Regrets?

[DeadEyeSly]

I am looking at the Howa mini hunter but cannot decide between the 20 vs the 22 inch barrel.  Anyone have any regrets with their choice of either length?

2” difference is barrel length will effectively not matter performance wise. I believe intended useage, handling characteristics and weight are what you should make your decision about.

I took the 22” sporter since overall it’s a “Mini” action and wanted light. GLW your decision.

It would be nice to be able to get hands on them but nobody near me carries them. Does your 22" heat up pretty quickly?

Been listening to the Hornady Podcast, trying to catch up, and recently listened to the Internal Ballistics episode. What they noticed, generally speaking, is about a 100FPS per inch

I went with the 20" heavy barrel version. It has the 5/8 threaded end versus the 1/2 threaded end. That will match my muzzle breaks and eventually suppressor with my gas gun build. In addition, the primary purpose for this will be target and a brief use for deer in the fall.

100 fps variance per inch of barrel is not right … either different bores/dimensions, different lots of ammo or something. I d guess 18-20 fps difference per inch on a cartridge shooting roughly 2600-2650 fps.

Sorry I m late responding but my sporter barrel doesn’t heat up very fast 5-6 rounds and it’s nothing close to a 6 CM or 243 firing some number of rounds.

Hornady has a pdf (108-110 gr gas gun) that also has a table of MV by the inch for a dozen or so velocities/powder charges, showing more or less 60 fps/2-inch barrel length, so ~30 fps/inch.  This has pretty much held for me for 16", 18", 20 and 22" barrels. Maybe a couple times, ~35/inch, but that's the ballpark I've seen.

I opted for the 20" HB and my cousin has the 22". The 20" is what I would call a traditional sporter weight, NOT heavy, and the 22" is the pencil thin barrel.

I have zero regrets as mine is a tack driver.

I have had 3 bolt action 6mm ARC rifles & all are equipped with lighter weight 22" barrels. I consciously make it a point with most all rifles to not fire successive rounds any faster than 10 second intervals. I have been rather impressed on how slow the barrel warms up. we are talking 5 & once in a great while 10 shot strings. Never actually measured the temperature of the barrel though. My really warm barrel may be a very Hot barrel to you.

The small powder column in the 6mm ARC is bound to reduce the heat. I have not shot a heavier barrel 6mm ARC yet to compare to my light contour barrels.

The barrels I have worked with was 1 Howa mini that started life as a barreled action from Brownells. Did a savage axis & that went down the road recently. did not like the little cartridge in a longer action was my biggest beef with that rifle. 

My favorite 6mm ARC is a CZ527 with a Pacnor barrel. I have had considerable trigger time with the CZ 527 in the last 3 years. Not so much time with the others.

I do have a heavier barrel spun up to try on the CZ & just have not felt the need to put that barrel to use yet. If I ever get around to purchasing a silencer the heavier barrel seems like she may be more fitting for that application IMHO.

My cousin tried a can on his 22" Howa pencil thin barrel and accuracy was dismal.  Without the can, it groups well, so obviously the harmonics were disturbed.
