What I am looking to test this Spring is IMR 7828, a slow burning single base powder.
Again, I don't know if that is a factor or not. I do know that the particular phenomenon I experienced just happened to be with RL22 which is a slow burning double base powder. I suspect that all have some sensitivity to temperature. Mike, I don't know if some powders are more sensitive or not. Some powders are more temperature sensetive than others. I'm sure there is an accuracy load down lower.
My goal is to drop all my loads by 3-4 grains. Be careful of shooting loads in hot summer that were developed in cool weather. Shucks, I know guys who hunt deer with 223.Īnother point that I think is important along this same topic. After all, the Swede is well over 2000 foot lb which is 800 lb more than the necessary 1200 fpi. The deer is not going to know the difference in 200 fps or 2 inches of trajectory. (prompted by the August issue) Trajectory and velocity are not that important. I'm presently in discovery of lower velocity loads. However, I do hear you on good, safe loading practices and appropriate eye protection. Surely any relief of gas is better than gas in the face. You say you don't hold with modifications, etc. I would find it hard to envision gas not being relieved adequately on a 98. I do notice that the Swedes have holes, considerably smaller than the M98 large slots. Hadn't thought about gas traveling down the raceway, but surely any escape route should help some. As far as I'm concerned, it is too small to do much good. I do have one rifle with hole in the receiver and aligned hole in the bolt. So I know that gas ports in the bottom of the bolt do help on pierced primers. Yep, pierced primer, and on one shot the primer fell out of the pocket. I was alerted only by a faint odor of powder to prompt me to open the bolt slowly. I've popped primers before, shooting loads in August that were developed in cool weather. Gas holes in the receiver ring do precious little to stop the gas headed down the bolt lug raceway. The gas ports in bolts may relieve some pressure to the magazine if a pierced primer is the source of the gas. Lighter bullets even mild loads all shot high. The Hornady round nose bullet weighing apx 175 grs would follow the sights pretty close. When I was younger with sharp eyesight I could print clusters with this rifle. Can't see it in the picture but the handguard is shorter but still fastened the same as the Arige with a copper wire. The Peru version used the Gew 98 type rear sight. I'll try and get a picture posted tomorrow if I don't have it in my files. The receiver and barrel are pitted but the bore is as shiny as a mirror. Identical to the Argie with the exception of the rear sight and handguard. As far as I know it hasn't been shot since the 60's. He still has the 91 Argie and it still looks near mint. Both bagged a deer and a few weeks later my friend was on his way in the Army and later the Nam war. He and his dad took the rifles deer hunting a couple days later. My buddy said he was teed off because his dad wouldn't spend another 50 cents each for bayonets. He claims his dad spent $45 and some loose change for two rifles and one box of Norma ammo. His dad bought two, both in mint condition. Shooting friend of mine likes to brag about his first rifle, an Argie, purchased in the mid 60's. If you value your eyesight don't even think about shooting one of these without good safety glasses. The escaping gas literally toasted the right lens of the safety glasses. If I hadn't been wearing safety glasses it would have seriously affected my right eye, likely blinded it. I was fire forming brass for my 91 and a blast of hot gas blew right back into my face. These have about the worst gas handling of the mausers so load with caution.Ĭan't say it enough!! I've said it numerous times before in this and other groups as well. There are only two mausers that use this caliber Norma knows it and makes sure not to go over their capability. Norma factory ammo works just fine, I have 2 1891's and have used Norma in both with no problem. Now, 25 years later, I finally got around to having it heat treated and will be putting together a 7x57. One day, I'd like a 1909 Carbine to match. They are still nice though, put together like a sewing machine. These have about the worst gas handling of the mausers so load with caution. 300 savage velocities & pressures you shouldn't have a real problem. The way I see it, if you keep loads at around. I have one box of Factory Norma ammo and I may just pull it down rather than fire it.

That said, it shouldn't be an issue because I will never load these to full potential. But, since the much covetted 1909 is, I'll assume so. I don't usually build on these so I have no idea if they are soft.
