    Would Underwoods 220 grain Hard Cast Flat Nose be too much for the G29? Even if the pistol is made to handle it would recoil be too much?

    I am running a 4.48 Storm Lake barrel on it with stock springs.

    It is rated for 1200 fps and 703 lbs muzzle energy.

    I shoot the 220 hardcast from Underwood in my G29 but it has a KKM barrel. It's a little smoky but as I understand it that's from the bullet lube. It feels like a big heavy bullet but is accurate. I have a 21# Wolff spring.

    If price were not an issue I'd shoot them all day and not worry about recoil at all.

    Good to know. 180 gr. Underwood is the usual, but was thinking about the 220gr. for the cabin and woods carry - seen too many black bears recently.

    Normally, I'd go right to the horse's mouth for that kind of info (Kevin @ Underwood) but I know enough about his quality, the charges used and the G29 design and I can say that the load is perfectly safe. Not only that, but he's obviously using new brass. I'd not be worried at all unless Kevin says specifically not to.

    Really, he isn't running loads for the 220s way over book like his other 10mm stuff? So the 220 is the one that is safe to shoot?

    His loads are within SAAMI.

    Separately, I feel like my G29 tends to have some fliers with anything above 180gr with the stock barrel. I am in need of an aftermarket barrel! Notice I said "need". I have a lot of "needs" when it comes to this kind of stuff! :)

    A heavier bullet doesn't necessarily mean more recoil.
    Actually, I often time feel the recoil of heavy bullet loads to be more "pleasant" than the light and fast loads.

    storm lake barrels have about the best case support out there right now, Id say you're good to go

    I believe that his loads are considerably overpressure by comparing the powder charge used in his loads to those suggested in reloading manuals, as well as by the velocity obtained. Most loads are at least a full grain over book max for bullet weight and profile. Considering the charge weights, that is 12%+ additional charge, which is closing in on the difference in charge weights between 40 s&w and 10mm...

    If his loads had actually been pressure tested, the info could be hugely helpful to the 10mm reloading community, but I have not seen or heard of any evidence of such happening.

    I wouldn't hesitate to run Underwoods 220 Grain Hard Cast Flat Nose thru my G29. I also have a StormLake on one of mine and I've run some 200 Grain Double Tap (before DT watered it down) thru without issues. You should get real close to the published numbers (Underwoods numbers) considering the StormLake Barrel is 'almost' Glock 20 length. (4.48 VS 4.60).

    The reviews are very good as well. One thing about Kevin Underwood; he's an honest man who doesn't fudge speed numbers and his products are by far, the best you can get for money spent. I am big fan of Underwood Ammo and you can carry and shoot it with confidence.

    Because StormLake Barrels have excellent case support (a tight smile) I would run a bunch of these flat nose's thru just to make sure they feed 100%. Also, consider some BEAR SPRAY on your belt.

    Be well
