| Actually, the SAAMI spec for the Swede is 46,000 CUP, which is about 52,000 PSI. Most published loads conform to this limit.
43.5 grains of H4350 gives me 2800 fps with a 129 grain pill, and 46.5 of RL22 gives me the same MV with a 140 grain pill. |

Absolutely!! Who would expect 2800 fps from a 140 grain pill in a 87 year-old Swede? Wonderful combination.
In your CZ 550, 45.5 grains is very likely quite safe.
Very roughly, a grain of powder in the 6.5x55 is 2,000 PSI peak pressure. With your cz, I would expect 45.5 to be a mild load. Problem is, all the loads I can find are for the old actions.

Per Hodgdon No. 27 Manual, 45.5 grains of H4350 and the 129 grain spire point yields 2703 fps at 45,500 CUP.
You're absolutely right. Maybe I can go up a bit.
I have a new barrel on order in this caliber, for a large ring action. I'm going to instrument it with a strain gauge. That way, I can develop my own loads, to modern pressures. |

| M-96 140gr SierraGK BTSP H4350 44gr gives me about 2800fps and 46gr gives about 2900fps. The 96 is a very strong action(Swede's were proofed in the mid 60K CUP). Some will say it is not as safe as the 98 mausers because it has less venting for escaped gases, lacks a third lug, etc. None the less the 96 is a robust action. For my old Hodg.#26 ed and older hornady info with IMR 4350 and 129grainers the max's are at 46grains. |

| lonnie and gsp...thanks for the replies. it's good to know that the load i use now (45.5 imr 4350) is listed as being below max in some older manuals. |

| Most of the reloading manuals will list the pressures produced by their loads. That old M96 Swede is a pretty stout action in spite of what you may hear. I have 3 of them that I shoot regularly. I don't abuse them by exceeding max loads. The Swedish rifles were well made and not shot to all hell as some of the German M98s were. The newer commercial rifles in 6.5x55 are even better. Best wishes.

| Husqvarna M96 Sporter * Win. 270 * Very good bore, * blue worn near muzzle * finish about 85% (K1028) $400.00 ======================== The 270Win is 65,000 psi SAAMI and 84,500 to 91,000 psi proof loads. Those Swedes must think allot more of the 96 action than is often inferred. |

| That rifle doesn't look like my m/96. Looks more like a m/98 to me. A HVA 1600-series, right? |

| Re 22 at 45.5 grains and either a Hornady A-Max bullet or SST bullet gives 1.1" 5 shot groups out of my 1903 Carl Gustaf with iron sights. As someone said above, Re 22 and the Swede go together like apple pie and ice cream.
