I know in the past that the new Savage rifles with Microgroove rifling are not the best at handling cast bullets, to say the least. So what is the deal with hexogonal rifling in the Glock handguns. I plan to shoot cast and I hear that's just not done with a Glock ? That being said, and remember I'm new to semi-autos, what should I be looking for,or does this go for all or most semi-autos?
From what I gather, I just avoided a major costly error in purchasing a Glock.
That was close !
 
From what I remember Glock's are to use jacketed bullets only with the factory barrels. You can buy aftermarket barrels if you want to shoot cast bullets.
 
It's possible to shoot cast bullets safely in a Glock, but you have to take some precautions. The polygonal rifling accumulates lead quickly and pressure will increase to unsafe levels if you don't remove the buildup. I shoot cast bullets through my Glock 45, but clean religiously every 200 rounds to get all the lead out of the bore. You may need to clean more or less often depending on your load and bullet hardness. I've never had a problem or a high pressure sign.

If you want to be on the extra safe side, only shoot jacketed or plated, or get an aftermarket barrel with traditional rifling.
 
Like the ape said, keep your gun clean and you can shoot cast. Plenty of people do. Since when do Savage rifles have Microgroove rifling?
 
Microgroove rifling is commonly found on Marlin rifles, not Savages.

Lots of Glock owners buy aftermarket barrels with conventional rifling to shoot cast bullets with less leading, but the factory barrel will be fine as long as it is cleaned regularly. A piece cut from a copper scouring pad wrapped around a bore brush will remove lead fouling easily.
 
Thanx everybody for the info. And who sells these aftermarket barrel ? and B and tjhaile your so right .Got Savage on the brain today. Marlin came out with that in the mid '80's I believe and was a disaster with cast, could be done, but pressures were a problem too. Not too familiar with Marlin anymore. Don't know if they continued on with that ?
 
I have thousands of lead bullets through my G17's. No leading and very accurate. It actually is the best gun i have for lead bullets.

Poly rifling accumulates less lead than standard rifling, standard rifling shears off the lead and it accumulates at the edge of the land. once you get a little lead in your barrel it builds real fast.

Save your money, shoot with the factory barrel.
 
Not to highjack but how do plated bullets do in Glocks. Similar issues as lead or more like jacketed bullets?

Bingo. Shoot all the lead you want, just be sure to keep up on your cleaning.

It's funny how, back in the early 90's, before the internet we all shot thousands upon thousands of lead reloads through our Glocks and never had any hint of a problem let alone guns blowing up... Thank god the internet cam along in time to save us from ourselves... :rolleyes:

All I shoot now is AIM plated in my G17! I was shooting lead for the first year I had the thing, then found AIM and I am close enough to pick up the bullets myself so it is just slightly more expensive than lead. They can be pushed a little faster than lead but not like jacketed. I love em!

Lets see lead is $27.50 per 500 so $55 plus tax is $62.15...Aims just went up to $94.00 tax in, so the difference is $31.85 per thousand so really for the same amount of money you could shoot 1500 lead projectiles, don't get me wrong here I hate lead and shoot mostly copper, but the savings are significant if you shoot alot....

I am still shooting Aim's bullets that I got for $77 bucks a 1000 that was a deal...:eek:
 
another thing about some plated mfg is you need to be aware of the plating thickness used. In pistols with polygonal rifling, they may actually cut thru the plating surface.Result is poor accuracy as the flight path is affected by a bullet with peeling bits and tumbling
