Default .45-70 Microgroove v. Ballard

Hi All,
Was reading around the web and came up on the issue that Handi's have microgroove barrels for a time. Artifact of Marlin having owned them for a while.

Anyone know when that started and stopped?

Since I'm planning on cast bullets, would prefer the Ballard rifling. Wondering how likely it would be to end up with a Microgroove if I ended up ordering a rifle unseen?

Was microgroove long enough ago to make it unlikely end up with one new-in-box these days?

(Why do they keep monkeying with classic designs? LOL! Just make the good ones and be done with it, geez, I used to think firearms industry was immune to this stuff.)

my handy 45-70 looks like micro groove shoots the lead real good .my marlin lever action is not as accurate need to slug barrel to see if it is oversize.

Just because it is new in the box doesn't mean it was made last week.
I have seen many that are 4-5-6 years old or more.
Been stored in some big distributors warehouse for years.
Check the serial # is the only way to know for sure.

During the time that Marlin owned them, weren't all of the Marlin .45-70s getting Ballard barrels?

I bought mine in 1982, and it has a microgroove barrel. It's always shot cast bullets very nicely--mostly gaschecked RCBS 300 and 405 grainers, but some Lee plain-base too. At the time I bought this rifle I didn't realize that there was some sort of issue with cast bullets and microgroove. Lately, after reading a bunch of comments on this website and others, I've been watching to see if my Marlin has developed problems with cast bullets. Glad to say, not.

Marlin was still making H&R barrels in 2010, dunno if they still do tho, I believe they are, my 45-70 Talo Trapper which was made since then has the same rifling as my 2008 SS Ultra Hunter which I think i MG or at least a made for H&R Marlin version of it, read the entire thread below.

Mine is micro groove, and shoots cast just fine, it does seem to like oversized hard cast better than soft, and shoots them better when loaded on the warm end of lever gun pressures.


Here's an attempt at a picture of micro groove rifling if ya can zoom in far enough you can see small spiral grooves cut instead of the traditional narrow lands and grooves.

Don't let the "experts" fool ya, micro groove barrels will shoot cast just fine, size your bullets about .002" oversize and blast away !
