning 32 20 not to fall apart between 50 and 100
I shoot a Marlin 336 in 35 Remington. 200 grain RCBS cast bullet. 35/200 with 3031.
I love hunting with it.
Beautiful rife!! I have a common run of the mill 336 30-30 I bought new in 1974 from a TG&Y store back in the day. I haven't run 2 boxes down range since I got her. Often thought about selling her and getting a .35 but here she sets in the safe. Might just get a .35 anyhow.
Your original pic of the .35 just made my eyes hurt; don't know why but if rifle pics aren't oriented horizontal, I have to change them to enjoy. Just a psychological quirk I'm sure.
I hope you don't mind.
